Use Of Kubernetes In Industries?

What is Kubernetes?

According to official Kubernetes documentation,
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
In simple words- Kubernetes, or k8s, is an open source platform that automates Linux container operations, In other words, you can cluster together groups of hosts running Linux containers, and Kubernetes helps you easily and efficiently manage those clusters

History of Kubernetes?

According to wikipedia: Kubernetes (commonly stylized as k8s) is an open-source container-orchestration system for automating computer application deployment, scaling, and management.

It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”. It works with a range of container tools and runs containers in a cluster, often with images built using Docker. Kubernetes originally interfaced with the Docker runtime through a “Dockershim”; however, the Shim has since been deprecated in favour of directly interfacing with containerised or another CRI-compliant runtime.

Many cloud services offer a Kubernetes-based platform or infrastructure as a service (PaaS or IaaS) on which Kubernetes can be deployed as a platform-providing service.

Kubernetes (κυβερνήτης, Greek for “helmsman” or “pilot” or “governor”, and the etymological root of cybernetics) was founded by Joe Beda, Brendan Burns, and Craig McLuckie, who were quickly joined by other Google engineers including Brian Grant and Tim Hockin, and was first announced by Google in mid-2014. Its development and design are heavily influenced by Google’s Borg system, and many of the top contributors to the project previously worked on Borg. The original codename for Kubernetes within Google was Project 7, a reference to the Star Trek ex-Borg character Seven of Nine. The seven spokes on the wheel of the Kubernetes logo are a reference to that codename. The original Borg project was written entirely in C++,[11] but the rewritten Kubernetes system is implemented in Go.

Kubernetes v1.0 was released on July 21, 2015. Along with the Kubernetes v1.0 release, Google partnered with the Linux Foundation to form the Cloud Native Computing Foundation (CNCF) and offered Kubernetes as a seed technology. In February 2016 Helm package manager for Kubernetes was released. On March 6, 2018, Kubernetes Project reached ninth place in commits at GitHub, and second place in authors and issues, after the Linux kernel. Up to v1.18, Kubernetes followed an N-2 support policy (meaning that the 3 most recent minor versions receive security and bug fixes) From v1.19 onwards, Kubernetes will follow an N-3 support policy.

Why do we need kubernetes and what are the uses?

Containers are a good way to bundle and run your applications. In a production environment, you need to manage the containers that run the applications and ensure that there is no downtime. For example, if a container goes down, another container needs to start. Wouldn’t it be easier if this behavior was handled by a system?

That’s how Kubernetes comes to the rescue! Kubernetes provides you with a framework to run distributed systems resiliently. It takes care of scaling and failover for your application, provides deployment patterns, and more. For example, Kubernetes can easily manage a canary deployment for your system.

1. Service discovery and load-balancing
2. Storage orchestration
3. Automated rolls outs and rolls back
4. Automatic pin backing
5. self-healing
6. Secret and configuration management

Companies using Kubernetes?

Big Companies such as Tinder, Reddit, New York Times, Airbnb or Pinterest have integrated this technology into their services.

so what specifically can Kubernetes do for me?

Here are five fundamental business capabilities that Kubernetes can drive in the enterprise–be it large or small. And to add teeth to these use cases, we have identified some real world examples to validate the value that enterprises are getting from their Kubernetes deployments

1. Faster time to market
2. IT cost optimization
3. Improved scalability and availability
4. Multi-cloud (and hybrid cloud) flexibility
5. Effective migration to the cloud

Few Use- cases of Kubernetes?
