What is Cloud Computing? Flashcards
What is cloud computing?
Remote virtual pool of on demand shared resources offering compute, storage, database, and network services that can be rapidly deployed at scale
How many VM’s does virtualization allow on 1 physical server?
Multiple
Each VM has it’s own what?
Operating System and Applications
Do VM’s have to share hardware resources?
No, they can run at the same time.
How is virtualization (VMs) achieved?
Hypervisor
Explain the purpose of a Hypervisor
Any request to the hardware goes through the Hypervisor that handles access. It ensures hardware resources are shared between all other VMs as needed and configured.
What are the benefits of Virtualization?
Reduced capital expenditure
Reduced operating costs
Smaller footprint
Optimization of resources
A VM within a public cloud is referred to as…
an instance
Compute provides…
the brains to process your workload
Give a comparison of a classic environment of Compute.
Hardware devises with CPUs and RAM and how they work in a classic, on-premise environment
Storage allows….
for saving and storing data.
Give a comparison of a classic environment of Storage.
Server hard disks or Network attached storage (NAS) and high speed Storage Area Network (SAN)
What do databases allow?
They allow for storage of structured sets of data used by applications.
What are the common database engine types used in data center?
