Overview

Spring Boot is a platform for building secure and scalable applications that can be deployed independently with an embedded web server. When combined with Spring Cloud, developers can quickly develop robust microservices-based architectures without compromising security or scalability.

This Spring Boot and Spring Cloud with Microservices training course teaches developers how to use Spring Boot, Spring Cloud, and the Netflix OSS suite to deploy highly resilient and scalable RESTful services and web applications.

Objective

  • Create Spring Boot projects
  • Persist data in SQL and non-SQL databases using JPA in Spring Boot
  • Create RESTful services with Spring Boot
  • Deploy services that use Netflix Eureka, Hystrix, and Ribbon to create resilient and scalable services

Training Materials

All Spring Boot and Spring Cloud training attendees receive comprehensive courseware covering all topics in the course.

Software Requirements

• For in-person deliveries, attendees require computers with the Java Development Kit version 8 and an internet connection. Students also require a Java Integrated Development Environment like Eclipse or IntelliJ. We will provide full classroom setup instructions that will include seating in small groups, with supplies such as flipcharts, sticky notes, markers, and pens for the attendees and a projector and Internet connection for the instructor's laptop.

• Online deliveries for this interactive training will use an online meeting platform (such as Zoom, WebEx, GoTo, or Teams) to have face-to-face contact online, including use of breakout rooms for group activities.
