Data Center Colocation Services: Best Practices for Managing Remote Infrastructure

Data center colocation services can help your customers stay secure

The demand for data center colocation services is on the rise, with the industry estimating an increase of 13.35% in 2022. Colocation services are often less expensive than maintaining an on-site data center, allowing you to redirect resources to more exciting and lucrative technology initiatives. However, remote infrastructure can be more challenging to monitor, secure, and troubleshoot. Plus, if you’re not careful, usage-based pricing could cause your budget to spiral out of control. Here’s what to know about the potential challenges and the best practices to implement to avoid common pitfalls.

Data center colocation services: Challenges and solutions

Challenge 1: Visibility

One way that data center colocation services differ from on-premises data centers is that there is often less physical access to and visibility over the infrastructure. Administrators can’t pop in every day to check environmental conditions like temperature and humidity or to verify that nobody has opened the cage without permission or physically tampered with the equipment. This can make it challenging to maintain optimal conditions to extend the life of your equipment and prevent catastrophic failure.

In addition, colocation facilities also follow the shared responsibility model, which means they’re responsible for a certain portion of security, and you’re responsible for the rest. The facility usually has security cameras, electronic door locks, and other security measures in place, but you generally won’t have access to the videos or logs as a customer. That means you need to ensure that you make up the difference with comprehensive monitoring solutions so there are no gaps in your coverage.

Solution 1: Environmental and infrastructure monitoring

Environmental monitoring sensors collect data on conditions in the data center, providing administrators with a virtual presence in remote colocation facilities. The sensors connect to the I/O ports of console servers and other infrastructure management systems, allowing administrators to monitor things like temperature, humidity, and air quality. Often, these systems use pre-set baselines and will trigger automatic alerts when conditions exceed safe levels, making it easier to efficiently monitor remote infrastructure.

Some environmental monitoring systems also include physical tampering sensors, which will alert administrators if someone opens the door to your cage or comes in close proximity to your equipment without prior authorization. This helps to supplement the physical security provided by colocation services and gives you more control over your remote infrastructure.

Challenge 2: Compliance with data privacy regulations

When the infrastructure used to store and process data is no longer managed on-site by in-house staff, it gets much more difficult to stay compliant with strict data privacy regulations. For example, if your organization processes HIPAA data, you need to know exactly who has access to that data, what specific data they access, and why they need access. That also includes access to the infrastructure that stores and processes the data.

If that infrastructure is housed and managed by a third party, as is the case with data center colocation, you need stricter privacy and security controls to maintain compliance.

Solution 2: Zero trust security

The zero trust security methodology is based on the principle of “never trust, always verify.” In the zero trust model, you microsegment your network to facilitate the creation of highly precise security policies and controls. This allows you to control exactly who has access to which resources in your colocation facility.

In addition, the zero trust methodology recommends identity and access management (IAM) solutions with two-factor authentication (2FA) and user and entity behavior analytics (UEBA). These solutions force an account to re-verify its identity and re-establish trust before it can move to different microsegments and access other resources. This both aids in data privacy compliance and limits the lateral movement of compromised accounts, improving the overall security of your remote infrastructure.

Challenge 3: Around-the-clock access to remote infrastructure

Colocation data center infrastructure is managed remotely over the WAN, which requires an internet connection. When administrators manage that infrastructure on the same production network used for data traffic, it’s known as in-band management.

The issue with in-band management is that it relies on the same LAN architecture that’s used in production. That means a misconfiguration or hardware failure that takes the LAN offline will also cut off all management access, making remote troubleshooting impossible. The same issue occurs if there’s a WAN failure or ISP outage.

If administrators can’t troubleshoot and recover the infrastructure remotely, you will need to dispatch a truck roll, which is both expensive and time-consuming. And, the longer that infrastructure is offline, the higher your downtime costs, including lost business and reputation damage.

Solution 3: Out-of-band (OOB) management

Out-of-band (OOB) management uses serial consoles with secondary WAN interfaces to provide an alternative path to remote infrastructure. OOB serial consoles create a dedicated management network that’s separate from the production LAN. This gives you the ability to perform resource-intensive orchestration workflows without negatively impacting production performance.

