Top 6 Java Frameworks to build Microservices in 2023 - Best of Lot
Hello Java Programmers, if you are thinking about Microservice Architecture and Cloud-Native development in Java and exploring options like frameworks, libraries, and technologies then you have come to the right place. Earlier, I have shared the best Microservice courses, and Microservice design patterns and in this article, I am going to share the best Microservice Framework for Java developers. While you may know that Spring Boot and Spring Cloud is the leading framework for developing Microservice applications in Java, there are a couple of more options as well like MicroNaut, DropWizard, and Quarkus IO. In this article, you will learn about the top 5 frameworks you can use to develop Microservice in Java.
What are Microservices? Why use Microservice Architecture?
When you search for Microservices on the internet, you will find a lot of different definitions, some of them are too technical and some of them are too easy to describe what is Microservice.Before going to Microservices, let's take a step back and try to understand the evolution of application architecture and what caused the development of Microservices in the software development world.
Long back there was a time when we just maintain one application, one code-based, and they are also deployed into each machine.
People realized this and they created best practices to divide code into different modules. The idea is that each module should be independent of each other so that you can develop, test, and deploy them separately, and Web applications are born.
This evolution continues on the server-side as well and people started breaking down a big monolithic application into multiple standalone, independent smaller applications, or should I say micro applications.
The architecture where we have multiple Micro applications providing different services connect to each and perform as one application is known as Microservice architecture.
Now, you might be thinking what is the benefit of it? Well, these Microservices are very small as compared to Monolithic applications which means you can develop, test, and deploy them quickly and independently. This really improves the delivery and release cycle.
It also makes a distributed architecture where you can deploy Microservices on a different host or same host, this means better utilization of server resources like storage, memory, and CPU. And, finally, it also helps with scalability as you can quickly spawn new instances of the service whose demand is increasing.
For example, let's think about Amazon Prime Day when a lot of people shop and traffic to the Amazon site increases, at that point you need more processes to handle those checkouts, so you will create new instances of those processes but you don't need to scale other services which are not prime related, like services which are indexing Amazon products.
6 Framework to build Microservices and Cloud Native Java Development in 2023
So, this was my explanation of Microservices in general. As I have said, this may not be accurate or technically correct, but this is what you will see in most the places where a Microservice architecture is actually implemented.Now that we know what is Microservice and what are its benefits, let's explore a couple of Java frameworks that can help you to develop Microservices in Java.
1. Spring Boot + Spring Cloud
There is no doubt that Spring Boot together with Spring Cloud is the best option for developing Microservices in Java. It's the most established and tested framework and you will find a bigger community to support you when you are stuck.Apart from up-to-date and in-depth documentation, there are also a lot of resources available online when it comes to learning Spring Boot and Spring Cloud, like Spring Boot Microservices course on Udemy which can get you started in no time.
Now coming towards feature, Spring Cloud provides many features out-of-the-box which are needed in a Microservice architecture like service discovery and load balancing. It follows Netflix Microservice architecture, which is also the most common implementation.
2. QuarkusIO
Quarkus is another full-stack, Kubernetes-native Java framework made for Java virtual machines (JVMs) and native compilation, optimizing Java specifically for containers and enabling it to become an effective platform for serverless, cloud, and Kubernetes environments.3. MicroNaut
This is another modern, JVM-based, full-stack framework for building modular, easily testable microservice and serverless applications. Micronaut is getting a lot of love from the Java community and with big companies like Oracle and JetBrains putting their weight behind MicroNaut may emerge as a strong contender to Spring Boot and Spring cloud in near future.When it comes to technical things, there is a key difference between MicroaNaut and Spring Framework, Spring which relies exclusively on runtime reflection and proxies, Micronaut uses compile-time data to implement dependency injection.
Another interesting thing to know about MicroNaut is that it's created by OCI, the same company that created Grails, a popular web development framework for Groovy developers.
4. DropWizard
DropWizard is another powerful framework for creating RESTful web services and microservices. It uses popular Java libraries like Jetty, Jackson, and Jersey for creating high-performance Java applications quicker and easier.5. MicroProfile
Eclipse MicroProfile is an initiative to optimize Java EE for Microservice architecture. It aims to provide a vendor-neutral specification to create Microservices architecture by leveraging Java EE. The specification has been created by experts and backed by organizations like IBM, RedHat, and Oracle, which makes it great to use for Microservice development and deployment.6. Eclipse Vert.x
Vert.x from Eclipse is a lightweight framework to develop Reactive Microservices. It supports a non-blocking and asynchronous development model and allows you to run your distributed application runs on top of a Java Virtual Machine.Other Java and Programming Articles you may like
