The DevNet program described in historical materials now sits inside Cisco’s Automation certification portfolio. In 2026, the associate-level credential is CCNA Automation and the corresponding exam is 200-901 CCNAAUTO. The subject matter remains relevant—APIs, Python, network data models, version control and secure automation—but the certification name and preparation blueprint need to be checked against Cisco’s current exam documentation.
For an engineer new to network automation, a useful progression starts with gathering operational data from a device, comparing it with the intended state and making one reversible change through an authenticated API. Building repeatable tests and a rollback plan is essential before extending the workflow to multiple production devices.
The networking industry has spent decades operating within a world defined by command-line interfaces, proprietary protocols, and hardware-centric thinking. Engineers who built their careers on memorizing IOS commands and understanding spanning tree protocol could reasonably expect that the fundamental tools of their trade would remain stable over time. That expectation has been upended by a sweeping transformation in how networks are built, managed, and automated. At the center of this transformation within the Cisco ecosystem sits DevNet, a platform, community, and certification program that represents Cisco’s most deliberate investment in bridging the gap between traditional networking and modern software development. Understanding what DevNet is, what it offers, and what it demands of professionals is increasingly essential for anyone whose career touches Cisco technology.
DevNet evolved from Cisco’s developer initiative into a substantial technical ecosystem of sandboxes, APIs, sample code, learning labs and practitioner communities. Cisco previously used the DevNet brand for its network-automation certifications, but renamed the credentials CCNA Automation, CCNP Automation and CCIE Automation in 2026. The developer resources remain useful in preparing for the new exams, especially when a lab demonstrates how an API request changes observable network behavior. Exam preparation should follow the current objectives, not outdated titles found in older tutorials.
Origins and Evolution of DevNet
Cisco launched DevNet in 2014 as a response to the growing recognition that software was becoming as important as hardware in defining how networks behaved and how they were managed. The original vision was relatively modest: create a portal where developers could access APIs, documentation, and sandbox environments to build applications on top of Cisco infrastructure. What followed was a gradual expansion that reflected both the rapid evolution of network programmability and the growing appetite among network engineers for skills that extended beyond traditional configuration work.
Over the years DevNet accumulated a remarkable set of resources. Learning labs, code repositories, community forums, and eventually full certification tracks were added as the program matured. The introduction of the Cisco Certified DevNet Associate and Cisco Certified DevNet Professional certifications in 2020 represented a turning point, signaling that DevNet was no longer just a developer resource but a defined career pathway with formal credentials attached to it. The program has continued to grow since then, and in 2025 it represents one of the most active and well-resourced developer communities in enterprise technology.
Many professionals encounter the DevNet name and assume it refers exclusively to a certification program. In reality, DevNet is better understood as a complete ecosystem that supports network automation and programmability across multiple dimensions. The learning resources alone span hundreds of learning modules organized into tracks that cover everything from Python basics to complex network automation workflows. These resources are largely free to access, which has made DevNet one of the most accessible continuing education platforms available to networking professionals regardless of their employer or budget.
The sandbox environment is one of DevNet’s most distinctive and valuable components. DevNet Sandboxes provide always-on and reservation-based access to real Cisco infrastructure in the cloud, allowing learners and practitioners to experiment with APIs, test automation scripts, and practice configurations without needing access to physical hardware. For engineers who want to develop programmability skills but lack access to a home lab or a dedicated learning environment at work, the sandbox removes what would otherwise be a significant barrier to hands-on practice. The combination of learning content and immediately accessible practice environments creates a development loop that accelerates skill acquisition considerably.
Core Technical Skills DevNet Demands
Engaging seriously with DevNet requires developing a set of technical skills that may feel unfamiliar to engineers who built their careers primarily on traditional networking knowledge. Python is the dominant programming language in the DevNet ecosystem, and developing at least an intermediate level of Python proficiency is a practical requirement for anyone who wants to move beyond passive consumption of DevNet learning content into active development and automation work. The good news is that the Python skills required for network automation are relatively focused. You do not need to become a full-stack software developer, but you do need to be comfortable with data structures, control flow, functions, and the use of external libraries.