OOB management also allows administrators to remotely troubleshoot device failures, LAN misconfigurations, and other sources of outages. This reduces your reliance on truck rolls and helps you recover from outages quicker, so you can lower your costs and protect your reputation.

Challenge 4: Colocation bills

The cost of data center colocation services is generally dependent on your power and bandwidth usage as well as the amount of space your equipment takes up. If not managed properly, usage-based pricing can cause your monthly bill to vary dramatically, wreaking havoc on your budget. Many factors lead to usage spikes, such as sudden surges in demand and inefficient power distribution.

Plus, as your business grows and your technology requirements evolve, you may need to scale up the number of devices in your rack. And as you add more computing, storage, and server resources, you also need more management devices (e.g., serial consoles), all of which take up valuable real estate in the data center.

Solution 4: DCIM orchestration, SDN, and all-in-one devices

This particular challenge has multiple solutions, any or all of which can help keep costs in check while enabling easier scaling.

Data center infrastructure management (DCIM) solutions provide a centralized platform from which to monitor and control remote infrastructure. DCIM tools give administrators the ability to monitor power flows and redistribute loads on demand for more efficient power usage. Modern DCIM orchestration solutions also include automation capabilities for optimal power load balancing.

Software-defined networking (SDN) creates a virtual overlay network, dedicated to management and orchestration, that sits on top of the network architecture. This facilitates the use of sophisticated network automation workflows such as intelligent routing, which can automatically redirect traffic to alternative resources when the bandwidth load on your colocation infrastructure is too high. SDN can help you stay within bandwidth usage thresholds at your colocation data center(s), so you can use your services more cost-effectively.

Finally, all-in-one networking devices can help you reduce the number of boxes in your rack, so you use less square footage in the data center. For example, a device like the Nodegrid Serial Console Plus provides out-of-band management access, routing, switching, and network failover in a single box. Plus, it includes 96 managed serial ports in a single 1U rack-mount form factor, reducing the number of management devices required to control large-scale data center deployments.

ZPE, All-in-one Supervision

Founded in 2013, ZPE Systems is world famous but discreet despite its presence in France with large accounts. The company offers an all-in-one solution combining software, equipment and sensors to provide automation and orchestration on network operations and security.

Gartner covers the type of solution offered by ZPE under the term of Hyperautomation. ZPE is the Swiss army knife of network services by providing a solution to simplify and unify the vision of the network and the operations on this one. The solution can be deployed on site or from the Cloud. Locally, ZPE offers routers that supply the supervision console in the Cloud from different sensors or agents. It is possible from the console to configure, deploy, manage, and ensure access to implement the desired solution. The publisher’s operating system brings a layer of virtualization which makes it possible to accommodate third-party services such as for security, for example, in order to allow Out-of-Band supervision of all the IT components present in the company. On site, the solution comes in the form of an appliance which brings together all the functionalities and extensions allowed by a whole set of APIs to meet specific business needs. Thus, in September of last year, ZPE announced that it could ship Palo Alto Networks Prisma SD-WAN in its edge routers. In this case, the solution behaves like a mini Cloud at the edge.

Multiple advantages

ZPE brings the benefit of both all-in-one solutions but also the ability to easily deploy best-of-breed solutions with a supervision from a central and unique point, while avoiding the need to deploy, manage, and pay for licenses or subscriptions for disparate solutions. The solution consolidates the network stack and simplifies the operations of deployment, configuration, updating network scale and management. This makes life easier for the teams in charge of the network. Who has not experienced the ordeal of deploying remote networks or to try to find the cause of an incident on this type of site and to restore the faulty services? ZPE is particularly suitable for companies with many sites or highly distributed infrastructures

Nodegrid 5.6

During the last Cisco Live, held in Las Vegas during June, ZPE announced a new version of its Nodegrid OS available for its consoles and routers. Like its predecessor, the solution makes it possible to deploy best-of-breed at the choice of the company from the Cloud console of the ZPE solution. It is thus possible to deploy solutions embedding the various software from pre-validated suppliers.

Here is the list:

  • Ansible
  • Gluware
  • Stackstorm
  • On-ramp to Cisco SIG/Umbrella/CDFW, Fortinet, Palo Alto Networks’ PANOS firewalls, ThousandEyes agents

The solution thus provides a complete automation plan that can be orchestrated from Nodegrid for configuration change management, network monitoring and response to attacks and thus avoid service interruptions.

