This article dissects the Spring Boot startup sequence step by step, showing how a minimal @SpringBootApplication triggers listeners, type deduction, auto‑configuration loading, environment preparation, IOC container creation, bean refresh, and embedded Tomcat launch, with interview‑ready explanations.
This article reviews the entire Spring Cloud microservices series, presents a full technology stack diagram, outlines production‑grade best practices for service decomposition, configuration, remote calls, rate limiting, databases, logging and monitoring, lists common pitfalls, offers performance‑tuning tips, discusses the pros and cons of microservices, and points to future directions such as service mesh, serverless and cloud‑native adoption.
This article explains why traditional deployment is problematic, then walks through building Docker images, composing services with Docker‑Compose, deploying to a Kubernetes cluster, setting up CI/CD pipelines, and addressing common pitfalls such as slow starts and service discovery failures.
The article outlines how to create a functional food‑delivery system for a graduation project by focusing on a core transaction loop, detailing user, merchant, and admin modules, and explaining why the rider side is intentionally limited to keep the project manageable.
