Kubernetes is a platform for managing, and hosting containerized workloads and services. Kubernetes was first introduced in 2014 by Google and has since become the de facto standard for large scale container orchestration, powering anything from small startups to conglomerates like Google itself.
Kubernetes has rose to prominence because of its ability to deploy, scale and manage complex application across multiple containers and hosts. Since 2014 applications have grown considerably more complex. With that growth, new service paradigms such as the micro service architecture has gained in popularity.
Kubernetes offers the following main features:
- Automated deployment and scaling: Easily scale your application up or down based on demand.
- Self-healing capabilities: Automatically restarts failed containers and replaces or reschedules containers when nodes die.
- Service discovery and load balancing: Kubernetes can expose a container using the DNS name or its own IP address. If traffic to a container is high, Kubernetes is able to load balance and distribute the network traffic.
- Storage orchestration: Automatically mount the storage system of your choice, whether from local storage, public cloud providers, or network storage systems.
- Secret and configuration management: Deploy and update secrets and application configuration without rebuilding your image and without exposing secrets in your stack configuration.
