1. Built on microservices / distributed applications, containers provide infrastructure-as-code, libraries, configurations in a single package code.
With containers, you can easily scale up or scale down because of the independent nature of all the components. It provides process isolation allowing you to run and scale different components side-by-side regardless of the programming language or libraries running in each container.

2. Avoid vendor lock-in and improve profitability with multi-cloud platforms.
Containers enable you deploy in seconds, with all code, dependency and configurations in a single package. The Docker file can be deployed on virtually any system across AWS, VMware, Cisco etc.
3. Enable continuous integration & deployment as Docker provides a system for image versioning.
You can setup your build process to pull the code from a repository, build it, package it into a Docker image, and push the newly created image into an image repository. You can avoid applications failing in production because the Docker daemon is the same across your development, staging, and production systems.
4. Containers ensure consistent environments from development to production.
Docker containers are configured to maintain all configurations and dependencies internally. As a result, you can use the same container from development to production making sure there are no discrepancies or manual intervention.
5. Docker containers ensure consistency across multiple development and release cycles, standardizing your environment.
Docker containers work just like GIT repositories, allowing us to commit changes to Docker images and version control them. If we perform a component upgrade that breaks our whole environment, it is very easy to roll back to a previous version of the Docker image.
6. Faster product development without compromising on security & authenticity.
No Docker container can look into processes running inside another container. From an architecture standpoint, each container gets its own set of resources ranging from processing to network stacks. Digitally signed Docker images ensure authenticity.
