To know what is docker in cloud computing, first, we need to understand what containers are in the cloud environment. A container is an executable part of the software that is embedded with application code and libraries and dependencies to run anywhere, be it on desktop or cloud. A container in cloud computing is used to build blocks, which help in producing operational efficiency, developer productivity, and environmental consistency. Containers are small, fast, and portable. Because of this, the user is assured of reliability, consistency, and quickness regardless.
Docker in cloud computing is a tool that is used to automate the deployment of applications in an environment designed to manage containers. It is a container management service. These containers help applications to work while they are being shifted from one platform to another. Docker’s technology is distinctive because it focuses on the requirements of developers and systems. This modern technology enables enterprises to create and run any product from any geographic location.
There are several problems associated with cloud environments and tries to solve those issues by creating a systematic way to distribute and augment the application. It helps to separate the applications from other containers resulting in a smooth flow. As its job, it is possible to manage our infrastructure, in the same ways we use to manage our applications, with the help of Docker.
A docker container image is structured in terms oflayers.’

Listed below are some of the benefits of Docker container:
Even though there are a lot of benefits associated with docker, it has some limitations as well, which are as follows:
Enterprises can adopt this modern strategy of working to grow their business and hence, achieve heights of success. The first reason why docker is good is due to the return on investment. Docker can help in reducing infrastructure resources. The nature of Docker is that it requires fewer resources that are necessary to run the same application.
Security is a primary concern for all organizations, and Docker specifically takes care in this regard so that security is not breached.
One of the biggest advantages of a Docker-based framework is standardization. Standardizing service infrastructure allows every team member to work in a parity environment. This helps engineers to analyze and fix bugs within the application efficiently. Docker delivers agility, resiliency, portability, security, and cost savings for all applications.
Docker in cloud computing security has undoubtedly taken a revolutionary step towards the management of deployment platforms. A container is a lightweight virtual machine that provides address space, network, and file isolation. Big corporations like AT&T, Verizon, Visa, Metlife, to name a few, are all using the services of docker. This itself speaks for their acceptability. In this modern age, time is of the essence, and docker, with its virtualization framework, streamlines the workflow for organizations.
