What is a key benefit of using Docker containers?

The key benefit of using Docker containers is that they allow for quick deployment of applications. This speed stems from the lightweight nature of containers compared to traditional virtual machines. Containers package the application and its dependencies into a single unit, which can be rapidly deployed and started on any system that has the Docker platform installed. This capability significantly reduces the time needed to set up and configure environments, facilitating continuous integration and continuous deployment (CI/CD) practices.

With Docker, developers can create images that encapsulate their applications and dependencies, enabling consistent and reproducible deployments across different environments, whether in development, testing, or production. This results in improved operational efficiency, agility, and the capability to scale applications quickly as required.
