Microservices Architectures Using Spring Boot: Embracing Containerization and Observability

Abstract

Microservices architecture has revolutionized software development by promoting scalable, flexible, and maintainable systems through the decomposition of applications into independent, loosely coupled services. When combined with Spring Boot, containerization technologies like Docker, and observability practices, organizations can build robust applications that are both efficient and resilient. This paper explores the integration of Spring Boot with containerization and observability, focusing on best practices, architectural patterns, and challenges. It delves into containerization strategies using Docker and orchestration with Kubernetes, emphasizing their roles in deployment and scalability. The importance of observability is highlighted through logging, monitoring, and distributed tracing, alongside the implementation of Continuous Integration and Continuous Deployment (CI/CD) pipelines for automated deployment. Additionally, the paper addresses critical security considerations in microservices architectures, providing real-world examples and data to illustrate the effectiveness of various practices and technologies.
