Microservices Architecture
Course number: CGIMAR40
Microservices Architecture is one of the methods for implementing a service-oriented architecture. The Microservices Architecture course helps you gain expertise in developing a Microservices Architecture-based solution. Apply Microservices principles to specific business requirements to build a scalable & performing solution. You will learn about various Microservices architectural styles, how to select the appropriate architecture design, and how Netflix has used Microservices to scale.
