Why Learn Kubernetes?

Kubernetes is one of the most in-demand skills today because:

• Companies are moving to the cloud, and Kubernetes is the leading platform for container orchestration.
• It supports scaling, self-healing, and high availability.
• It’s key to understanding DevOps, container orchestration, and infrastructure automation.
• It helps you stand out in the job market—Kubernetes engineers are in high demand.
• Kubernetes works with all major cloud providers (AWS, GCP, Azure), so you're not tied to one platform.
