Citrix XenDesktop is a form of desktop virtualization that enables fully personalized desktops for each user that can be managed from a centralized location.
With the intregration of Citrix XenApp we can also deliver on-demand applications to any user anywhere. This allows users to access desktops and/or applications
from any computer or phone and use them like they were here at the a agency. (Read More...
- Cuts out hardware cost by using Thin Clients
- Eases management of users/desktop/applications
- Makes helping remote users easier and faster
- Applying updates or installing applications quicker to multiple users
Thin Client help our Citrix environment by serving as a dummy terminal. In order to access XenDesktop you must have
some sort of laptop, PC, or phone to use to connect to the server with. Our Thin Clients run Windows XPe and save us
- Being cheaper than a standard laptop or PC
- Lasting longer due to no moving parts (less hardware to go wrong)
- Being more durable
How we use Citrix
Currently the Arkansas Department of Emergency Management uses Citrix for the State Emergency Operations Center.
Using Citrix Provisioning Services we are able to create one vDisk (virtual disk) and deploy it to multiple computers
within the SEOC. This ensures that each user logging into the SEOC is getting the same image as everyone else. Everything that a user does once logged into the VM (virtual machine) is written to
a write-cache on the server. This means that other users cannot see what another is doing and also keeps our image from
changing. Once the user logs off all of their changes are erased and reverted back to normal.
With Citrix desktop virtualization ADEM is ready to function anywhere at any time.
Our users have the ability to have an assigned desktop that is all their own.
They can access this desktop from any terminal that has an internet connection from anywhere in the world.
When they login through a web interface, it is like they never left the office.
They are able to perform their duties just as they would sitting in the State’s Emergency Operations Center.
Before Citrix Virtualization
Before Citrix we had Gateway laptops in the SEOC. This had many downfalls such as:
- Hardware failure (normally resulting in replacing laptops every three years)
- Batteries going bad due to always being on a charger
- Any modifications had to be duplicated 30+ times (due to not being a shared image)
- Machines becoming slower overtime
- Roaming profiles being saved to local hard drive
