Microservices Bootcamp - 3 Day

 

For IT professionals, developers, software engineers, and DevOps practitioners – microservices training provides the technical practices and tooling fundamentals necessary to begin realizing the benefits of microservices as a foundation for IT architecture, software engineering, and service/release delivery.

 

The workshop includes 16 hands-on exercises which give you real-world practice on the engineering tools and skills a team needs in order to realistically implement your own flavor of Microservices architecture patterns so you can address the team needs of your own organization.

Whether you want to create new services, decouple a few services from your overall architecture, or refactor an entire monolithic architecture into a microservices design pattern, this course quickly teaches you the practical toolset and skills to get up and running with microservices in your own systems. Loosely coupled components and services allow teams to deploy more freely and independently, with less risk to the architecture. At the end of this course, you will be able to:

  • Adopt, plan or improve your transition to Microservices

  • Map technical practices to the business strategy behind Microservices

  • Navigate different tools for enabling microservices and how to use them

  • Communicate with stakeholders, management, and teams regarding needs and expectations around Microservices

  • Get hands-on practice with Docker, Kubernetes, Jenkins, and JFrog tools for core micro-services architecture

  • Get hands-on practice with the toolchain in our real-world application labs

  • Build more mature DevOps practices through micro-services adoption

  • Understand how to refactor monolithic systems into more modular, component- based systems

  • Apply micro-services use cases to continuous integration, delivery, and testing

  • Enable more automated testing and self-service QA capability
