Kubernetes is an open-source platform that is used for container orchestration in the cloud environment. It helps automate deployment, scaling and management of containerized applications. Kubernetes is designed to work with multiple cloud providers, including Google Cloud, Microsoft Azure, and Amazon Web Services (AWS).
In Kubernetes, the basic unit of deployment is a container, which is packaged within a larger “pod”. Kubernetes creates and manages these pods, which can contain a single container or multiple containers that can be deployed across multiple servers. Kubernetes also provides features like automatic scaling, self-healing, and rolling deployment updates.
Some of the key features of Kubernetes include:
- Auto-scaling: Kubernetes automatically scales up or down to accommodate changes in traffic or resource usage.
- Self-healing: Kubernetes detects and automatically replaces failed containers or pods.
- Load balancing: Kubernetes can distribute traffic evenly among multiple containers or pods.
- Storage orchestration: Kubernetes can manage the storage required by applications.
- Service discovery and routing: Kubernetes provides an internal DNS system that helps to discover and route network traffic to the containers.
Overall, Kubernetes helps to simplify the management and scaling of containerised applications while ensuring their availability, reliability, and security in production.
