DO720 Container Adoption Boot Camp for Developers
Course description
Supporting the adoption of container technology through the development of container-native applications
The Container Adoption Boot Camp for Developers (DO720) immerses you in intensive, hands-on development of container-native applications deployed on Red Hat's implementation of Kubernetes, Red Hat® OpenShift® Container Platform. As part of enrollment, you will receive one year of Red Hat Learning Subscription Standard, which gives you unlimited access to all of our courses online, plus up to five certification exams and two retakes.
This collection of courses is based on Red Hat OpenShift Container Platform 4.

Impact on the organization
This bootcamp is intended to provide container-novice developers with the foundational and advanced skills needed to develop, deploy, and troubleshoot microservices applications with the Red Hat OpenShift Container Platform. Red Hat OpenShift Container Platform enables rapid application development and deployment, as well as portability of an application across environments. The platform also offers simplified application scaling, administration, and maintenance of adapted or cloud-native applications.
Impact on the individual
