Page 85 - Containers: Containers are code execution environments that run within an operating system (for now), sharing and leveraging resources of that operating system. While a VM is a full abstraction of an operating system, a container is a constrained place to run segregated processes while still utilizing the kernel and other capabilities of the base OS.

A. True The statement is true. A virtual machine (VM) is a full abstraction of an operating system, where each VM includes its own complete operating system instance along with virtualized hardware. On the other hand, a container is a more lightweight form of virtualization that provides a constrained environment to run segregated processes while sharing the same kernel and OS capabilities. This enables containers to be more efficient in terms of resource usage compared to full virtual machines.
