From Monolith to Micro-services with Kubernetes
summary
Shows a hands‑on evolution from a monolith to microservices using Kubernetes, Docker Desktop and DigitalOcean for the cluster, deploying Redis and a Flask front end, and performing a rolling (ramped) update from v1 to v2 with replicas increasing from 1 to 4. Covers health checks (liveness and readiness probes), deployment options (recreate, blue/green, canary, A/B), the incremental Strangler pattern, and service connectivity via Service Mesh ideas with Envoy sidecar proxies. Demos hit connectivity limits so visualizations replace full multi‑node runs.
