Kubernetes is an open-source container orchestration system designed to automate the deployment, scaling, and management of containerized applications. It was developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF). Kubernetes provides a platform-agnostic way to manage containerized applications, making it easy to deploy and run applications in any environment.

One of the key features of Kubernetes is its ability to manage containerized applications at scale. With Kubernetes, it's possible to deploy and manage applications across multiple hosts and clusters, automatically scaling up or down based on demand. This makes it easier to handle large-scale applications with complex deployment requirements.

Another important feature of Kubernetes is its support for declarative configuration and automation. Kubernetes uses YAML files to define the desired state of an application, and then automatically works to ensure that the current state matches the desired state. This makes it easier to manage and update applications over time, while also reducing the risk of errors and downtime.