Data Center Orchestration with Gen 3 OOB for Digital Services Providers

ata center orchestration
Large digital service providers face some unique data center and network management challenges. Customers and shareholders expect 24/7, high-speed access to these services from anywhere in the world. The scale and complexity of their infrastructure, combined with their highly distributed, global network architectures, can make it difficult for administrators to meet those expectations. In this article, we’ll discuss how data center orchestration with Gen 3 out-of-band (OOB) management helps digital service providers achieve the reliability their customers demand while reducing expenses and complexity.

Use case: Data center orchestration with Gen 3 out-of-band for digital service providers

The businesses in this use case provide digital services at a very large scale. They need to ensure constant availability and reliability because that’s what their customers expect, and it’s what their competitors promise. Some examples of large digital service providers include:

★    Music or video streaming services
★    Stock trading applications
★    Online banking portals
★    Cloud compute services
★    SASE and SSE vendors
★    Internet service providers (ISPs) and telecom companies
★    Internet exchanges
★    Storage as a Service providers

These companies typically host their resources in private data centers or colocation facilities, so they have total control over the hardware and infrastructure. Because of the extremely large scale of their operations, they need to deploy, maintain, and administer many machines. And, since they typically provide global services, they have a large, complex, and highly-distributed network architecture.

There are several major pain points for network administrators in this environment. First, they need to maintain constant access to remote infrastructure, even during network outages. Second, they need the ability to scale up their infrastructure on-demand by quickly deploying new machines with the correct configurations. Finally, they need to be able to monitor, manage, and optimize their complex network architectures.

Let’s look at how these pain points are solved using data center orchestration with Gen 3 OOB.

1. Constant availability

People expect 100% uptime from their digital services, which is why it’s always major news when a big provider like Netflix goes down. To try and achieve constant availability, these vendors typically use their own hardware in private data centers and colocation facilities rather than relying on public cloud hosting. They host their infrastructure in many different facilities around the world, both for redundancy and to ensure peak performance for globally distributed customers.

Between hiring freezes and staff cuts at major companies like Apple, Google, and Netflix, many of these companies don’t have enough technical staff to maintain a physical presence in all of these data centers. Instead, their administrators and engineers access this infrastructure remotely, using tools like serial consoles, KVM switches, and jump boxes to connect to devices in the rack. However, if they lose network access to the management device due to an ISP outage, hardware failure, or configuration mistake, they’re left without a way to remotely recover. That means they need to either dispatch a technician from their home office or pay for costly on-site managed services from their hosting facility. Either way, valuable time and money are wasted on travel and other logistics.

Out-of-band management solves this problem by providing an alternative path to remote network infrastructure. Data center orchestration solutions with Gen 3 OOB use a secondary network connection (typically a cellular modem) that is dedicated to management and troubleshooting. That means administrators can configure, troubleshoot, and orchestrate remote infrastructure even when the primary network connection is offline or overloaded with production traffic. This gives digital service providers the ability to recover from outages and other issues much faster, bringing them closer to their goal of 24/7 availability.

2. Scalability

Large digital service providers need to serve millions of customers who may live all over the globe. They also need to meet sudden spikes in demand without limiting the performance of their product. That means they need to deploy lots of machines to many different facilities, often very quickly. Plus, they need to do so without configuration mistakes, as these could delay deployment, create security vulnerabilities, or even require a truck-roll to fix.

Since deployments need to happen quickly, accurately, and repeatedly, that makes them a prime candidate for automation. There are two primary technologies used to automate data center deployments: zero touch provisioning (ZTP) and Infrastructure as Code (IaC). A Gen 3 OOB data center orchestration tool enables both.

Zero touch provisioning gives administrators the ability to deploy device configurations to remote hardware over a network connection. Earlier generations of OOB data center solutions often included ZTP for devices within a specific vendor’s ecosystem, but Gen 3 tools are vendor-agnostic. That means administrators can remotely deploy an entire data center of mixed-vendor solutions without risking security breaches and the potential for opening a backdoor through pre-staging or on-site configuration. Plus, Gen 3 OOB provides a dedicated network to use in the provisioning process, so if there’s an issue with the configuration that takes the new device offline, administrators can still remotely recover.

