Course Overview:
Spring Cloud is a platform for building Java-based distributed systems and microservices. Building complex enterprise applications is challenging. Any change made to a part of the systems could trigger the need for changing the design of the entire system. By the end of this training, participants will have a solid understanding of Service-Oriented Architecture (SOA) and Microservice Architecture as well practical experience using Spring Cloud and related Spring technologies for rapidly developing their own cloud-scale, cloud-ready microservices.
Course Objectives:
- Participants will learn how to evaluate different technologies and approaches for the design of a services-based system architecture.
- The training begins with a discussion and comparison of monolithic systems and service architectures, then digs into the details of microservice architecture.
- Participants are given a chance to put their knowledge into practice as they step through the creation and deployment of a set of proof-of-concept microservices built with Spring Cloud, Spring Boot and Docker.
- Finally, the relevant infrastructure building blocks are examined to help participants determine the most suitable tools and approaches to use for different organizational requirements.
- Part lecture, part discussion, exercises and heavy hands-on practice
