A container is the same as a virtual machine

Explanation

• Containers share the same operating system and kernel as the host that they exist on. But virtual machines contain their own operating system. Each virtual machine must maintain a copy of an operating system, which results in a degree of wasted resources.
• A container is more lightweight. Containers spin up quicker, almost instantly. This difference in startup time becomes instrumental when designing applications that must scale quickly during I/O bursts.
• Containers can provide speed, but virtual machines offer the full strength of an operating system and more resources, like package installation, dedicated kernel, and more.
