Spring Boot and Cloud Native Applications

Spring Boot is a popular Java-based framework that significantly simplifies the development of cloud-native applications. By providing auto-configuration, embedded servers, and an opinionated approach to dependencies, it enables developers to rapidly create stand-alone, production-ready microservices. These microservices serve as the fundamental building blocks of a cloud-native architecture, designed to be packaged in containers, deployed independently, and managed by orchestration systems like Kubernetes. This synergy allows for the creation of highly scalable, resilient, and maintainable systems that fully leverage the dynamic and distributed nature of modern cloud computing environments.
