Introduction into Quarkus

About the Training

The tech world is constantly reshaping. Where once monolithic applications on powerful servers were the default, the focus has shifted in recent years to microservices: compact, specialized services that form a cohesive whole together and require less powerful hardware. Quarkus is built from the ground up to embrace this cloud-native paradigm, serving as a framework for web and command-line applications. With its emphasis on speed, efficiency, and developer-friendliness, it is the choice for those who want to be ready for the future. With many similarities to Spring Boot, it offers familiar patterns for Java developers, along with innovative features to set it apart.

What does this mean for you as a developer?

• 🚀 Lower Memory Consumption & Smaller Binaries: Perfect for microservices and cloud computing.
• ⚡ Lightning-Fast Startup Times: Leveraging JVM optimizations and native executables with GraalVM.
• ↗️ Scalability: Optimized for cloud-native environments.
• ⚙️ Enhanced Developer Experience: Enjoy features like live reload in DevMode and automatic service integration using DevServices.

Do you want to learn how to develop modern, fast cloud-ready applications? In this practical introductory training, you’ll discover how you can utilize Quarkus to transform your applications into flexible cloud-native solutions.

What will you learn?

In this training, you’ll be introduced to the fundamentals of the Quarkus framework. When do you choose Quarkus? How does this framework differ from, for example, Java EE implementations and Spring Boot? How do Quarkus internals work and what makes it, according to their motto, “supersonic” and “subatomic”? These are questions that will be discussed during the training.

Once you’ve mastered the theory and the core concepts, you’ll gain valuable experience by developing a Quarkus application. Throughout the training, you’ll build an application that interacts with a database via RESTful endpoints, ensuring you’ll apply the learned theory in real-world scenarios. By implementing robust unit and integration tests, you’ll validate its functionality and reliability.

Finally, you’ll containerize your application and transform it into a cloud-native solution, ensuring seamless deployment on platforms like Kubernetes, OpenShift, and others.

Who should attend?
This training is ideal for Java software developers eager to explore Quarkus, regardless of your past experience with Spring Boot or other frameworks. You’ll learn to quickly build efficient, cloud-native applications, regardless of your current experience level.
