Kubernetes Introduction
Why Kubernetes
A lot of developers have moved or are moving from a traditional world to a container based ecosystem. This allows developers to package their application code, dependencies and required libraries in a simple container and use it anywhere wherever there is a container runtime available.
An example of a container runtime is Docker
At a minimum, Kubernetes can schedule and run application containers on clusters of physical or virtual machines. However, Kubernetes also allows developers to ‘cut the cord’ to physical and virtual machines, moving from a host-centric infrastructure to a container-centric infrastructure.
This approach provides the full advantages and benefits inherent to containers. Kubernetes provides the infrastructure to build a truly container centric development environment. This is the primary reason developers love it.
What is Kubernetes
With Kubernetes, you are able to quickly and efficiently respond to customer demand
- Deploy your applications quickly and predictably
- Scale your applications on the fly
- Roll out new features seamlessly
- Limit hardware usage to required resources only
- Our goal is to foster an ecosystem of components and tools that relieve the burden of running applications in public and private clouds
According to Brian Grant Kubernetes is an open-source platform designed to automate deploying, scaling, and operating application containers.
Kubernetes is
- Portable: public, private, hybrid, multi-cloud
- Extensible: modular, pluggable, hookable, composable
- Self-healing: auto-placement, auto-restart, auto-replication, auto-scaling
Google started the Kubernetes project in 2014. Kubernetes builds upon a decade and a half of experience that Google has with running production workloads at scale, combined with best-of-breed ideas and practices from the community.
