Day 1: Bootstrap and Lifecycle.

Welcome to the first lesson of our journey into building hyperscale microservices. Today, we're diving deep into something often taken for granted: the very moment your Spring Boot application comes to life, and how it gracefully exits. This isn't just academic; understanding the bootstrap and lifecycle of a Spring Boot application is fundamental to building robust, resilient, and efficiently scalable systems that can handle hundreds of millions of requests per second. Think of it like the launch sequence of a rocket. Every stage, every ignition, every separation must happen precisely, or the entire mission fails. Your microservice is no different. Its startup and shutdown sequences, if not meticulously managed, can lead to cascading failures, resource leaks, and unpredictable behavior in a distributed environment.
