Orchestration
ELI5 — The Vibe Check
Orchestration is the process of automatically managing, coordinating, and scheduling where your containers run. Just like a conductor coordinates an orchestra to produce music, container orchestration coordinates hundreds of containers across many machines to keep your app running perfectly.
Real Talk
Container orchestration automates the deployment, scaling, networking, and lifecycle management of containers across a cluster. Kubernetes is the dominant orchestration platform. It handles scheduling, self-healing (restarting failed containers), horizontal scaling, rolling updates, and service discovery.

Service Mesh
In a microservices system, every service needs to handle retries, timeouts, mutual TLS, and send traces. You could code all that in every service.
