Containerizing Software Applications (DO276)

Through hands-on labs, students will take a monolithic application and break it down into its distinct services thereby illustrating how containers are an excellent vehicle for microservices architecture deployment.

Intended Audience
This course is intended for developers, architects, and system administrators who wish to learn how to deploy containerized applications using Red Hat® Enterprise Linux® Atomic Host software and what changes might make them well-behaved applications in a container environment.
