A single melody can be beautiful, but a symphony is made of many.

Cloud-native applications, known as CNA 1.0 in this book, typically operate on well-architected platforms with decentralized management. However, they are precisely ruled by GitOps-enabled policies and manifests. Consider the performances of the Berlin Philharmonic in the Berlin Philharmonie Hall under the baton of Sir Simon Rattle. It’s not uncommon for a few players to be absent on any given night, substituted seamlessly ...
