EngineWhat is Docker?

It is an open platform which is ideal for shipping, developing and running different applications. It is designed to deliver applications in a faster manner. Docker will help you separate applications from infrastructure. Infrastructure can be treated like managed applications. Docker is designed to help in coding as well. It can help you with testing, shipping and deploying codes in a faster manner. The cycle between writing and running codes is reduced as a result of this platform being deployed.

How it works?

Docker performs these functions due to its ability to containerize kernels. There are tooling features and workflows that help you to manage as well as deploy applications easily. Docker in its essence helps to run applications securely and in an isolated manner. Security and isolation are beneficial aspects of the platform which allows you to run several containers at the same time on the host platform. The containers are lightweight applications and do not need a hypervisor to operate.

How it can help?

Docker is designed to help you get more out of your applications. There are several tools offered, which work in different ways:

  • You will be able to get your applications on Docker containers easily.
  • The containers can be distributed to different teams for testing and development.
  • Applications can be easily deployed for production through this platform.
  • You can use this platform even when applications are on the Cloud or in a data center.

Developing applications

Docker will help in the lifecycle of development of any application code. Developers will be able to develop in local containers which will segregate different applications and codes. You can integrate different containers in order to create a continuous workflow and deploy them accordingly. Developers can write codes in a local environment and share the stack of developed codes with their colleagues with the help of Docker. This can be done simply by pushing the code and stack into a test environment. Any tests required can be executed in this manner.

Deployment and scaling

This is done in an easier manner with Docker’s platform. Portable workloads are easy to deploy on this platform. Containers of this platform can run on a local host platform of a developer as well as on virtual machines in a data center as well as in a Cloud.

Other benefits

There are several other benefits and advantages that the platform provides. It has a lightweight and portable nature due to which workloads can be managed easily. Docker helps to scale up applications as well as services. The speed at which scaling can be done; it allows the same to be done in real time. It can be a cost effective solution as compared to using hypervisor based machines like Photon OS that are not as lightweight as Docker.

Points to remember

Docker is an open source application and it can be downloaded from authorized sites. There are two main components of the application which are the Docker Hub, which is a software service platform while the Docker Engine works as an open source platform for containerization.
