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

What is Kubernetes?

Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

The name Kubernetes originates from Greek, meaning helmsman or pilot. Google open-sourced the Kubernetes project in 2014. Kubernetes combines over 15 years of Google’s experience running production workloads at scale with best-of-breed ideas and practices from the community.

Kubernetes: The Container Orchestration Tool

Kubernetes allows you to manage hundreds of containers and clusters of hosts on which containers are executed. When you deploy your containerized applications to a group of computers, Kubernetes automates their distribution and scheduling, working as an orchestration platform to simplify the work of technical teams.

Particularly, in instances when you need to manage applications with hundreds of containers spread across multiple hosts, a container orchestration tool like Kubernetes manages the workloads in a compute cluster, connecting to the outside world for scheduling, load balancing, and distribution.

The Kubernetes DevOps Tool

The container orchestration capability of Kubernetes closes the gap between IT operations and development, making a great collaborative DevOps environment for sharing software and their dependencies seamlessly between different environments.

It facilitates the software lifecycle and the enabler teams in the build-test-deploy timeline:

• Developer environment, by helping to run the software in any setting
• QA/Testing process, through coordinated pipelines between test and production
• Sys-admin, by running anything once configured
• Operations, by offering a comprehensive solution for building, shipping, and scaling software

Kubernetes has emerged as a good actor in DevOps as it focuses on features and bugs rather than time-intensive tasks to enable better software to be shipped with a smooth DevOps workflow.

Why Kubernetes?

Imagine a situation where you have been using a container tool 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 die? This is where Kubernetes comes in.

Kubernetes Use Cases:

1. Reddit’s Kubernetes Story:

Reddit is one of the 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 far until they saw some huge drawbacks and failures happening while doing the things the old way. They moved to Kubernetes.

2.The New York Times’s Journey to Kubernetes:

Today the majority of the NYT’s customer-facing applications are running on Kubernetes. What an amazing story. The biggest impact has been an increase in the speed of deployment and productivity. Legacy deployments that took up to 45 minutes are now pushed in just a few. It’s also given developers more freedom and fewer bottlenecks. The New York Times has gone from a ticket-based system for requesting resources and weekly deploy schedules to allowing developers to push updates independently.

3.Airbnb’s Kubernetes Story:

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 1,000 or so engineers so they could add new services. Airbnb adopted Kubernetes to support over 1,000 engineers concurrently configuring and deploying over 250 critical services to Kubernetes (at a frequency of about 500 deploys per day on average). I want you to see this excellent presentation from Melanie Cebula, the infrastructure engineer at Airbnb.

4.Pinterest’s Kubernetes Story:

With over 250 million monthly active users and serving over 10 billion recommendations every single day, the engineers at Pinterest knew these numbers are going to grow day by day, and they began to realize the pain of scalability and performance issues.

Their initial strategy was to move their workload from EC2 instances to Docker containers; they first moved their services to Docker to free up engineering time spent on Puppet and to have an immutable infrastructure.

The next strategy was to move to Kubernetes. Now they can take ideas from ideation to production in a matter of minutes, whereas earlier they used to take hours or even days. They have cut down so much overhead cost by utilizing Kubernetes and have removed a lot of manual work without making engineers worry about the underlying infrastructure.

So these were some of the used cases of kubernates , like this there are may other examples as well.
