Building Scalable Microservices with Java and Microsoft Azure

Abstract

As enterprise applications increasingly transition to cloud-native architectures, the combination of Java and Microsoft Azure provides a powerful foundation for building scalable, resilient microservices. This article explores best practices for designing and deploying microservices using modern Java frameworks such as Spring Boot and Quarks in conjunction with Azure services like Azure Kubernetes Service (AKS), Azure App Services, and Azure API Management. It examines architectural strategies that support scalability, including event-driven design, statelessness, and container orchestration. Emphasis is placed on integrating CI/CD pipelines, enhancing observability with Azure Monitor and Open Telemetry, and implementing robust security using Azure Key Vault and Azure Active Directory. A real-world case study demonstrates the practical application of these principles in migrating a legacy monolithic application to a scalable microservices architecture on Azure. By synthesizing cloud engineering methodologies with Java’s mature ecosystem, this article provides valuable insights for developers, architects, and DevOps professionals seeking to leverage Azure for cloud-native Java applications. The work concludes with forward-looking perspectives on emerging technologies, including serverless microservices and edge computing, positioning readers to make informed design decisions in evolving cloud environments.
