java microservice Course Overview
This Java microservices course covers fundamental concepts of microservices architecture, utilizing Spring Boot framework. Topics include:
- Introduction to Microservices
- Java Basics Review
- Spring Boot Introduction
- Building RESTful Services with Spring Boot
- Service Discovery and Registration. Students will learn to design and implement RESTful APIs, utilize Spring Data JPA for database interactions, and manage service discovery. The course emphasizes practical application through hands-on projects and real-world examples. By the end, participants will have the skills to develop scalable and resilient microservices using Java and Spring Boot.
Key Highlights
Containerization
Microservices are often deployed using containerization technologies like Docker and managed with orchestration tools like Kubernetes. These technologies enable easier deployment, scaling, and management of microservices
Security
Securing microservices involves various aspects like authentication, authorization, and data protection. Frameworks like Spring Security and tools like OAuth are commonly used to implement security measures in microservices
Deployment Strategies
Microservices can be deployed using various strategies like blue-green deployment, canary releasing, and rolling updates. These strategies help minimize downtime and risk during deployments
RESTful APIs
Microservices communicate with each other and with clients via lightweight protocols like HTTP, typically using RESTful APIs. This enables loose coupling between services and allows for easier integration and scalability
Tools Covered
Spring Boot
Grafana
Kubernetes
Prometheus
Go
AxonIQ
Skills Covered
Java Programming: A strong understanding of Java programming language is essential as microservices are often implemented using Java frameworks like Spring Boot, Dropwizard, etc.
Database Management: Microservices often have their own databases. Understanding how to manage databases within the context of microservices, including data consistency and transaction management, is important.
3. Testing: Implementing unit tests, integration tests, and end-to-end tests for microservices is crucial to ensure their reliability and functionality.
4. API Gateway: An API gateway is often used to provide a single entry point for clients and to handle tasks like authentication, routing, and monitoring. Spring Cloud Gateway or Netflix Zuul are popular choices.
