Docker Certified Associate Certification Training Course - Differentiate Docker and Virtualization

The video tutorial compares virtualization and Docker containers. It explains that virtualization requires a hypervisor and a guest operating system, leading to resource wastage. In contrast, Docker containers share the host operating system, making them lightweight and efficient. The tutorial highlights that containers are better for short-term tasks and quick scaling, while virtual machines are suited for long-term use and resource-intensive functions. Containers are easier to move across environments due to their smaller size and shared OS.

Explain why containers are considered lightweight compared to virtual machines.

In what scenarios would you prefer to use a virtual machine over a container?
