Microservices – Developer

Course Overview:

The course is designed by App modernization Subject Matter Experts to help you understand concepts of Microservices, understand monotonic application , break the monolithic application into 3 microservices during the class hours . each microservice (MS) will be written in different language ( MS1 in .net core, MS2 in python, MS3 in Java spring boot) . expose the microservices with kong api and then connect the microservices using messaging bus .You will also learn to containerize your app and run on Kubernetes

Course Duration:

• 28 hours (4 Days)
