Prerequisites
Knowledge of Java.
Practical details
Teaching methods
To optimize the learning experience, e-learning modules can be provided before and after the classroom session or virtual class, at the participant's request.
Course schedule
1 Programming in Java - Pre-training digital learning content
- Introduction to Java and the development environment.
- Types, variables and operators.
- Control structures.
- Methods and best practices.
- Putting it into practice.
Digital activities
This online training course introduces the basics of the Java language and teaches you how to write your first programs. Participants will learn about instructions, types, variables and operators, as well as control structures such as if, switch and loops. They will also see how to use the Eclipse IDE to develop in Java and implement good programming practices. The course concludes with demonstrations and a practical exercise to put the concepts covered into practice.
2 Introduction to microservices
- Definition and perspective.
- Comparison with other architectures.
- Agility, DevOps: practices that promote microservices.
- Benefits but new challenges.
Hands-on work
Definition puzzle.
3 Frameworks and microservices architectures
- Independence and reduced scope.
- Synchronous and asynchronous communications.
- Formalization of interface contracts.
- Design issues.
- The main frameworks available.
Hands-on work
Implementation of a first microservice on a Java framework.
4 HTTP/Restful and GraphQL communication
- REST principles.
- Let's use Jakarta RESTful.
- GraphQL contributions.
- Endpoint documentation (Open API).
- Customer side.
- Security and authentication.
- Implement "Long Running Action".
Hands-on work
Defining and demonstrating web services (REST and GraphQL).
5 Message-oriented communication
- Benefits and main difficulties.
- How to manage transactions
- The Saga pattern.
- Asynchronous communication (ActiveMQ, Kafka...).
Hands-on work
Implementation of asynchronous communication with Kafka.
6 Fault tolerance
- The principle of resilience.
- Why is this important?
- Defensive programming.
- Circuit breaker, Bulkhead.
- Other patterns.
Hands-on work
Pattern implementation "fault tolerance".
7 Deploying and securing microservices
- Introducing Docker.
- Images and containers.
- Service supervision (healthcheck, metrics and logs).
- Safety considerations.
- Cloud offerings, with a focus on Azure.
Hands-on work
Build your own red wire microservice container image.
8 Understanding Docker, getting to grips with containers - Post-training digital learning content
- How Docker works.
- Compiling a Docker image.
- Docker image production features.
- Docker features on Windows.
- Docker in the cloud.
Digital activities
This online training course introduces the fundamentals of Docker and the philosophy of containers in a DevOps context. Participants will learn how to create and manage Docker images, use advanced Dockerfile files and manipulate an image registry. The course also covers network and volume management for data persistence, the particularities of Docker on Windows, and its integration in the cloud.
9 Docker in production, cluster implementation on microservices - Post-training digital learning content
- Presentation of the example application.
- Scaling with Docker Swarm.
- Industrial-level orchestration with Kubernetes.
- Productivity features in Kubernetes.
Digital activities
This online course teaches how to use Docker in a production environment to deploy and maintain complex applications. Participants will learn how to implement a microservices architecture with Docker Compose and Traefik, manage clusters with Swarm, and use advanced orchestration with Kubernetes. The course concludes with best production practices, including rolling updates and monitoring.
