AWS engineer Zak van der Merwe published an in-depth article on the complexities of building scalable control planes. The article explains that the control plane, responsible for recording the 'desired state' and reconciling it with the 'actual state,' is where the hardest problems in distributed systems converge. Drawing on experience with EC2 and DSQL, the author explains why correct architectural decisions determine whether a service can survive its own growth.
