Description

Spring Boot Microservices

Introduction

Welcome to the Spring Boot Microservices training program! This course is designed to provide you with a comprehensive understanding of developing and managing microservices using the Spring Boot framework. You will learn how to build scalable, resilient, and maintainable microservices-based applications while applying best practices in distributed system design, deployment, and monitoring.

Objectives:

By the end of this training, participants will be able to:

• Understand the fundamentals of microservices architecture.
• Develop microservices using Spring Boot.
• Implement RESTful APIs and communicate between microservices.
• Handle security, configuration management, and service discovery.
• Deploy and monitor Spring Boot microservices in production environments.
• Implement resilience and fault tolerance in microservices.

Target Audience:

• Java developers looking to transition from monolithic to microservices architecture.
• System architects aiming to design scalable, distributed systems.
• DevOps engineers who want to understand microservices from a development perspective.

Prerequisites:

To get the most out of this training, participants should have:

1. Basic knowledge of Java programming: Familiarity with Java SE is necessary.
2. Experience with Spring Framework: Basic understanding of Spring Core (IoC, DI) and Spring MVC.
3. Familiarity with RESTful services: Knowledge of creating and consuming REST APIs.
4. Understanding of Maven/Gradle: Experience in project building and dependency management.
5. Basic understanding of Docker and containers (for advanced sessions).
