→ What is Kubernetes ?

Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.

Planet Scale

Designed on the same principles that allows Google to run billions of containers a week, Kubernetes can scale without increasing your ops team.

Never Outgrow

Whether testing locally or running a global enterprise, Kubernetes flexibility grows with you to deliver your applications consistently and easily no matter how complex your need is.

Run K8s Anywhere

Kubernetes is open source giving you the freedom to take advantage of on-premises, hybrid, or public cloud infrastructure, letting you effortlessly move workloads to where it matters to you.

→ Why Kubernetes ?

  1. Kubernetes is a powerful container management tool that automates the deployment and management of containers. Kubernetes (k8’s) is the next big wave in cloud computing and it’s easy to see why as businesses migrate their infrastructure and architecture to reflect a cloud-native, data-driven era.
  2. Container Orchestration.
  3. Great for multi Cloud Adoption.
  4. Deploy and update application at scale for faster and time-to-market.
  5. Better Management of application.

→ When to use Kubernetes ?

If your application uses a microservice architecture
If you have transitioned or are looking to transition to a microservice architecture then Kubernetes will suit you well because it’s likely you’re already using software like Docker to containerize your application.

If you’re suffering from slow development and deployment
If you’re unable to meet customer demands due to slow development time, then Kubernetes might help. Rather than a team of developers spending their time wrapping their heads around the development and deployment lifecycle, Kubernetes (along with Docker) can effectively manage it for you so the team can spend their time on more meaningful work that gets products out the door.

→ Pokemon Go’s Kubernetes story…

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. 500+ million downloads and 20+ million daily active users.

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

The challenge

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

The solution

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 got them more time to concentrate on building the game’s application logic and new features rather than worrying about the scaling part.

→ Conclusion

Around the world, many CIO’s and technologists have chosen to use Kubernetes, and it is expected to evolve much more in the years to come.

Containers are becoming more and more popular in the software world and Kubernetes has become the industry standard for deploying containers in production. We will expect a high growth rate of Kubernetes this year too.
