"In Part two, we examined secure by design principles, with a approach, secure access service edge (SASE), and quantum-safe planning becoming non-negotiable foundations for the next decade. Automation is another pivotal strand to the change that's taking place. Instead of relying on manual command-line interfaces (CLI), tomorrow's networks will be defined by code, workflows, and application programming interfaces (APIs). From infrastructure as code (IaC) and observability to evolving skillsets, automation is not just about efficiency - it is becoming the DNA of modern networking."
"Infrastructure as code has long been a staple in cloud computing but its adoption in networking is still maturing. Patricio Martelo, director of network solution architecture at Alcatel-Lucent Enterprise, says that while "IaC for networks is maturing at a rapid pace, it is not widely adopted outside of cloud environments". He explains that networks don't always have the same dynamic, on-demand nature as cloud workloads, so many organizations selectively adopt IaC in provisioning, compliance auditing, or remediation, but not yet in continuous operations."
Agility in connectivity is being achieved through programmability and automation, reshaping how people, applications, and data connect. Cloud-native networking uses service meshes, APIs, and open standards to build and scale distributed applications. Secure-by-design principles, including secure access service edge (SASE) and quantum-safe planning, are becoming foundational. Networks are shifting from manual CLI operations to code, workflows, and APIs, with automation spanning observability and evolving skillsets. Infrastructure as code is redefining network build processes but remains unevenly adopted outside cloud environments. Skills gaps, legacy systems, and lingering mindset shifts constrain broader IaC and continuous operational adoption.
