Containers and virtual machines are used all across cloud infrastructure. Cloud providers utilizes virtualization to divvy up hardware resources so that they can maximize hardware utilization on their machines. Docker is used to develop, deploy, and ship applicaiations quickly with low overhead some isolation.

Virtual machines are super useful! They allow users to create isolated environments for testing, running software that the host machine can’t, privacy reasons, and many more. At UGASCS we mainly use VMs to host all of the tools we need for CTFs and other cyber events.
