Certified Kubernetes Administrator Course Description
Certified Kubernetes Administrator (CKA) 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.
Kubernetes foundation course or equivalent professional experience.

Course Delivery Method
This course is delivered through:
- Self-paced Training
This course allows you to test new skills and apply knowledge to your working environment through a variety of practical exercises.
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.
