Quarkus Cloud Development

The course Quarkus Cloud Development from SpiralTrain teaches participants to develop applications with the Quarkus framework.

Quarkus Intro

The course Quarkus Cloud Development starts with an overview of the essentials of the Quarkus framework. Among other things, Quarkus Dependency Injection, which is based on CDI (Context and Dependency Injection), is discussed. It also provides the correct information to the GraalVM for compilation to native code.

Quarkus Configuration

Next attention is paid to the configuration options of Quarkus applications. This includes configuration parameters, YAML configuration and programmatic configuration.

Rest Services

Quarkus is designed to interoperate with well-known Java standards, frameworks and libraries. The course covers how Quarkus can be used to define and approach JSON Rest Services. Attention is also paid to the Open API.

DataAccess

The support that Quarkus has for Data Access with Hibernate ORM and JPA is also treated. Connection pooling and transactions are covered as well.

Messages

Part of the program of the course Quarkus Cloud Development is messaging between applications. Various messaging patterns and stream processing with Apache Kafka are discussed.

Security

Next attention is paid to Security in Quarkus applications. Implementations of various security mechanisms are treated including JSON Web Tokens and OAuth2.

Quarkus Cloud

Quarkus applications are ideally suited to be hosted in a public cloud or in an internally hosted Kubernetes cluster. It is discussed how characteristics such as fast startup and low memory usage are important to keep hosting costs low.

Monitoring and Extensions

Finally attention is paid to monitoring Quarkus applications with the Micrometer Extension and Prometheus. And also writing extensions yourself is covered.

The course Quarkus Cloud Development is intended for developers who want to learn how Quarkus can be used to develop microservices and serverless applications.

Prerequisite Course Quarkus Cloud Development

Knowledge and experience with Java programming and web technology is required to participate in this course.

Realization Training Quarkus Cloud Development

The theory is treated on the basis of presentations and is interspersed with exercises. Demos are used to clarify the theory. Course times are from 9:30 to 16:30.

Certificate Quarkus Cloud Development

Participants receive a certificate Quarkus Cloud Development upon successful completion of the course.
