Spring Architecture and Design

Course Description

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
