Spring boot Vs Vert.x

Reading Time: 5 minutes

So we’re going to discuss the two greatest frameworks which are in the trend i.e. We’re going to see the comparison between the Spring-Boot and VertX.

Spring Boot designed to get developers up and running as quickly as possible, with the minimal upfront configuration of Spring. Spring-Boot takes an opinionated view of building production-ready applications. Make implementing modern application best practices an intuitive and easy first practice! Build microservices with REST, WebSocket, Messaging, Reactive, Data, Integration, and Batch capabilities via a simple and consistent development experience.

Vert. x an open-source, reactive, and polyglot software development toolkit from the developers of Eclipse. Reactive programming is a programming paradigm, associated with asynchronous streams, which respond to any changes or events.

What is Vert. X ?

Vert. x is a toolkit, we can embed it into our standalone Java application. We can use it by instantiating the object of Vert. X and calling the method on it. In toolkit mode, our code control vert. X.

The installation of vert. x is quite simple. It distributed in a zip file having a bunch of Jar files. We simply unzip the file and add all the JAR files to the classpath of our Java application. After adding all the JAR files, we are ready to use Vert. X in our application.

What is Spring-Boot?

Spring Boot provides a good platform for Java developers to develop a stand-alone and production-grade spring application that you can just run.

It gets starts with minimum configurations without the need for an entire Spring configuration setup.

Advantages −

Easy to understand and develop spring applications.

Increases productivity and reduces the development time.

History of Vert. X :

Vert. X was started by Tim Fox in 2011 while he was employed by VMware.

Fox in the starting named the project “Node. x”.The naming of Node.js with the “x” representing the fact that the new project was polyglot in nature. And didn’t simply support JavaScript.

 New name play on name node, as a vertex a synonym for a node in mathematics.

In December 2012, after he left their employment, VMware served legal papers on Tim Fox to take control of the Vert. X trademark, domain name, blog, GitHub account, and Google Group from the Vert. x community.

In January 2013, VMware persuaded. That would be in the best interests of Vert. X community to move the project and associated IP to the Eclipse Foundation, a neutral legal entity.

In August 2013, the core Vert. X project completed its move to the Eclipse Foundation.

In May 2014, Vert. X won the award for “Most Innovative Java Technology” at the JAX Innovation Awards.

On January 12, 2016, Tim Fox stepped down as the leader of the Vert. X project. and Julien Viet, a long-time contributor, took his place.

History of Spring-Boot:

The first version was written by Rod Johnson. He released the framework with the publication of his book Expert One-on-One J2EE Design and Development in October 2002.

The framework was first released under the Apache 2.0 license in June 2003. The first production release, 1.0 in March 2004.

 Spring 2.0 released in October 2006, Spring 2.5 in November 2007, Spring 3.0 in December 2009, Spring 3.1 in December 2011, and Spring 3.2.5 in November 2013.

Spring Framework 4.0 was released in December 2013. Notable improvements in Spring 4.0 included support for Java SE (Standard Edition) 8, groovy 2, some aspects of Java EE 7, and the WebSocket.

Spring Boot 1.0 was released in April 2014.

Spring Framework 4.2.0 was released on 31 July 2015 and was immediately upgraded to version 4.2.1, which was released on 01 Sept 2015. It is “compatible with Java 6, 7, and 8, with a focus on core refinements and modern web capabilities”. Framework 4.3 released on 10 June 2016 .

It will be the final generation within the general Spring 4 system requirements (Java 6+, Servlet 2.5+), […]”.


There no framework that the best for each and every use case. Vert. X is a good choice for an event-driven microservice architecture that can handle many parallel requests in a resource-efficient way.

From a developer experience point-of-view, working with Vert. x was an enjoyable challenge. Requires a change in mindset from Spring Boot development,.

The documentation and resources well put together, and the intuitiveness and consistency of the framework made it easy to work with.

It would be interested in applying Vert.x to a situation with a large volume of data points to process.Based on how Vert. x gracefully handled heavy load, it would be interesting to evaluate Vert. x against other options in a similar manner.

Implimentation comparision:

The flow the Spring Boot application pretty straightforward and can be captured by the simplified Kotlin snippet from the web and service layers.

A lot of the details were removed, all the blocking operations depicted. Each request runs on a single thread making the code pretty straightforward to step through and to understand for anyone looking at it for the first time.

The Vert. X code, as expected, looks quite a bit different. Let’s start with the scanning verticle. If you familiar with Node and Express. the structure of the code may look familiar. At the top of the start() method we assemble the HTTP router and its callbacks. Within the handler for the scanning endpoint. We start evaluating the outcome of the scan (accept/reject), save the outcome. The start() method ends with the logic required to create the HTTP server on port 8080.


Vert. X uses low-level IO library Netty.

The application framework includes these features:

Polyglot. Application components are written in Java, JavaScript, Groovy, Ruby, Scala, Kotlin, and Ceylon.

Simple concurrency model. All code single-threaded, freeing from the hassle of multi-threaded programming.

Distributed event bus that spans the client and server-side.

example of spring-boot:


Spring Boot offers some tools for reactive programming. But they just added to the existing Spring framework (since version 5). As , Vert. X completely rooted in the reactive concept, which makes it feel much more natural and consequent for me to implement reactive code in Vert. x.
