Docker and Kubernetes

  1. What is docker? 

Docker is a virtualisation tool/platform that allows developers to run different OS on the same machine. Docker virtualisation is done on the system level, which is known as docker containers. These containers are different from Hypervisors. Hypervisors are used to create virtual machines. 

Here below is an image in which you can see the difference between machine virtualisation and a docker container.  Docker containers run in an isolated environment above the host’s operating system. This helps the developer improve efficiency, security and less maintenance. If a user is operating on a Windows OS, the user can still have Linux images running in containers with the help of Hyper-V/WSL2.

  1. What is Kubernetes?  

"Kubernetes is a container management system developed on the Google platform. Kubernetes helps to manage containerised applications in various types of physical, virtual, and cloud environments. Google Kubernetes is a highly flexible container tool to consistently deliver complex applications running on clusters of hundreds to thousands of individual servers.” -guru99  

Kubernetes is a distributed system kernel based on the Linux kernel. It allows you to encapsulate the underlying hardware of the nodes (servers) and provides a standard interface for programs that use the shared resource pool. 

Containers: The modern internet user does not tolerate downtime. As a result, developers must perform maintenance and updates without disrupting their services. As a result, containers are separated environments. It contains everything required for the application to function. It makes editing and deploying programs simple for developers. Containerization has also become a popular way of packaging, deploying, and updating web applications.


  • Features of Kubernetes:
  1. Automated Scheduling 
  2. Self-Healing Capabilities 
  3. Automated rollouts & rollback
  4. Horizontal Scaling & Load Balancing
  5. Offers environment consistency for development, testing, and production 
  6. Infrastructure is loosely coupled to each component can act as a separate unit 
  7. Provides a higher density of resource utilization 
  8. Application-centric management 
  9. Auto-scalable infrastructure 
  10. You can create predictable infrastructure.
