Overview
This 3-day course on Spring 4.x and Microservices provides an in-depth knowledge on the basics of Microservices and understanding of Spring in context of Microservices. The course provides a deep dive into developing Microservices, examining the Microservices architectural style and combines it with a dynamic, lab intensive coding environment. This course explores some practical aspects of Microservices, e.g. monitoring, logging, containerizing, deploying and orchestrating Microservices. In addition, students gain insights on the working knowledge of the Spring framework with other technologies.
