Mastering Microservices with Spring Boot and Spring Cloud Training

4 Days

Description

Rapid advancements in cloud-based software delivery and virtualization have caused many developers to question the wisdom of a “Big Server” approach to deploying web applications. Spring Boot is a technology stack that builds on the popular Spring Framework to allow Spring-based applications as stand-alone jar files that host their own web servers. This approach works nicely with deployment automation and rapid scaling.

Cloud-based, highly-distributed applications face additional challenges in supporting a dynamic environment – especially around configuration, service discovery, service resilience and monitoring.  Spring Cloud embraces and extends the popular suite of open source cloud tools published by Netflix (Eureka, Hystrix, Ribbon, etc).

This course introduces Spring Boot, Spring Cloud and the Netflix OSS suite as a way of deploying highly resilient and scalable RESTful services and web applications.

Audience

Java developers preparing to write and - or support back-end server applications using the Spring framework.
