Day 87: Blue-Green Deployment for the Core – The Art of Seamless Financial Transitions

Updating a core banking system is like performing an engine swap while the car is moving at 200 mph. In this video, we go beyond the DevOps basics of Blue-Green deployment to explore how it functions at hyperscale (100M+ RPS).

We cover:

Why rolling updates are dangerous for stateful financial ledgers.

The architecture of a Traffic Router vs. a standard Load Balancer.

The "Expanding and Contracting" pattern for zero-downtime database migrations.

Implementing instant rollbacks to mitigate financial risk.

A hands-on Java demo using simple HTTP services and socat to simulate a live cutover.

Whether you're a Senior Architect or a Backend Engineer, this guide provides the blueprint for building "Five-Nines" (99.999%) reliable financial infrastructure.
