This document contains a series of tweets by @alexsotob discussing concepts related to microservices, containerization, and DevOps practices like blue-green deployments, canary releases, and dark launches. It includes diagrams illustrating these techniques and quotes from Disney movies to highlight aspects of distributed systems and continuous delivery. The tweets cover topics like microservice architectures, containerization with Kubernetes and Istio, strategies for zero-downtime deployments, handling state, and testing techniques like mirroring and synthetic transactions.