IaC decouples a device’s configuration from the underlying hardware, turning it into software code that’s executed according to programmatic playbooks. Gen 3 OOB data center orchestration solutions support automation through IaC, either by integrating with third-party IaC platforms or by directly hosting playbooks. This allows administrators to apply DevOps best practices to infrastructure configurations, for example running automated tests to verify the quality and security of the code before deployment. IaC also reduces the time and complexity involved in configuring new devices, because scripts are easily reusable and can be deployed as many times as needed.

Through automation technologies like ZTP and IaC, Gen 3 OOB data center orchestration platforms allow digital service providers to scale their infrastructure quickly and efficiently. Automation also reduces the risk of human error, which reduces the chances that rapid scaling will cause service interruptions.

3. Network complexity

Large digital service providers have complex and distributed network architectures. They may have dozens or even hundreds of remote sites connected to the WAN, each of which may have different vendor hardware, bandwidth requirements, and security risks. Plus, there are many thousands of users accessing those resources from all over the world. In this kind of environment, manual network management is too time-consuming and prone to error.

Once again, automation is key to overcoming this challenge. Network automation is enabled in much the same way as infrastructure automation—by implementing software abstraction to decouple the management plane from the underlying hardware. This is known as software-defined networking (SDN) or, in the case of WAN architectures, software-defined wide area networking (SD-WAN). Digital service providers use SD-WAN to virtualize their distributed networks, employing software network controllers and APIs to route and load-balance traffic.

The right data center orchestration solution centralizes management of the entire SD-WAN architecture, giving administrators a single pane of glass from which to monitor and control the virtual network. Gen 3 OOB platforms are vendor-neutral, which means they can dig their hooks into all of the various hardware and software solutions that make up an SD-WAN infrastructure. They enable end-to-end automation of network management workflows and provide orchestration capabilities to automate the deployment and execution of those automated workflows. This makes it possible for digital service providers to manage their highly complex network architectures efficiently while maintaining optimal performance.

Gen 3 OOB data center orchestration with Nodegrid

The need for constant availability, easy scalability, and efficient network management is what brings many major digital service providers to ZPE Systems. The Nodegrid data center orchestration platform is the first Gen 3 out-of-band solution that enables end-to-end automation and complete vendor freedom.

The Nodegrid Serial Console Plus (NSCP) is a high-density serial console for large-scale and hyperscale data centers and includes features such as 5G/4G LTE cellular OOB and network failover to ensure 24/7 remote access. Built on the open, Linux-based Nodegrid OS, the NSCP supports integrations with your choice of third-party solutions, or you can directly host your automation, security, and SD-WAN applications on the device itself. Plus, the ZPE Cloud management software provides a centralized, web-based orchestration platform from which to deploy, monitor, and control your entire network architecture.

CIOs: 3 Boardroom Questions to Survive Winter Recession & Lockdowns

Winter is Approaching
The Dow recently posted decreases of 1,300 and 1,000 points within weeks of each other. Companies including Apple, Google, and Netflix have slowed hiring this year or outright cut staff. For CIOs, the message is clear: Winter is coming, and so is a recession.

We all know that company revenue is directly tied to IT infrastructure and the digital services it provides. In the simplest terms: network down, revenue down. So when economic downturns lead to hiring freezes and increasing workloads for IT, CIOs need to figure out how to ‘do more with less’ in order to maintain service levels. The reality is that we’d still expect IT to fulfill our support tickets even during the zombie apocalypse.

Today, business leaders are gearing up for the possibility of such challenges looming larger on the horizon, not to mention the potential for more covid lockdowns and other disruptions. No matter the reason, the expectation remains the same – keep networks reliable and secure.

Business leaders are uncertain about the coming winter

Business leaders are growing uncertain about the coming winter months because of the potential for more major operational shakeups, like those that occurred at the start of the coronavirus pandemic in 2020. This uncertainty stems from two looming possibilities:

As CIO, your peers will ask how you plan to increase top line revenue despite the winter recession, limited staff numbers, and potential lockdowns. This means you’ll need solid answers to three critical questions that will come up at your next board meeting.

3 Questions to Help CIOs Survive the Winter Recession

If we need to freeze hiring, can we continue to fulfill SLAs for internal & external digital services?

