Course Reviews


The duration of this course is five days (forty hours)

The cost of this course is $3600 (plus all applicable taxes).

Microservices are an approach/architecture to software writing (coding). With the help of Microservices, systems are broken down into their tiniest elements making them independent of each other.Instead of a conventional monolith approach to software, where everything is assembled into one piece, microservices are all portioned and work together to complete the exact same tasks.Each one of these Individual components/elements or processes is a micro-service.

Using a microservice approach to application creation will increase durability and speed up the time to market.

After taking this course, developers can more quickly build, test, and deploy their applications, improving application time to market
