By November 30, 2023December 12th, 2023No Comments
Spring Boot vs Quarkus

In the ever-evolving landscape of Java development, the popularity and vitality of the language persist. Developers always discuss Spring Boot vs Quarkus for Java Application development. Despite speculation about the retirement of Java, it remains a formidable choice for developers, continually evolving with the advent of third-party frameworks.

The contemporary shift towards microservices architecture has fueled the prominence of microservices frameworks, with Spring Boot vs Quarkus emerging as prominent choices for building cloud-native Java applications.  

In this discussion, we delve into a detailed comparison of Spring Boot and Quarkus, examining their feature sets, performance metrics, development costs, market popularity, and other critical aspects. 

Spring Boot Overview 

When we discuss Spring Boot vs Quarkus, Spring Boot has become a cornerstone in the development of web applications, offering a streamlined approach to building stand-alone, production-grade Spring-based applications.

With minimal Spring configuration requirements, developers can produce maintainable code efficiently. Spring Boot’s ease of use and compatibility with popular frameworks and libraries make it a preferred choice for many developers. 

Quarkus Introduction 

When we discuss Spring Boot vs Quarkus, Quarkus stands out as a Kubernetes-native Java framework designed to develop and deliver small artifacts. With a focus on faster boot times and lower request times, Quarkus is optimized for serverless, cloud-native environments.

Quarkus integrates seamlessly with Java frameworks, libraries, and environments such as Eclipse Micro profile, Spring, Kafka, and Hibernate, offering a unified reactive and imperative programming model. 

Noteworthy Quarkus Features 

Quarkus presents several compelling features for developers. Its compact framework, live reload capabilities, and support for the repository pattern with Panache are particularly noteworthy. Version 2.0 introduces live reload for unit tests, enhancing the test-driven development (TDD) experience.

When we compare Spring Boot vs Quarkus features and functionalities, all of them are great and beneficial for developers to create something new and really essential while developing a Java app. 

What do I like about Quarkus when Comparing Spring Boot vs. Quarkus? 

As a developer, it has a few remarkably interesting things. Besides the unified configuration, Quarkus is a very compact framework, and it comes with many integrations (via extensions) to many frameworks and libraries.  

As we compare Spring Boot vs Quarkus, I like that I do not need to depend on a particular IDE to write code and have this nice live reload for the application.

But from version 2.0, the live reload also applies to the unit tests by automatically running the tests that are associated with the code under modification, making TDD an amazingly easy integrated experience.  

Secondly, while comparing Spring Boot vs Quarkus, what I like about Quarkus is that it offers the same patterns I am used to with Spring.

For instance, when working with persistence and using JPA with Hibernate, I like to use the repository pattern, which helps abstract the code with Spring Data. Quarkus also implements the repository pattern with Panache, but, in addition, it adds the Active Record pattern.  

Spring Boot vs Quarkus 

Feature  Quarkus  Spring Boot 
Dependency  Uses CDI. Implemented with only a subset of CDI features currently.  Uses robust Dependency Injection Container 
Data Persistence  Uses familiar frameworks such as Hibernate – more innovative  Based on Spring Data abstraction, it is more mature. 
Application Boot-Time  Fast boot times  Slower boot times than Quarkus – generally slower than projects derived from Java Enterprise due to abstraction from the top of the Spring framework 
Memory Consumption  Lower memory consumption on boot and under heavy load   Higher memory consumption compared to Quarkus 
Maturity  New framework – documentation, and community less active than Spring Boot  It is much more mature, open-source, and feature-rich. Excellent documentation and community support
