bstraction is the concept of dividing specific functions of a server into their own individual systems. Much like subcontracting janitorial, or security services out for a building owner.

Virtualization

Compute – Provided by hardware with Hypervisor software installed
Storage – SAN’s or other storage service store the data and virtual machines
OS – Operating Systems are installed in Virtual Machine files that can be moved like any other file
DRaaS – Services such as Disaster Recovery are provided by online services
SDN – Software Defined Networking

Hardware – Routers, Switches and other networking equipment is “dumb” and receives all configurations from a Management Server
Management Server – manages all rules, logs, and controls network devices
Rules – written in Python or other languages the rules can offer fine tuned configurations that can route traffic by individual devices, users, and even based on outside conditions.
Serverless Architecture

Code – is stored on a basic server and makes calls to other services
Compute – services are now accessed without dealing with the underlying Operating Systems. You call an “encode” service that encodes your video instead of dealing with a Windows Server with ffmpeg.
Storage – is simply a bucket offered by AWS or AZURE
Authentication – even services such as authentication can be made through API calls instead of dealing with Active Directory.
