The Cloud's Most Important Layer Is Also the One Nobody Wants to Build

An AWS engineer with nearly 14 years of experience shares hard-won lessons from building control planes for EC2 and DSQL. The control plane—conceptually simple, endlessly difficult—reconciles desired state with reality, and its quiet reliability is the only reason customers never think about failing hardware. The piece covers static stability, state management, scaling failures, and how lessons from EC2 directly shaped DSQL's design. It's a rare inside look at the unglamorous systems that make cloud computing possible.
