Kubernetes vs Docker is now popular among the IT domain, specifically in cloud computing. But do you know what it is really? It is important to learn about it before getting into cloud computing as a professional or for your business.

The term Kubernetes vs Docker itself is deceitful as it gives off a sense of rivalry between two competitors. Rather, one of them was adapted from the other to work symbiotically for the proper management of your application.
We cannot go further on Kubernetes and Docker without shedding some light upon containers.
Containers are software that allows applications to work reliably when moved from one computing environment to another. This allows the software programs to be deployed consistently and infallibly during displacement from the development stage to production. The shift could be anything from the host environment to the test environment, from desktop to a cloud service, etc.
Container orchestration is the management of individual containers that aids in automated deployment, scaling, and networking of the same to run in multiple environments.
Docker is the most popular container engine, open-sourced for developers and administrators to manage, shift, and run applications. It allows the developed application to run the same in any environment without any distortion even when decoupled.
Docker provided a standard way for packaging and shipping. But there came a need for the coordination, health checking, and authentication of the application. The auto-scaling and replication of the components were required. Also, a solution was demanded when there is an error and a way to restart it. This is when orchestrating containers came to rescue, and Kubernetes is an alternative for it.
Features of Docker:
- Quick application deployment.
- Consistency in every stage of the environment.
- Constant development and integration
- Effective resource utilization
While Docker is a containerization technology, Kubernetes or K8s is open-source container orchestration. It was initially developed by Google but now open-sourced for further developments. Kubernetes is the ideal container system to work applications in the cloud. Kubernetes can run and schedule applications. Basically, Kubernetes starts the work where Docker stops.
However, Docker.Inc has developed its own container orchestration platform Docker SWARM, equivalent to Kubernetes. Though, the establishment of Kubernetes has allowed it to be widely used rather than the Docker SWARM.
Features of Kubernetes:
- Auto-scaling of applications
- Instant updates
- Monitoring and health checking
- Authentication of software
- Provides completely container-centric development environment
In toto, Docker and Kubernetes have been a godsend to developers for the integrated working of systems.
