Description

*** Updated for latest CKA (2022) 1.24 version of Exam ***Kubernetes is one of the highest trending technology in Cloud Computing as of today. Kubernetes had the fastest growth in job searches, over 173% from a year before as reported recently by a survey conducted by Indeed.Learn, practice, and get certified on Kubernetes with hands-on labs right in your browser."I have compared this to other courses at Udemy and Linux Academy. All have the strengths and gaps, so far this is a winner!" -  Thomas Trauss, StudentLearning Kubernetes is essential for any DevOps professional. DevOps engineers are always in demand. Currently, the average Silicon Valley salary for a DevOps engineer is 20% higher than what a software engineer makes. DevOps engineers make an average of $140,000 to $200,000 annually. And One of the most in-demand skills is Kubernetes Administration.Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation.                                                                                                    Simplify Complex TechnologyKubernetes is at the cutting-edge of application deployment. To elevate your DevOps career, learn how to effectively deploy applications on Kubernetes.This course helps you gain the knowledge required to design and deploy cloud-native applications on a Kubernetes cluster.  A series of well-designed lectures with animation and illustrations help you understand complex concepts easily.                                                                                                      Practice! Practice! Practice!Lectures alone won’t help you clear the certification. The Kubernetes Certification is a practical hands-on exam. You need hands-on experience, you need to get fast and you need practice. That is what our integrated hands-on lab experience gives you.
