We stopped clicking buttons in AWS consoles and started writing Terraform files. Yet for a long time, connectivity remained the awkward middle child — often managed through manual CLI commands, static SSH tunnels, or brittle VPN configurations that someone senior had set up years ago and nobody dared touch. As we move through 2026, that era is officially over. The “manual CLI” is dead, replaced by Connectivity-as-Code (CaC). Today, networking is no longer a prerequisite for deployment; it is a programmable component of the application lifecycle itself. Industry analysts confirm it: static architectures, fixed identities, and manual oversight are giving way to systems that
