Add to Wishlist

Description

Microservices TrainingDeveloping Microservices 

This five-day DevOps training class is loaded with practical real-world information. From the foremost Service-Oriented-Architecture/DevOps/Agile development training company, comes a course to move the dial on your organizations’ journey with this workshop. You will leave this course loaded with knowledge on the usage of this stack for Microservices. This class combines instructor-led and hands-on lab exercises.

 

 

TOPICS

  • Microservices
  • CI/CD
  • Microservice Container Management
  • Docker
  • Message-based microservices architecture
  • Couchbase schema on read for microservices

After completing this course, the student should be able to:

  • Confidently use the stack outlined in the course.
  • Understand the various key components.
  • Apply the knowledge to migrate applications to microservice architected solutions on Docker, Kubernetes, and Jenkins with OpenShift
  • Understand the various components in a containerized microservice environment for CI/CD

 

What are microservices?

The central idea behind microservices is that some types of applications become easier to build and maintain when they are broken down into smaller, composable pieces that work together.

Each component is continuously developed and separately maintained, and the application is then simply the sum of its constituent components. This is in contrast to a traditional, “monolithic” application which is all developed all in one piece.

Applications built as a set of modular components are easier to understand, easier to test, and most importantly easier to maintain over the life of the application. It enables organizations to achieve much higher agility and be able to vastly improve the time it takes to get working improvements to production. This approach has proven to be superior, especially for large enterprise applications that are developed by teams of geographically and culturally diverse developers.

There are other benefits:

  • Developer independence: Small teams work in parallel and can iterate faster than large teams.
  • Isolation and resilience: If a component dies, you spin up another while and the rest of the application continues to function.
  • Scalability: Smaller components take up fewer resources and can be scaled to meet increasing demand of that component only.
  • Lifecycle automation: Individual components are easier to fit into continuous delivery pipelines and complex deployment scenarios not possible with monoliths.
  • Relationship to the business: Microservice architectures are split along business domain boundaries, increasing independence and understanding across the organization.
