Why Kubernetes? Why companies are adopting Kubernetes (K8s)
I mean why not kubernetes? Imagine a situation where you have been using Docker for a little while, and have deployed on a few different servers. Your application starts getting massive traffic, and you need to scale up fast, how will you go from 3 servers to 40 servers that you may require? And how will you decide which container should go where? How would you monitor all these containers and make sure they are restarted if they exit?
Yes, this is why we need kubernetes. Let us take a look at how some of the most successful companies of our time are successfully using Kubernetes.
Tinder
Due to high traffic volume, Tinder’s engineering team faced challenges of scale and stability. What did they do?
Yes, the answer is Kubernetes.
Tinder’s engineering team solved interesting challenges to migrate 200 services and run a Kubernetes cluster at scale totaling 1,000 nodes, 15,000 pods, and 48,000 running containers.
Was that easy? No ways. However, they had to do it for the smooth business operations going further.
Reddit is one of the top busiest sites in the world. Kubernetes forms the core of Reddit’s internal Infrastructure.
From many years, the Reddit infrastructure team followed traditional ways of provisioning and configuring. However, this didn’t go long until they saw some huge drawbacks and failures happening while doing the things the old way. They moved to ‘Kubernetes.’
Airbnb
Airbnb’s transition from a monolithic to a microservices architecture is pretty amazing. They needed to scale continuous delivery horizontally, and the goal was to make continuous delivery available to the company’s 1000 or so engineers so they could add new services. Airbnb adopted to support over 1000 engineers concurrently configuring and deploying over 250 critical services to Kubernetes (at a frequency of about 500 deploys per day on average).
