Containers vs virtual machines
Emberlight Games notices that its containers start in seconds while its virtual machines take minutes. What is the main reason containers are more lightweight than VMs?
- A.Containers always run on dedicated physical servers
- B.Containers cannot store any data
- C.Containers are billed only once per year
- D.Containers share the host operating system kernel instead of each running a full guest OS
Show answer and explanation
Correct answer: D. Containers share the host operating system kernel instead of each running a full guest OS
Why: A VM virtualizes hardware and runs a complete guest operating system, while containers virtualize at the OS level and share the host's kernel, so they are smaller and start faster. Containers do not require dedicated physical servers. They can use attached storage, and billing frequency has nothing to do with startup speed.
