  • The Rise of NetDevOps and CI/CD Pipeline Solutions

    The Rise of NetDevOps and CI/CD Pipeline Solutions

    Over time, as organizations, networks and technologies have changed, the way enterprises think about managing networks has shifted as well. Enterprises are continuing to evolve their networking strategies, specifically with regard to how they expand their efforts to adopt infrastructure-as-code (IaC) practices. Looking ahead, the industry will continue to see the proliferation of solutions that help teams adopt a modern network operating model that delivers an agile, data-driven change management process. In most organizations, the software development team members and the networking team members have operated independently, with separate tools and processes. Developers would leverage pipelines to test and deploy code and then open a ticket for network changes such as VPNs or firewall changes. The network team would implement the changes, and end users could then use the application. The handoff between dev and network could be immediate or, more likely, it could take a few days–delaying the ability of the end users to access the new functionality. NetDevOps is focused on addressing this situation, which has become one of the market’s more critical infrastructure questions: How do you build an organization that can function smoothly across different skill sets, different technologies and different processes? Those same enterprises will be looking to leverage continuous integration/continuous delivery (CI/CD) practices from their software development best practices to help them overcome some of the challenges involved with implementing automation and orchestration into their networks.

    CI/CD Accelerates the Automation Process

    Let’s start with CI/CD. Adoption of network automation and orchestration will accelerate as network operators change the way they think about network updates and configuration management. According to Cisco’s recent white paper on how “Automation is driving network engineer skills transformation,” the reasons we’re seeing an increase in automation adoption is due to organizations relying on continuous connectivity, a greater need for the network to become more dynamic and the increased rate of changes both in the service supply side (applications) as well as in the service demand side (application consumers).

    However, some enterprises trying to build their own automation infrastructure struggle with resourcing, skill sets and maintenance effort struggles. To solve this, many of them are looking to incorporate the traditional DevOps practice of building and updating code with traditional continuous integration/continuous delivery (CI/CD) pipelines into their network automation and orchestration initiatives.

    Establishing a CI/CD pipeline is a workflow best practice for DevOps teams to follow. Today, organizations rely on CI/CD pipelines to help minimize bottlenecks in the software development and delivery process, while continuous integration optimizes building, integrating and testing code within a development environment.

    By integrating both CI/CD with network automation, teams will gain greater velocity and improve delivery. And by integrating network automation with an application CI/CD pipeline, they can reduce the time to perform network changes and enable secure access between the application and an in-house sales database.

    Why NetDevOps?

    NetDevOps brings the culture, technical methods, strategies and best practices of DevOps to networking.

    When DevOps principles are applied to network operations, organizations minimize operator interactions and optimize programmable network processes to configure, deploy and manage the environment, increasing efficiency and ensuring network availability, quality and reliability.

    NetDevOps takes those principles and applies them in a networking environment, offering tools to empower teams to collaborate and build an organization that can function across different skill sets and different processes — enabling everyone to participate in network orchestration.

    And it’s a movement that’s taking hold. According to Cisco’s Hybrid Cloud Trends report, 55% of those surveyed have created a cross-functional team with technical and business representation and 50% have a centralized CloudOps and NetOps function to help ensure their organization’s hybrid cloud strategy meets business objectives.

    Network Management Tools Will Continue to Evolve

    In today’s networking environment, where the expectation is to have an “always on” approach, teams are expected to build and release new applications at a faster pace than ever before. And every team has its own processes and methods for doing that which can create delays in the time it takes to execute the application. Incorporating network automation into the pipeline can empower teams to make application changes and deploy them to the network in seconds instead of the multiple days/weeks required for manual network changes. By integrating CI/CD pipelines and NetDevOps principles with network automation and orchestration, organizations can reduce the network change bottleneck even more.

    As we face the new year, we expect the way in which teams consume network automation and orchestration services as part of their software pipelines to become more sophisticated, with NetDevOps and CI/CD practices becoming a standard. And as more services become available, the adoption of IAC becomes easier. By abstracting and tweaking to abstract the traditional CI/CD pipeline, organizations of all sizes can accelerate the use of network automation and orchestration.

