As cloud technologies evolve, so do the requirements for cloud networking. Now, it’s time for an entirely new architecture for networking in the public cloud. The Shared Service Architecture for DevOps Consider the evolution of Amazon Web Services (AWS). In 2006, AWS started with EC2 Classic where there was not much networking to do: an EC2 instance either has a public IP address or a 10.0.0.0/8 network.

Granting access control to who can access what information becomes an important IT/Ops task.
