Docker

Docker is a platform that allows developers to package applications and their dependencies into portable containers. These containers are lightweight and contain everything needed for an application to run consistently, regardless of where it's deployed. This means that software can run smoothly on different environments, such as a developer's laptop, a server, or in the cloud. Docker simplifies the process of managing and scaling applications, making it easier for teams to collaborate, develop, and deploy software efficiently. Essentially, it helps ensure that "it works on my machine" also applies everywhere else.