  • Bridging the Network Automation Skills Gap

    Bridging the Network Automation Skills Gap

    With the introduction of network programmability and APIs for everything from management systems to devices themselves, the modern network landscape has evolved to being managed like software. This shift from hardware-focused networks to software-centric functions has had a profound effect on network management techniques and skillsets required to keep pace with the changing ecosystem.

    A recent EMA survey notes that skills gaps associated with network automation are an issue for 96% of enterprises. Even respondents with significant network automation initiatives in place felt their solutions stretched the abilities of their network teams. Network automation can expose skills gaps where network engineers might lack experience with new tools and software development. At the same time, application development teams, who likely would be included in building an in-house network or automation software solution, will also lack networking skills. Hybrid skills with both development and networking expertise are rare and available only at a premium.

    This journey to network automation can be difficult, especially given the required technical skills that are not in abundance within many organizations. Simplifying network automation and empowering a broader set of participation through capabilities to easily create and manage automation workflows presents a key opportunity for organizations to not only mature efforts around network automation, but to also execute against broader business digital transformation objectives.

    Four Keys to Democratizing Network Automation

    The key to democratizing network automation and bridging the skills gap is to provide NetOps teams with the ability to easily design and build network automation without having to re-tool, build custom code or learn specialized software skills. There are four key elements required to effectively democratize network automation in the enterprise.

    Easy Onramp for Non-Developer

    Automation is typically accomplished through writing code in a particular programming language. For a person without any programming skills (or even minimal skills), they must first learn how to code before they can even attempt their first automation task. This is very difficult in terms of time and interest. Additionally, many network engineers see the amount of work it would take to learn to write code, and become disinterested. There has to be a new set of tools and methodology to empower these people to automate their work without the long road of learning to become programmers. It’s important to invite as many people to the automation table as possible including IT, security, cloud and NetOps teams, to streamline business processes.

    Capture Network Tribal Knowledge

    Within the organization, there is already existing embedded tribal knowledge that is incredibly valuable. By harnessing and transferring that knowledge into an automation workflow without a lot of programming, it provides an accelerated path to network automation. The goal is to leverage traditional network automation and management practices (Scripts, CLI) for re-use across the organization.

    Network engineers with years and years of experience have a valuable set of processes and procedures they’ve built up inside their heads, and this wealth of information is a valuable asset. Unfortunately, this information is rarely documented and is normally passed on by activity and word of mouth. This is the type of tribal knowledge that needs to be captured, preferably through automation workflows that can be used in a task, documented in the workflow and modified over time to improve it or change it as the infrastructure changes.

    Integrate DevOps Principles

    Augment network automation with CI/CD pipelines and API services. These are well known solid principles that are already used in other domains outside of networking and pay big dividends when applied to the automation of complex networks. When we look along the horizon of the network automation journey, these same CI/CD practices will be adopted by future networking teams and allow them the same advantages of reliability and velocity within the network.

    Enable Cloud Architect Participation 

    It is important to have networking people that can understand the networking constructs of the cloud, as well as cloud teams that understand how it integrates and operates within the network. Enabling cloud architect participation in network automation will allow for the real-time feedback and control of cloud-based applications and infrastructure critical to modern networks.

    Cloud networking is increasing in complexity and will soon require the skills and experience of network engineers to help solve the problems of cloud networking. Traditionally, cloud and networking teams have been separated because their technology domains have been siloed and there was very little interaction required between the teams. As technologies like SD-WAN have been adopted, the line of responsibility between cloud and network teams has blurred. Cloud and networking teams will need an automation platform that can be used by both to create workflows and automate between both domains. Business technology decisions are forcing these two groups together, and they must have a way to use their own tools, but also have a platform to collaborate automation between them.

    As applications and services are becoming more complex, distributed and require connectivity and policy enforcement across a diversity of domains (such as cloud, SD-WAN, data center, wireless and network applications), the management of these network concepts requires us to re-think how we have traditionally managed networks. As network automation plays an increasingly larger role in enterprise networks, a byproduct of the complexity is a skills gap that threatens to slow or stymie enterprise initiatives.

    By making the onramp to network automation easier for non-developers through capturing tribal knowledge, integrating DevOps principles and enabling cloud architect participation, enterprises better ensure a successful migration to network automation across multiple domains.