The IT workload has grown exponentially since infrastructure moved from centralized to decentralized. There’s just too much infrastructure scattered in so many data centers, colocations, and branch offices — from servers and routers, to branch gateways, remote sensors, smart building infrastructure, user experience monitoring applications, and firewalls. On top of this, pushing workloads to edge compute and 5G will inevitably lead to more micro and nano data centers that need to be maintained. Your IT teams are already struggling to keep up with everyday operations like configuration management, troubleshooting, and recovering down equipment. Now imagine how much stress they’ll endure if they’re unable to get additional help due to hiring freezes or pandemic lockdowns.

If staff can no longer physically access equipment, can we maintain IT availability?

As we saw at the beginning of the Covid pandemic, companies scrambled to find ways to accommodate normal operations while shifting staff to a fully digital workplace. But many companies were unprepared and are still struggling to adapt. In fact in 2021, IT organizations reported that their highest priority was to improve digital work for employees, but 66% said they didn’t have the capabilities to support the needs of remote and hybrid work. IT organizations must be prepared to accommodate flexible work well into the future, but this typically means employing a mix of local smart hands, third party service providers, and remote management solutions that significantly inflate operating costs. Despite any potential lockdowns, physical access can already be challenging when equipment resides at remote locations that are costly, inconvenient, or downright dangerous to access.

Will we be able to stay in compliance and keep up with security patches?

Many security breaches occur not because patches don’t exist, but because installing these patches might lead to unforeseen breakages. Some IT teams still run software that’s years old and several major revisions outdated. Meanwhile, these teams can only hope that vulnerabilities won’t be exploited and lead to business incurring regulatory fines or penalties. In a nutshell, systems go unpatched and grow more vulnerable as time goes on, because teams are afraid to risk breakages that they can’t easily recover from. This problem will only worsen when hiring is put on hold and physical site access is restricted.

Big tech has it figured out

Big tech companies have thrived on recessions and often come out stronger. How? Because they understand that they must empower their IT organizations during economic downturn. According to Gartner, there’s no better way to do this than to invest in digital transformation. But exactly what digital investments do these companies make? As CIO, you have such a large and distributed IT organization to wrap your arms around, that it’s difficult to define the practical steps you need to take. When answering these three key questions, your IT and executive teams will need to know: “How do you plan to accomplish this?”

Use big tech’s secret: The Network Automation Blueprint 

The network automation blueprint is made up of four major building blocks that create a management network design pattern to accommodate hyperautomation. These building blocks are:

  • IT/OT production infrastructure: This includes servers, switches, routers, and common production equipment.
  • Automation infrastructure: This is a truly independent network that enables automation to reach the production infrastructure in an out-of-band fashion.  Customers call this the double-ring network. This layer often uses a combination of serial console and Ethernet connections, and also includes staging jump boxes, local storage, TFTP source of truth, and version control systems.
  • Orchestration and automation systems: This is where the desired outcome and playbooks are sourced from. The key is that the orchestration reaches the production systems through the independent out-of-band network to achieve the desired outcome.
  • AI Ops infrastructure: This layer receives rich information from observability platforms to make reactive and predictive decisions at scale. Using machine learning and artificial intelligence, this layer learns the network’s normal behaviors and pushes changes through the orchestration and automation layer.

This blueprint is the reference architecture validated to successfully implement Gartner’s definition of hyperautomation, as well as meet the Open Networking User Group (ONUG) Orchestration and Automation recommendations. This blueprint gives you the necessary layers to confidently answer the three questions that will come up during your boardroom meeting, and outlines the practical steps required to achieve IT resilience. Here’s how it answers these questions:

If we need to freeze hiring, can we continue providing reliable IT services?

By separating the automation infrastructure from the production network, teams can build hyperautomated environments while having a safe way to recover from errors. Despite having limited staff and/or a virtual workforce, teams can develop their automation pipelines to reduce workloads and meet SLAs.

If staff can no longer physically access equipment, can we maintain IT availability?

With the network automation blueprint, teams get a management network design pattern that ties into all of their solutions. This means they get a full virtual presence to manage SD-WAN, firewalls, switches, servers, routers, and their entire stack. The blueprint also calls for running automation locally so workloads can be carried out despite connectivity problems. These allow teams to maintain their sites and availability across distributed architectures.

