Kubernetes and Docker: Either or Both?

Kubernetes and Docker:

These two remarkably popular platforms adopted for managing containers and much more may seem to be competing technologies. Kubernetes and Docker are essential if you are willing to build a modern cloud infrastructure and run it.
Kubernetes and Docker are popular as ‘managing containers’, and it may seem that they are in each other’s competition right now. Nevertheless, by the end of this article, you will find out that they, in many ways are actually complementary. These systems provide many techniques to build and manage virtual containers. But their systems differ significantly. Furthermore, they can even work together.

What is Kubernetes:  

Kubernetes is an open-source container management system or a container-orchestration designed by Google. The CNCF (Cloud Native Computing Foundation) manages it now. It aims at providing, automating deploy, scaling and managing operations for developers interested in Linux containers.

What is docker:

Docker is an open-source virtualisation technology known as containerization platform for software containers. Docker introduces a simple way to construct, deploy and run containers on Linux machines. They now can run on Windows too. They build a hierarchy of images to compose and create brand new images. Docker has its own clustering solution for its containers known a the Swarm. It uses its own API. Docker’s Swarm provides a way to manage and maintain a large number of containers dispersed across several server clusters. To deploy containers in a cluster, its filtering and scheduling system enables the selection of optimal nodes.
Docker is right now, the most popular container platform. Whereas, Kubernetes is the market leader and the standardised means of orchestrating containers and deploying distributed applications.

It has cloud bursting capabilities, benefits of both public and private environments. Why use hybrid cloud over the public and private cloud? Hybrid cloud computing empowers an enterprise to establish an on-premises private cloud to host critical workloads and use a third-party public cloud provider to host less critical resources, such as development and test workloads. It is also essential for highly changeable workloads. Another valuable hybrid cloud use case is big data processing. For instance, a company can use hybrid cloud storage to hold on to its b...
