Impact Of Kubernetes In IT Market
Kubernetes and Docker are the two words you hear most in conversation about DevOps today. Docker is a tool that allows you to contain and run applications, and Kubernetes provides a platform to orchestrate or manage these containers, since managing the thousands of containers manually with Docker CLI is a very costly task.
Kubernetes is an open source software to implement and manage those containers on a large scale. It enables any number of servers of many types at the same type at the same time, separated by distance, to share workloads for a common tenant.
Some Of Its Features Include:
· The ability to automatically place containers according to your resource requirements without affecting availability.
· Service discovery and load balancing no need to use eternal mechanism for service discovery as Kubernetes assigns containers and their own IP address and a unique DNS names for a set containers and can balance the load on them.
· Planning it is in change of decide in which node each container will run according to the resources it requires and other restrictions. It mixes critical and best-effort workloads to enhance resource utilization and savings.
· Enable storage orchestration automatically set up the storage system as a public cloud provide. Or an on-premise networked storage system such as NFS, iSCL, Gluster, Ceph, Cinder and others.
· Batch execution in addition to services, Kubernetes can manage batch and IC workloads, replacing failed containers.
· Configuration and secret management sensitive information such as password or ssh keys stored in Kubernetes hidden in “secrets”. Both the application’s configuration and secrets are deployed and updated without having to rebuild the image or expose sensitive information.
· Self-repair failed containers, replace and re-program them nodes die. Also remove unresponsive containers and do not publish them until they are ready.