Will we be able to stay in compliance and keep up with security patches?

Automating via out-of-band means teams no longer need anxiety about the dreaded Friday night upgrade. Instead of running outdated software and configurations because “if it ain’t broke, don’t fix it,” teams can ensure the integrity of updates before pushing them live. This allows them to take advantage of the latest software releases, close security gaps, and maintain compliance.

Meeting customer expectations for always-on digital services is a major challenge for any enterprise. That’s why it’s important for CIOs to empower their teams with hyperautomation and automate as many processes as possible. The network automation blueprint gives you the reference architecture that’s been validated by big tech as the safe way to build hyperautomated environments. This blueprint is now available just in time to help organizations prepare for the looming winter recession.

What is a Serial Console’s Role in Modern Enterprise Networks?

what is a serial console

Serial consoles have been used to manage business networks since the 80s, but things have changed significantly since then. What is a serial console’s role in modern enterprise networks? In this blog, we discuss the history and evolution of serial consoles as well as the exciting functionality provided by the latest generation.

What is a serial console?

A serial console—a console server, terminal server, serial console router, or serial console switch—is a networking device used to manage other devices. It connects to servers, switches, routers, and other equipment using the serial port (hence the name). Network administrators can then use the serial console to access all connected devices in the data center, server room, or network closet in which it’s installed.

Serial consoles allow admins to manage critical infrastructure without needing to log in to each separate device individually. A serial console also provides out-of-band (OOB) management, creating a completely separate network that’s dedicated to infrastructure management and troubleshooting. OOB management allows you to remotely troubleshoot, monitor, and administer your infrastructure, and more.

How serial consoles have evolved over time

A basic serial console—also called a Generation 1 serial console—provides consolidated remote access to critical infrastructure. It uses a secondary network connection (such as a dial-up modem or cellular SIM card) so admins can control and troubleshoot equipment without relying on the main production network. Using a Gen 1 serial console, admins can access each connected device’s CLI (command line interface).

Gen 1 serial consoles are relatively limited in control, security, and automation. For example, many Gen 1 serial consoles can only manage devices from the same vendor (or a small pool of supported manufacturers). A Gen 1 serial console also lacks in-depth security features like hardware encryption, and generally can’t integrate with third-party Zero Trust Security policies and controls. Plus, most Gen 1s completely lack automation capabilities, or limit you to basic CLI scripts for single tasks.

Gen 2 serial consoles

Frustration over these limitations led to significant advancements in the second generation of serial consoles, or Gen 2. With Gen 2 serial consoles, admins get more control, added security features, and expanded automation capabilities.

For instance, most Gen 2 consoles offer management functionality for third-party devices. These serial consoles also have some built-in security features like Trusted Platform Module (TPM) and frequently support advanced authentication methods like AD/LDAP, Kerberos, and RADIUS. Gen 2 serial consoles also allow for greater automation using Python scripts, APIs, and zero touch provisioning (ZTP).

While Gen 2 serial consoles offer more multi-vendor support than their extremely limited predecessors, they still fall short of true vendor neutrality. For instance, managing third-party and legacy devices often requires expensive adapters or complicated configuration tweaks. Many Gen 2 serial consoles also lack support for Zero Trust integrations such as SAML 2.0 (e.g., Okta, Ping, DUO), making it impossible to completely secure your out-of-band network.

Finally, while Gen 2 serial consoles introduce more automation capabilities, their closed architectures make it impossible to implement end-to-end NetDevOps automation. For example, you might only be able to use one specific scripting language or an approved set of playbooks. It’s also common for Gen 2 serial consoles to only support ZTP of connected devices from the same vendor, so you’re either limited in your automated provisioning capabilities or your choice of infrastructure solutions.

Gen 1 serial consoles provide remote, out-of-band management of multiple devices using CLI commands and scripts over a serial connection. Gen 2 evolved to incorporate more devices, more security features, and more automation capabilities. However, the serial console needed to develop even further to handle the needs of a modern enterprise network.

What is a serial console’s role in modern enterprise networks?

