It is an abbreviation of development and operations. It is a software engineering practice that aims to combine software development (Dev) and software operations (Ops) in an organization to improve the relationship between two business units.
The previous article on Docker gives all the details about Docker software and its architecture. In this article, we will learn about DevOps and Docker with DevOps.
Toptal explained the Docker DevOps concept with a transportation of goods we generally deploy. The picture depicts the improved transportation we imply for transporting the good from ancient times.

We use Ship containers as they can carry heavy loads cheaply and more secure making the transportation worry free about their goods and focus on getting them to transfer from A to B.
Now, let’s consider a software process. The time taken by software company from requirement analysis whiteboard diagram to finally a paying customer feature to the end user is called as “ lead time” just like transforming the good from A to B. All we want is this transformation to happen in a shortened time. That means the lead time has to decrease. One can achieve this short lead time by following three main principles. They are:
We can increase the Velocity by accelerating the process of flow of each component that is in pipeline. The developer, integration, and deployment flows are to increase in order to increase the velocity of each process.
Another method to increase velocity is the use of Union FileSystems and Copy on Write (COW) method. They are used to baseline and rebase between the network layers to increase the Velocity of a process.
Docker images are binary. This feature enables the developer to experience a non-codable deployment mechanism thus minimizing the variations. If a developer tests a set of Docker images on his laptop, it would be the same during the integration testing and the production deployment.
When services are bounded by their business context and then isolated as Docker containers they become visual. The increased visibility can help an organization discover ownership faster.
