Course Description

Kubernetes Certified Administrator (KCA) is designed for individuals  experienced with designing, deploying and managing a Kubernetes Cluster either on-premise or in the cloud.  As a follow-up course to  Kubernertes Foundations course, it builds on concepts introduced in  that course. This course covers how to build complex Kubernetes cluster, scheduling, networking, storage, troubleshooting and Core concepts required to pass the CNCF Kuberntes Certified Administrator.

Course Outline

This course will follow the outline presented by Cloud Native Computing Foundation here.
Cloud Native Computing Foundation uses an open source software stack to deploy applications as microservices, packaging each part into its own container, and dynamically orchestrating those containers to optimize resource utilization. Kubernestes is a core part of the software hosted by CNCF. CNCF is part of The Linux Foundation, a nonprofit organization.
