Services that call other services inherit their failures. A slow downstream service starves thread pools. An unavailable one causes cascading failures across the call chain. Here is how to build resilience into service-to-service communication with Spring Boot and Resilience4j.
Read moreSpring Boot adds layers between your business logic and the network — each with overhead that compounds under load. Knowing where each millisecond goes makes optimization systematic instead of guesswork.
Read moreSpring Boot's request processing pipeline adds overhead before and after your business logic runs. Most of it is negligible. Some of it isn't. Here is how to measure each layer and what actually warrants optimization.
Read moreSecurity gaps in Spring Boot applications follow predictable patterns. This checklist covers authentication, authorization, data protection, infrastructure configuration, and the vulnerabilities that survive code review. Work through it before every production deployment.
Read moreSpring Boot offers multiple testing approaches, each loading a different subset of the application context. The choice determines test speed, test scope, and how much infrastructure is required. Here is how to use each correctly.
