Kubernetes is an open-source container management/orchestration tool. Kubernetes container management responsibilities include container deployment, scaling & descaling of containers & container load balancing. An important point to note here is that Kubernetes is not a containerization platform. It is a multi-container management solution.
Now, going by the definition, you might feel Kubernetes is very ordinary and unimportant. But trust me, this world needs Kubernetes for managing containers, as much as it needs Docker for creating them.
With the advent of microservice architecture, users to individually scale key functions of an application and handle millions of customers.
On top of this, there are many other technologies such as Docker containers emerged in the enterprise, creating a consistent, portable, and easy way for users to quickly build these microservices.
While Docker continued to thrive, managing these microservices & containers became a paramount requirement. All you need is a robust orchestration platform which can manage those containers which host your entire application.
In this scenario Kubernetes comes to the rescue. Kubernetes is a robust orchestration platform which brings a number of features and which can be thought of as:
Kubernetes also provides a container-centric management environment. It orchestrates computing, networking, and storage infrastructure on behalf of user workloads. This provides much of the simplicity of Platform as a Service (PaaS) with the flexibility of Infrastructure as a Service (IaaS), and enables portability across infrastructure providers.
