'Kubernetes' or 'K8s' automates deployment, scaling, and management of containerized applications. Originally designed by Google, it's now the standard for orchestrating containerized software.

Kubernetes organizes containers into logical units for better management and discovery. It efficiently manages resources for optimal operation of containers.

Features of Kubernetes include load balancing, automated rollouts, storage orchestration, and support for batch execution. It's compatible with a range of container tools, including Docker.

Kubernetes is essential in modern software development for its scalability, powerful features, and support for cloud-native applications.
