Network Automation in our career

Automation is an abstraction layer. Abstraction layers mask complexity, but do not eliminate it. Someone will need to build and repair the robots. Is that still network engineering? Yes. Consider the following: Being an “automation expert” is akin to saying you’re a “screwdriver expert.” No one would describe themselves like that. In the same way, automation expertise isn’t helpful by itself. To effectively automate, you need networking expertise. You can’t automate what you don’t understand.
But, and this is also really true for the SPs 🙂
Enterprises move slowly when it comes to adopting new technology. In addition, old technologies have a strange way of never dying. Both of those facts suggest that network engineers will have a role to play for a long time. Truly talented networkers who are also effective communicators will get paid as network engineers for many years to come.

From CCIE to Cloud Network Engineer

An interesting article about moving from enterprise networking space to cloud networking role from Tom Taggart.
  • In the cloud the focus is more on the Workflows and Endpoints, in contrast to network nodes and transit nature of the Traffic.
  • Building blocks are changing from traditional physical (or VM based) appliances and their requirements (e.g.: racks, cables, power outlets, etc.) to software based solutions. The promise here is that the added abstraction layer(s) will remove or hide many of the complex details associated with the old building blocks.
  • The network transport for the Cloud is mainly Internet based (for the Edge), however large players like Google, AWS, Azura are building out a global backbone that is parallel to the global internet backbone. This might provide advantages for traffic related to cloud services between geographic islands. (e.g.: VPC islands)
  • Interaction with Infrastructure functions are possible using many of the client libraries, REST API or CLI-based SDK. Using a single Cloud provider provides uniform management-plane, and opens up the possibilities for an easy Infrastructure-as-code approach.
I would not let go all the IETF RFC’s for now, but the transformation of how we interact with the Network Infrastructure is already changing in the direction what public cloud provides.
