What is Kubernetes exactly?

Everyone working in cloud tech talks about it, but many people are in need of a basic 101. So: what is Kubernetes?

Kubernetes is a portable, open-source container structure that allows users to automate enterprises’ container procedures. Teams can automate application deployment, scaling, processes, and management. This makes it much easier for businesses to manage their containers. Kubernetes was originally designed by Google; today, it is overseen by the Cloud Native Computing Foundation. 

Why is Kubernetes so important?

Because it has the power to knock out a multitude of manual operations used to scale and deploy applications with containers, freeing up time for teams to focus on other aspects of business. Kubernetes gives users the power to conveniently and precisely regulate and oversee clusters of bundled hosts operating in containers. These clusters can reach varied hosts including public, private, and even hybrid clouds, safely. In short, if you want to efficiently manage containers, Kubernetes is essential. 

Key features of Kubernetes include: 

  • Additional servers are able to be both added and taken out. 
  • Regularly adjusts operating containers, through referencing alternative application metrics. 
  • A replication controller which monitors clusters to ensure they have an equivalent number of pods operating. 
  • In addition, the pod will remove extra pods, or add more based on how many are operating to ensure they are balanced. 
  • Oversees how both nodes and containers are running to prevent crashes. 
  • Able to repair the pods or containers to prevent breakdowns. 
  • Route traffic to the suitable containers. 

Consequently, Kubernetes is the optimal system for accommodating cloud-native applications that demand accelerated scaling. It is able to reduce cloud costs through providing clusters with constant resources. In addition, Kubernetes is automated. Therefore, the system eliminates the manual scaling and deploying aspect, resulting in more time for businesses to utilize.