Today’s enterprise network is larger, more complex, and more distributed than Gen 1 serial console developers could have possibly imagined. Network administrators and engineers need to monitor, manage, and troubleshoot infrastructure devices from many different vendors in many different locations. Networks are also constantly threatened by cybercriminals using sophisticated hacking techniques and state-of-the-art malware. Plus, modern businesses must ensure near-constant availability and optimal network performance to stay competitive. Gen 1 and Gen 2 serial consoles simply can’t deliver the control, security, and resilience required by enterprise networks today.

The new Gen 3 serial console addresses older generations’ limitations through true vendor neutrality, multi-layered zero trust security, and end-to-end automation capabilities.

Total infrastructure control

Gen 3’s complete vendor neutrality makes it possible to extend your automation capabilities—including zero touch provisioning—to every physical and virtual asset in your environment, regardless of manufacturer. Gen 3 serial consoles also give network administrators a virtual presence in remote network locations (like data centers and branch offices) through which they can monitor environmental conditions in the rack, power-cycle and enter the BIOS menu of devices, manage power load distribution, and more.

This control is delivered via high-speed OOB (such as a 5G/4G cellular SIM card), giving you 24/7 remote access to critical enterprise infrastructure, even during an ISP outage. Plus, Gen 3 serial consoles use centralized cloud management, which means engineers can manage and troubleshoot remote infrastructure from anywhere, anytime.

A Gen 3 serial console is based on an open architecture, x86 OS, that supports integrations with your choice of infrastructure solutions, cloud services, and automation toolkits. It also includes flexible port configurations and legacy pinouts to control a variety of devices, such as PDUs, IPMI devices, and environmental monitoring sensors.

Comprehensive security

On a hardware level, Gen 3 serial consoles use features like encrypted disks, UEFI secure boot, and TPM 2.0 to ensure unauthorized users can’t access management functionality. Additionally, the OS is frequently updated and patched against new security vulnerabilities before they can be exploited. The Gen 3 serial console also automatically checks the integrity of all newly integrated hardware and software to ensure there are no backdoor vulnerabilities.

A Gen 3 serial console’s vendor-neutral platform supports easy integrations with a variety of zero trust security controls. For instance, you can manage user access to a Gen 3 serial console through third-party Identity and Access Management (IAM) solutions, allowing you to follow zero trust best practices like 2FA, SSO, and dynamic trust verification. A Gen 3 serial console can also integrate with on-premises and cloud-based network security solutions such as next-generation firewalls (NGFW), Secure Access Service Edge (SASE), and Security Service Edge (SSE).

A Gen 3 console includes robust onboard security features, which reduces the risk of an attacker using a stolen serial console to access your management network (and ultimately, your production systems and data). Its open architecture also enables integration with zero trust security controls and providers.

End-to-end automation

The open architecture of a Gen 3 serial console makes it possible to integrate with your choice of infrastructure automation and orchestration tools, or directly host VMs and Docker containers so you can run your own tools. With a Gen 3 serial console, you can use solutions like Ansible, Chef, Puppet, or Kubernetes to automate deployments. You can also use any API you want to automate any workload you need to, no matter how complex.

Gen 3’s advanced automation capabilities enable full pipeline automation so you can achieve NetDevOps transformation. Gen 3 serial consoles also facilitate immutable infrastructure, allowing faster and more agile deployments, updates, and replacements of critical network resources.

With a Gen 3 serial console, you can create a fully-automated network environment. This allows engineers to work more efficiently and reduces the risk of human error causing an outage or security breach.

Nodegrid Serial Console Plus (NSCP)

A Gen 3 serial console, like the Nodegrid Serial Console Plus (NSCP), gives you complete remote control over every component of your network infrastructure, regardless of location or manufacturer. Nodegrid also secures your OOB management network using zero trust security best practices and comprehensive onboard features. Finally, the Gen 3 NSCP allows you to automate whatever tools you want to use, so you can efficiently manage a complex enterprise network without sacrificing speed, security, or control.

Branch-in-a-Box: Why All-in-One Devices Are the Future of Networking

shutterstock_588813473(1)

A branch network consists of many moving pieces that need to be remotely deployed, managed, and supported. That typically means separate devices for all the key functions like routing, switching, security, etc. However, as data and applications grow more distributed—especially due to the popularity of edge computing—it becomes harder for IT teams to keep up with the growing number of vendors and solutions at the branch. Branch-in-a-box seeks to solve that problem by delivering all your branch networking functions in an all-in-one device.

