What are the Benefits of Using Docker Containers & When Should They Be Used?

Too Long; Didn't Read

The biggest benefit of Docker is its ability to isolate the development and production systems for your applications. Each application container can be deployed on the same Docker host, which means you can use the same environment to test and run your application while it's in production.  Docker containers are more portable, faster, and less resource-intensive than virtual machines. They're also simpler to set up and manage. Docker containers allow you to run isolated applications in the same way that you would on any other computing platform. These isolated applications can be scaled up or down individually while they continue to run, making it easier to manage their performance and resources.
