Quarkus is a modern Java framework that simplifies the creation of web applications. With the help of Quarkus, you can create modern applications and deploy them easily on the cloud.

You’ll begin the course with an introduction to Quarkus and the different features that make it a great Java framework. Next, you’ll explore the basics of Quarkus, such as creating and configuring an application, adding plugins, and testing your code. You’ll learn how to build modern web applications using Quarkus by creating and consuming REST endpoints and documenting them. You’ll also learn how to create a WebSocket server and a GraphQL endpoint and ensure fault tolerance for your application. Lastly,  you’ll add different kinds of database connections to your Quarkus application.

After completing this course, you’ll be equipped to create various applications and microservices using Quarkus, a must-have knowledge for any developer.

Developing Microservices with Quarkus

# Introduction

**Dependency injection** refers to the process of passing a dependency to other objects (beans) or frameworks. Quarkus simplifies this process, allowing developers to concentrate on the business logic rather than worrying about how to structure their application to use different objects.

# How Quarkus handles it

In a Quarkus application, a **bean** is a container-managed object, which means we don’t have control over its life cycle.

Here is an example of a bean:
