Different Domains, Different Tools, Different Skills Cisco’s mission is to provide consistent automation, Day-2 Operations, and secure transport to the Clouds, within Clouds, and among Clouds. With the IaC paradigm expanding across organizations, the need to unify NetOps, DevOps, and CloudOps teams is crucial. With Infrastructure-as-Code (IaC), network infrastructure deployments become as fast and automated as DevOps has achieved for application deployments. With SDNs, applications and the network are part of a single system, where the network is designed and deployed according to the requirements of applications and an optimized user experience.Īn SDN is changeable and adaptive as applications are growing, reconfiguring, and reallocating to reliably deliver the desired business outcomes.Public Cloud, Private Cloud, Hybrid Cloud: the Clouds are all around us, helping to accelerate application delivery. SDN centralizes management by abstracting the control plane from the data-forwarding function in the discrete networking devices. Software-defined networking (SDN) is an architecture designed to make a network more flexible and easier to manage. What is a software-defined network (SDN)? Ideally, NetOps, DevOps, and SecOps are interdependent and form parts of a collaborative process. NetOps, DevOps, and SecOps are all relatively new methodologies in three areas-networking, development, and security-involved in successful agile deployments. How does NetOps relate to DevOps and SecOps? In the past, the missions of development and network teams often clashed, with developers prioritizing robust applications and rapid deployments, while network teams prioritized availability, reliability, and capacity. It's a mindset that may require cultural shifts to be fully embraced. However, NetOps is not simply deployed through technology. These tools allow DevOps teams to make configuration changes and update devices automatically. For example, tools originally designed to help automate workflows, such as Ansible, Puppet, and Chef, have been upgraded to include network operations in their process. In some cases, NetOps can be adopted through technology. A consistent view across infrastructure and applications data allows NetOps and DevOps teams to share a common view of the data. NetOps brings DevOps concepts like automation, orchestration, and virtualization into network operations, allowing it to be part of the development process. NetOps teams need an integrated view of health and performance, as well as insights so they can take action faster. With the rise of complex digital enterprises and the need for greater agility and faster content delivery, the network-and network management-must play a bigger role in the development process. Historically, networks have been an obstacle to agile development, managed manually and in a reactive, unplanned way, with an emphasis on availability rather than performance. To support this goal, DevOps has incorporated tools such as automation and orchestration to dramatically reduce response times and development cycles. However, network troubleshooting still accounts for a significant amount of NetOps engineering time, and needs to be optimized with agile platform strategies. Continuous network automation and validation are designed to simplify network operations to increase speed and efficiency, improve availability, and foster agility and innovation. Today's digital enterprise must be more agile than ever to keep pace with customer expectations.