Beyond Python, DevNet practitioners work regularly with REST APIs, which have become the primary interface through which modern network infrastructure exposes its functionality to software. Understanding how to authenticate against an API, construct HTTP requests, parse JSON responses, and handle errors is foundational to almost every practical automation task in the DevNet world. Alongside REST APIs, familiarity with data formats like JSON and YAML, version control through Git, and configuration management concepts provides the technical scaffolding needed to build real automation workflows rather than just demonstrating toy examples. These skills represent a genuine expansion of the traditional network engineer’s toolkit, and developing them takes sustained practice rather than passive study.
DevNet and the Network Automation Movement
DevNet sits at the intersection of two powerful trends that have been reshaping enterprise networking for the past decade: the rise of software-defined networking and the broader automation movement that has transformed how IT operations teams manage infrastructure at scale. Software-defined networking separated the control plane from the data plane, creating the architectural foundation for networks to be managed programmatically rather than through direct device-by-device configuration. DevNet provides the tools, languages, and APIs needed to take advantage of that architectural shift and build automation workflows that operate at a level above individual device configuration.
The automation movement in IT operations, often described under the umbrella of NetDevOps or network reliability engineering, reflects a recognition that manual configuration and troubleshooting processes simply cannot keep pace with the speed and scale at which modern infrastructure needs to change. A network that serves a dynamic application environment, where workloads spin up and down, access policies change frequently, and new services are deployed continuously, requires a management approach that can respond at software speed rather than human speed. DevNet equips network engineers with the tools to participate in and lead that kind of automated, programmatic approach to infrastructure management.
Key Platforms and Technologies Covered
The DevNet ecosystem spans a wide range of Cisco platforms, and practitioners are expected to develop familiarity with the APIs and programmability features of multiple product families. DNA Center, now known as Catalyst Center, is one of the most prominent platforms in the DevNet curriculum, offering a rich set of northbound APIs that allow automation scripts to retrieve network inventory data, push configuration changes, trigger assurance workflows, and interact with intent-based networking features. Working with Catalyst Center APIs gives practitioners a concrete and practical introduction to what programmatic network management looks like in a production-grade environment.
Cisco’s SD-WAN platform exposes similar API-based automation capabilities, and the DevNet curriculum covers how to interact with the vManage controller to automate policy deployment, retrieve telemetry data, and manage device onboarding programmatically. Meraki, with its straightforward and well-documented REST API, is another platform frequently covered in DevNet learning content and often serves as an accessible introduction to API-based network management because its API design is particularly clean and beginner-friendly. Beyond these platforms, DevNet content covers collaboration APIs through Webex, security APIs through Cisco’s security portfolio, and data center automation through platforms like Nexus and ACI, giving practitioners a broad foundation for working across the full Cisco technology stack.
The DevNet Community and Ecosystem
One of DevNet’s less visible but genuinely valuable assets is the community it has built around network programmability and automation. The DevNet community forums, the DevNet Champions program, and the annual Cisco Live and DevNet Create events bring together practitioners from across the world who are working on similar challenges and developing similar skills. This community serves multiple functions simultaneously: it provides a support network for learners working through difficult concepts, a knowledge exchange for practitioners solving real-world automation problems, and a visibility platform for contributors who want to build a professional reputation in the network automation space.
The DevNet Champion recognition program acknowledges community members who make particularly valuable contributions through content creation, forum participation, conference speaking, and other forms of knowledge sharing. This kind of community recognition creates incentives for experienced practitioners to invest in helping others learn, which strengthens the overall community and accelerates the collective development of the field. For professionals entering the DevNet space, engaging with the community is not just a nice-to-have supplement to technical learning. It is a practical accelerant that provides access to perspectives, solutions, and relationships that formal learning content alone cannot provide.
Infrastructure as Code and Its Role
Infrastructure as code has become one of the defining practices of modern IT operations, and DevNet has embraced it as a core competency in the professional and expert-level curriculum. The principle behind infrastructure as code is that infrastructure configurations should be defined in human-readable code files, stored in version control systems, and deployed through automated pipelines rather than through manual configuration processes. This approach brings the discipline and repeatability of software development practices to infrastructure management, enabling configuration drift detection, rollback capabilities, peer review processes, and audit trails that manual approaches cannot provide.
Tools like Ansible, Terraform, and Python-based automation frameworks feature prominently in DevNet’s infrastructure as code coverage. Ansible in particular has become widely adopted in network automation contexts because its agentless architecture, YAML-based playbook syntax, and extensive library of network modules make it accessible to engineers who are comfortable with networking concepts but newer to automation tooling. The integration of infrastructure as code practices with Cisco’s programmable platforms allows teams to manage network configurations with the same version control and deployment pipeline discipline that application development teams have used for years, creating a more consistent and auditable approach to network operations.
Career Opportunities DevNet Opens
The career implications of DevNet skills and certifications are substantial and continue to grow as organizations accelerate their network automation initiatives. Traditional network engineering roles are evolving in ways that increasingly reward programmability skills, and entirely new role categories have emerged at the intersection of networking and software development. Network automation engineer, NetDevOps engineer, and network reliability engineer are job titles that have become common in enterprise and service provider environments, and these roles command compensation premiums that reflect the scarcity of professionals who combine deep networking knowledge with genuine software development skills.
For professionals who already hold Cisco’s traditional networking certifications like the CCNA or CCNP, adding current Cisco Automation credentials to their portfolio creates a differentiated professional profile that appeals to employers looking for practitioners who can bridge the operational divide between network teams and development teams. The combination of traditional networking depth and programmability skills is more valuable than either alone because it enables the kind of cross-functional communication and collaboration that network automation projects depend on. A practitioner who can speak credibly to both a network architect about traffic engineering requirements and to a DevOps engineer about pipeline integration is rare and correspondingly valuable.
Starting with DevNet does not require any prior programming experience, and Cisco has designed the learning path to be accessible to networking professionals who are approaching software development for the first time. The recommended starting point is the DevNet learning platform at developer.cisco.com, where free learning modules provide introductions to Python, APIs, and the core concepts that underpin the Associate-level curriculum. Working through the learning labs in sequence and using the sandbox environments to practice each concept as it is introduced provides a structured path from zero programming experience to a foundation sufficient for the Associate exam.
Building a simple home lab or leveraging the DevNet sandbox to work on personal projects is one of the most effective ways to accelerate skill development beyond what structured learning content alone provides. Writing scripts that interact with real APIs, automating tasks that you actually perform in your day job, and gradually increasing the complexity of your projects creates the kind of practical experience that makes certification content easier to absorb and makes the skills themselves more durable. Connecting with the DevNet community early in the process provides access to encouragement, guidance, and accountability that makes it easier to persist through the inevitable challenges of developing an entirely new category of professional skills.
What Organizations Gain From DevNet
From an organizational perspective, investing in DevNet skills within the networking team delivers benefits that extend well beyond the individuals who develop those skills. Organizations that build internal automation capabilities reduce their dependence on manual processes that are slow, error-prone, and difficult to scale. A network change that previously required a network engineer to spend several hours manually configuring dozens of devices can be reduced to a script execution that takes minutes and produces consistent, repeatable results every time. The cumulative effect of this kind of automation across an organization’s full portfolio of network change activities represents a meaningful reduction in both the time and the risk associated with network operations.
Beyond operational efficiency, organizations with strong DevNet capabilities are better positioned to take advantage of the programmable features in their existing Cisco infrastructure. Many organizations have invested heavily in platforms like Catalyst Center or Cisco’s SD-WAN solution without fully utilizing the automation and API capabilities those platforms provide. Building internal DevNet expertise allows organizations to unlock value from infrastructure they have already purchased, making the return on those investments more compelling and creating a competitive advantage in their ability to respond quickly to changing business requirements through programmatic network changes.
