Cloud and multicloud are having a significant impact on the future of network control. Managing pools of infrastructure as a cohesive collection of fungible resources requires more changes to operations than to the underlying devices.
One of the best things about the newly launched NRE Labs is that it’s not just focused on configuration management. The ability to automate changes to network configuration is a vital part of any network automation initiative, but far from the complete picture. When constructing the curriculum, we wanted to give equal focus to other aspects of automation, especially those that will end up saving time and effort for the majority of network engineers, many of whom may not change their network very often.
As networking moves from scale-up devices to scale-out networks, the forwarding landscape is converging on a fairly narrow set of silicon options: custom in the core and merchant everywhere else. With cloud and multicloud poised to drive constantly shifting network architectures, it’s a certainty that the industry will see a broad diversification of forwarding architectures in the coming years—a development that will have significant implications on both the economics and physics of networking in the multicloud era.
We at Juniper Networks have been working diligently to launch new ways for Network Engineers to learn about Network Reliability Engineering (NRE). At NXTWORK 2018 in Las Vegas, we announced new training and new websites to help others take the first step in their NRE journey.
Just as networking technology is evolving, so too are the architectures that connect and support applications and services. In today’s IT world, there is no enterprise-wide infrastructure. Rather, there are individual networks—data center, campus, branch, public cloud and WAN—each with their own teams, budgets, priorities and tools. And while these networks are also likely to have their own micro drivers for change, ultimately the evolution of network architectures will be somewhat co-dependent as the industry converges isolated devices into coherently-managed resource pools.
