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

# Problem statement

Let's consider an online auction website where users can log in and participate in available auctions.

We need to inform the users of the bid price change (when a new bid is offered) via WebSocket to ensure real-time communication.

We’ll also need an API to handle items, auctions, and persons. The API will also provide the ability to open and close new auctions.

Let's consider the below diagram:
