4. What is Virtualization?
“…Creating a simulated version of hardware platforms, operating systems, storage devices, and computer network resources.”
Centralize administrative tasks while improving scalability and workloads.
3 Types:
Network
Storage
Server
Why?

5. Consider This…. Hardware Compatibility Oversubscription/Performance
BIOS settings – support virtualization
Oversubscription/Performance
Virtual machines run in a "layer" on a host system
There will always be some level of performance sacrifice
My advice…before you
buy, virtualize something!
Compatibility – Servers need to be consistent with similar specs – server needs to be able to support virtualization (BIOS Settings)
Oversubscription/Performance – always some sacrifice to performance

6. Picking a Platform Linux Windows Server VM Ware Citrix Hyper-V
What you select what to install is determined by what type of environment that you are using. Once you install one you are going to have the GUI of the platform that you select.
One pro Linux has over Windows is that it has less overhead. Windows Server takes up resources in order to run leaving less to run your virtual machines while requires fewer resources to run.

7. Benefits of Hosting
It’s easy! You don’t have to worry about managing the server, creating users, updates, security, backups, or hardware upgrades
