Course architecture
Introduction
Bounded contexts as a prerequisite for micro-services architecture.
Stateless operation to promote horizontal scalability.
Types of deliverables: stand-alone application or serverless function.
Data sovereignty.
Communication between micro-services.
Testing.
Putting it into practice: refactoring a monolithic application into micro-services.
Service discovery with Spring cloud Netflix
Service discovery: introducing the concept.
The role of the Eureka server.
Self registration and self unregistration operations.
Registry propagation.
Health checks as a means of keeping the registry up to date.
Implementing load balancing.
Requesting an application with RestClient.
Practical application: getting to grips with a Spring application (data access, REST API, testing).
Publish / subscribe with the brokerApache Kafka
The role of the broker in a micro-services architecture.
Introducing Kafka.
Subscribing to a topic.
Sending messages to a topic.
Putting it into practice: asynchronous communication between micro-services with Kafka and spring-kafka.
Exposing microservices with Spring cloud API Gateway
The API Gateway as an entry point to a set of micro-services.
Routing rules.
API Gateway action on requests and responses (retries, security, etc.).
Data aggregation.
Putting it into practice: creating an API Gateway with Spring Cloud Gateway to expose the micro-services developed above.
Centralizing configuration with Spring Cloud Config
The role of a config server.
Storing and protecting properties.
Property encryption methods.
Coupling with a Eureka Server.
Declaring a config server in client applications.
Putting it into practice: creating a config server with Spring cloud Config, coupling micro-services with it.
