A company wants to optimize cloud resources and lower the overhead caused by managing multiple operating systems. Which of the following compute…

Containers are the best choice to meet the company's goals. They provide operating-system-level virtualization where multiple containerized applications share the host operating system's kernel. This design significantly lowers the overhead associated with managing multiple operating systems because there is only one host OS to patch, license, and maintain. Furthermore, because containers do not bundle a full guest OS, they are more lightweight and consume fewer resources (CPU, RAM, storage) than virtual machines, directly contributing to the optimization of cloud resources.

A. VM: A virtual machine (VM) encapsulates a full guest operating system, which increases management overhead and resource consumption, directly contradicting the stated goals.

C. Remote desktops: Remote desktop solutions are typically deployed on top of VMs, inheriting the same high overhead for OS management and resource usage.

D. Bare-metal servers: While eliminating hypervisor overhead, this option does not inherently optimize resource usage for multiple workloads and still requires managing a separate OS for each server.

" it states

"Unlike virtual machines

containers don't include a guest operating system in each instance. Instead

they use the features and resources of the host operating system... This makes containers more lightweight and portable."

2. Amazon Web Services (AWS) Documentation. (n.d.). What is a Container? AWS. Retrieved from https://aws.amazon.com/containers/. The documentation explains

"Unlike VMs

containers do not bundle a full operating system—only the libraries and settings required to make the software work. This makes them efficient

lightweight

portable

and scalable."

"Understanding Containers

" contrasts containers with VMs

noting

"Instead of virtualizing the underlying hardware

containers virtualize the operating system... Because containers share a single operating system kernel

they are much more lightweight than virtual machines."

"Containers: Lightweight Virtualization." The slide deck compares VMs and containers

highlighting that containers "Share kernel with host" and have "Lower overhead

" which directly supports the reasoning for selecting containers for resource optimization and reduced management.
