Have you heard the name Kubernetes, it is another open source in the market by Google and works one Containers, like Docker on Cloud.
Kubernetes v1.0 was released on July 21, 2015 by Cloud Native Computing Foundation (CNCF).
Future is changing on application and cloud so you should be knowing what is going on. Kubernetes is supported by almost all the cloud computing’s,
Microsoft for its Azure Kubernetes Service (AKS), Amazon for its Elastic Container Service for Kubernetes (EKS), Google for its Google Kubernetes Engine (GKE), IBM for its IBM Cloud Kubernetes Service (IKS)
My understanding is the Kubernetes is more of a load balancer, distributed system for containers for heavy loaded application.
Keep yourself updated.
