- So what is kubernetes, exactly? It is an open-source system for automating deployment, scaling, and management of containerized applications. - With its great API and features like Self-Healing, AutoScaling, Rollout Control, Resource Management, Built-in Service discovery and more; Kubernetes has gained a lot of popularity with more and more companies adopting it. For example the likes of ebay, Philips, SAP, Pokemon Go and others are stated in their official website as Kubernetes users. Also, Kubernetes runs anywhere. It can be deployed on virtual machines or bare metal servers running in the public cloud, or on premises. Because of this, Kubernetes on its own is a great tool for inter-operability. So let’s have a look at the kubernetes architecture.
