Top 6 Benefits of Using Docker for Development and OperationsPosted by Have Nielsen on May 20th, 2021 
What is Docker
Running applications in containers instead of virtual machines is increasing momentum in the IT world. Technology is supposed to be one of the fastest-growing in the current history of the software industry. At its heart lies Docker, a platform that enables users to pack, distribute, and manage applications within containers easily. In other words, It is an open-source project that automates the deployment of applications inside software containers.
Docker expert makes it easier to create, deploy, and run applications by using containers. Containers enable a developer to package up an application with all of the parts it requires, such as libraries and other provinces, and ship it all out as one package. The developer can be confirmed that the application will work on any other Linux machine despite any customized settings that the machine might have that could differ from the device used for writing and testing the code.
1. Return on Investment and Cost Savings
The first benefit of using docker is ROI. The biggest operator of most management decisions when choosing a new product is the return on investment. The more a solution can drive down expenses while increasing profits, the better a solution is, particularly for large, established companies, which require creating steady revenue over the long term.
In this sense, Docker can help promote this type of savings by dramatically decreasing infrastructure resources. The nature of Docker is that some resources are needed to run the same application. Because of the decreased infrastructure requirements Docker has, organizations can save on everything from server costs to the employees required to maintain them. Docker enables engineering teams to be smaller and more efficient.
2. CI Efficiency
Docker expert allows you to create a container image and use that same image over every deployment process step. A considerable benefit of this is the capability to separate non-dependent actions and run them in parallel. It can speed up the length of time it takes from build to production.
3. Compatibility and Maintainability
Drop the “it works on my machine” problem once and for all. One of the advantages that the whole team will appreciate is parity. In terms of Docker, Parity means that your images run the same no matter whose laptop or which server they are working on. For your developers, this means less time-consuming setting up environments, debugging environment-specific problems, and an easy-to-set-up and more portable codebase. Parity also means your production infrastructure will be more accessible and more reliable to maintain.
4. Simplicity and Faster Configurations
One of the essential benefits of Docker is the way it clarifies matters. Users can take their configuration, set it into code, and deploy it without any issues. As Docker can be used in various environments, the infrastructure requirements are no longer associated with the application's environment.
5. Rapid Deployment
Docker expert commands to decrease deployment to seconds. This is because it creates a container for every process and does not boot an OS. Data can be made and destroyed without concern that the cost to bring it up again would be greater than what is affordable.
6. Security
The last of these advantages of using docker is security. Docker ensures that running on containers is wholly separated and isolated from each other, granting you complete control over management and traffic flow from a security point of view. No Docker container can look into processes operating inside another container. Each container receives its own set of resources from an architectural perspective ranging from processing to network stacks.
