Learn about the best microservices framework in this comprehensive and informative article. Find out their strengths to choose the best one for your needs.

 

Microservices architecture is favored for building distributed applications composed of small, independent, and loosely coupled services. They offer many benefits. However, developing microservices also poses some challenges, such as complexity, coordination, testing, and monitoring. Therefore, you need a microservices framework.

 

But what is a microservices framework? It’s a set of libraries, tools, and standards that help you to create, deploy, and manage microservices. With a plethora of frameworks available, choosing the right one can be daunting. To help navigate this landscape, we’ll explore the top 10 choices and their key features.

Spring Boot with Spring Cloud

 

 

Spring Boot is a widely used Java framework that is handy for developing microservices. It offers a range of extension projects under Spring Cloud, allowing you to quickly build full-stack microservices. 

 

Spring Boot’s biggest advantage is that it enables the creation of large-scale systems by starting with a simple architecture with several collaborating components. Therefore, whether it’s a small- or large-scale system that needs to be built, Spring Boot is the way to go. Additionally, the framework’s Inversion of Control ensures seamless integration with other popular frameworks.

 

Key features:

  • Spring has various modules to easily integrate with popular databases. 
  • Spring Boot can be easily integrated with Resilience4J. It provides multiple functionalities to handle failure in distributed systems.
  • Spring has capabilities to build reactive apps. It is super easy to make REST APIs with the help of Spring MVC. 
  • Spring is easy to integrate with MQ to create asynchronous-style services. It also has a module to build SOAP-based applications.
  • With the help of various modules, Spring provides an abstraction to integrate with Apache Kafka, AMQP, RabbitMQ, and ActiveMQ.

 

Eclipse Vert.x

 

 

Vert.x is a popular microservices framework from the Eclipse foundation. It’s one of the best frameworks for microservices in Python. Nonetheless, it supports other languages, including Java, Kotlin, JavaScript, Ruby, Groovy, Scala, and Ceylon. As a result, it is the perfect choice for organizations with developers of different skill sets. 

 

Eclipse Vert.x is a versatile toolkit that enables you to build reactive microservices. It is designed to be event-driven and non-blocking, which means that your application can handle a high volume of concurrency using only a small number of kernel threads. With Vert.x, your application can scale with minimal hardware requirements.

 

Key features:

  • Vert.x core is around 650 kB in size.
  • You can use Vert.x core as a standalone library. Or you can use any of the many modules available to extend its functionality. For example, there are modules for application development, database access, messaging, clustering, service discovery, circuit breakers, and more.
  • Vert.x follows the Reactive Manifesto principles and provides a reactive programming model based on callbacks, futures, promises, and streams.
  • Vert.x supports clustering, service discovery, and distributed event bus, which allow you to build fault-tolerant and scalable microservices.
  • Vert.x doesn’t impose any specific architecture or design pattern on your application. You can use it to build monoliths, microservices, or anything in between.

 

Dropwizard

 

 

Dropwizard is a comprehensive framework that allows developers to create high-performance and RESTful web services that are easy to maintain. It leverages several mature Java libraries—including Jetty, Jersey, Jackson, Metrics, and Hibernate—to provide a cohesive and user-friendly platform for building microservices. 

 

By combining these libraries, Dropwizard streamlines the application development process and provides a powerful toolset for creating ops-friendly web services.

 

Key features:

  • Dropwizard configures your application using YAML—which is easy to read and write.
  • Dropwizard uses SLF4J and Logback for logging and provides sensible defaults for formatting and rotation.
  • Dropwizard integrates with Metrics—a library that offers various metrics, such as counters, gauges, histograms, timers, etc.—to measure the performance and health of your application.
  • Dropwizard provides testing utilities—such as ResourceTestRule and DropwizardAppRule—to help you write unit and integration tests for your application.
  • Dropwizard supports relational databases via Hibernate and JDBI and provides connection pooling, migrations, validations, and more.

 

Restlet

 

 

Restlet is an excellent tool for Java developers who want to create microservices following the REST architectural style. This framework is divided into a lightweight RESTful web framework and a robust REST client engine. It’s versatile enough to support both server-side and client-side development. It can operate on any Java platform, including Java SE, Java EE, Google App Engine, and Android.

 

Key features:

  • Restlet Framework models your application as a set of resources, each with a unique URI, and supports the standard HTTP request methods.
  • It allows you to manipulate different representations of your resources and provides converters, parsers, and writers to handle them.
  • Restlet Framework uses annotations, such as @Get, @Post, and @Put, to map your resource methods to HTTP request methods and specify the expected and produced representations.
  • Restlet Framework uses components like Server, Client, Router, and Filter to assemble your application and provides a fluent API to configure them.
  • Restlet Framework offers various extensions to integrate with other popular frameworks and technologies.

 

Helidon

 

 

Helidon is a set of Java libraries developed by Oracle used to write microservices. It supports imperative and reactive programming styles and comes in two flavors: Helidon SE and Helidon MP. 

 

Helidon SE is a lightweight and functional framework that gives you complete application control. On the other hand, Helidon MP is a declarative and standards-based framework that adheres to the MicroProfile specifications.

 

Key features:

  • Helidon provides a configuration API that supports various sources and formats.
  • It has a web server API that supports both blocking and non-blocking IO, allowing you to create routes, handlers, filters, and more.
  • Helidon offers a security API that supports authentication, authorization, auditing, identity propagation, etc. and integrates with popular providers.
  • Its metrics API supports HTTP endpoints for various metrics, including counters, gauges, histograms, and timers.
  • Helidon provides a health check API that allows you to define and register health checks and expose them via HTTP endpoints.

 

Micronaut

 

 

Micronaut is an up-to-date JVM-based framework that offers a full-stack solution for creating modular, easily testable microservices and serverless applications.