What is branch-in-a-box?

Branch-in-a-box consolidates an entire branch networking technology stack into one piece of hardware. A branch-in-a-box solution might include gateway routing, voice and data switching, firewall, Wi-Fi, and other crucial functionalities. Instead of learning, installing, managing, and troubleshooting five different boxes at each branch location, you only have to worry about one core device.

Next-generation branch-in-a-box solutions typically rely on the following branch networking technologies:

  • SD-WAN: Software-defined wide area networking, or SD-WAN, abstracts WAN management from the underlying MPLS, broadband, fiber, and cellular connection hardware. You can create intelligent routing policies to distribute and route WAN traffic for optimal network performance, with SD-WAN. SD-WAN intelligent routing also facilitates cloud-based edge security technologies like SSE (security service edge) and SASE (secure access service edge).
  • SD-Branch: The limitation of SD-WAN is that its capabilities generally end at the branch gateway. SD-Branch extends your software-defined networking functionality into the individual LANs so you can automatically manage and optimize traffic within the branch.
  • Compute: Some branch-in-a-box solutions also come with compute capabilities or modules. Meanign you can run guest operating systems—like VMs (virtual machines) and containers—without needing to install additional server hardware.
  • Out-of-Band: Out-of-band (OOB) separates your branch network’s management plane from the data plane so you can remotely manage and troubleshoot your branch infrastructure from a dedicated connection. With OOB, you get one unified control panel from which to remotely monitor and administer all your branch networking devices. OOB also provides an alternative path to your branch network, often over a cellular connection, so you don’t need to rely on the primary WAN link. You can troubleshoot and recover from outages remotely, reducing costly truck rolls.

SD-WAN optimizes traffic to and from the branch, ensuring optimal performance and productivity in all your remote locations. SD-Branch extends your reach into the individual branch LANs to give you more control over network routing and performance. Compute capabilities let you run VMs and containers without deploying additional servers. Finally, OOB ensures you always have access to your branch infrastructure, even during a WAN outage. A branch-in-a-box solution harnesses those technologies to give you control over a consolidated networking stack including routing, switching, firewall, and Wi-Fi capabilities.

Where did the concept of branch-in-a-box come from?

Let’s say the typical branch network relies on five boxes—a gateway router, a voice switch, a data switch, a wireless access point (AP), and a firewall. Five devices may not seem like a lot; and using a separate box for each branch networking job means you can, theoretically, choose the best-of-breed solution for each. If you only have one or two branch locations and a large, well-trained IT staff, then supporting multiple branch networking devices probably won’t be a problem.

But what happens when your business grows, and you need to scale up to 10 branches? And then 100 branches? And then 1,000? Suddenly, five best-of-breed devices turns into 5,000 individual boxes you need to purchase, configure, maintain, and troubleshoot.

Branch-in-a-box solves this problem by rolling-up all your crucial branch networking devices into one consolidated solution. This helps you save money on equipment, both in terms of the up-front costs and the recurring costs of licensing, software, and support. Device consolidation can also decrease the power consumption at your branches, saving you energy costs and reducing your carbon footprint. Deploying a branch-in-a-box is often faster and easier since you only need to ship and install one box instead of five.

Plus, an all-in-one branch networking solution reduces the overall complexity of your enterprise network by decreasing the number of devices and platforms that your engineers need to learn, manage, and support. That means your IT operations team can work more efficiently, spending less time on individual maintenance tasks and more time optimizing your branch networking. It also reduces the risk of configuration mistakes and other human errors that could potentially bring down your branches.

The challenge of branch-in-a-box

Of course, when you replace many different boxes with one solution, you run the risk of vendor lock-in. Suppose your branch-in-a-box solution runs in a closed ecosystem. In that case, it’s critical for that one box to truly cover every branch networking capability you need, because you won’t be able to extend its capabilities with third-party tools and devices. Plus, you’ll be forced to follow that vendor’s feature and support roadmap, which may diverge from your organization’s future goals and requirements.

To avoid these issues, it’s crucial to select a vendor-neutral branch-in-a-box that runs on an open platform, like Nodegrid.
