How Kubernetes is used in Industries and what all use cases are solved by Kubernetes?

>>What is Kubernetes

Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.

Kubernetes is a tool in the Container Tools category of a tech stack.

Kubernetes is an open source tool with 72.9K GitHub stars and 26.4K GitHub forks. Here’s a link to Kubernetes’s open source repository on GitHub

Features of Kubernetes:

• Interacts with several groups of containers: Kubernetes is able to manage more cluster at the same time
• Provides additional services: as well as the management of containers, Kubernetes offers security, networking and storage services
• Self-monitoring: Kubernetes checks constantly the health of nodes and containers
• Horizontal scaling: Kubernetes allows you scaling resources not only vertically but also horizontally, easily and quickly
• Storage orchestration: Kubernetes mounts and add storage system of your choice to run apps
• Automates rollouts and rollbacks: if after a change to your application something goes wrong, Kubernetes will rollback for you
• Container balancing: Kubernetes always knows where to place containers, by calculating the “best location” for them
• Run everywhere: Kubernetes is an open source tool and gives you the freedom to take advantage of on-premises, hybrid, or public cloud infrastructure, letting you move workloads to anywhere you wants of Kubernetes

Use Case of kubernets in Pokemon Go

How was Pokemon Go able to scale so efficiently became so successful? The answer is Kubernetes. Pokemon Go was developed and published by Niantic Inc., and grew to 500+ million downloads and 20+ million daily active users.

Pokemon Go engineers never thought their user base would increase exponentially to surpass expectations within a short time. They were not ready for it, and the servers couldn’t handle this much traffic.

Pokemon Go also faced a severe challenge when it came to vertical and horizontal scaling because of the real-time activity by millions of users worldwide. Niantic was not prepared for this.

The solution was in the magic of containers. The application logic for the game ran on Google Container Engine (GKE) powered by the open source Kubernetes project. Niantic chose GKE for its ability to orchestrate their container cluster at planetary-scale, freeing its team to focus on deploying live changes for their players. In this way, Niantic used Google Cloud to turn Pokémon GO into a service for millions of players, continuously adapting and improving. This gave them more time to concentrate on building the game’s application logic and new features rather than worrying about the scaling part.
