10 Best Java Frameworks For Microservices 2023

by karthik Updated: Dec 20, 2022

Microservices break down complex applications into smaller and independent services. Microservice architecture provides solutions to difficulties of using Monolith architecture, such as scalability and numerous lines of code for applications. The benefits are typically divided by business domain, allowing developers to focus on a specific part of the application and iterate on it quickly. Applications can be changed, deleted, and replaced without affecting the entire application, making application maintenance simpler.

 

Java Microservices Libraries are a set of open-source libraries that empower developers to quickly and easily create microservices-based applications. They provide tools and frameworks for creating and managing microservices, including APIs, distributed systems, and cloud-native architectures. Each service performs a specific task, such as handling user authentication, providing data storage, or processing payments. They help developers easily create distributed applications without having to write complex code. They give us a way to quickly identify and debug any issues that may arise in a distributed system. By using microservices in Java, new technology and process adoption become easier. 

 

Java Microservices rely on a communication protocol called Remote Procedure Call (RPC) to facilitate communication between services. RPC is a robust protocol that allows for the remote execution of procedures or functions without the need for shared memory or database connections between services. This makes it an ideal solution for distributed systems, as it allows for efficient communication between multiple services without requiring them to be co-located. RPC also allows easy integration of new services into an existing system without requiring changes to the current system.

 

Each Java Microservices Library has its unique set of features and functionalities. light-4j, piggymetrics, Activiti, microservices-spring-boot, mycollab, and microservice-istio are libraries that help us to reuse the code. Micronaut is a full-stack framework for creating JVM-based applications. Apache Camel is an open-source integration framework that provides components for routing messages. Quarkus is a Kubernetes-native Java stack designed to make applications more efficient. Helidon and KumuluzEE are lightweight frameworks for creating serverless applications.

 

Check out the below list to find the best top 10 Java Microservices Libraries for your app development.
