Kubernetes is an open-source container orchestration platform for automating the deployment, scaling, and management of containerized applications. With Kubernetes, developers can deploy applications across clusters of machines, ensuring high availability, scalability, and resilience. Developers can learn about Kubernetes' architecture, core concepts, and deployment strategies, and gain hands-on experience with managing containerized workloads using Kubernetes.
