XenApp Best Practice #1: For the best user experience, application and back-end data must reside together on a fast, low latency network.
What if you decided to store your cooking pots and pans in the bedroom? Every time you wanted to cook some Mac & Cheese, you would have to walk through your house, maybe up the stairs and into the bedroom to grab a pot. Then you walk back through your house into the kitchen to start cooking. And if you are like me, in the middle of cooking your delicious Mac & Cheese you realize you need another pot, so again, you walk back through your house, up the stairs, to the bedroom to grab the next pot, and then you walk back downstairs into the kitchen.
This would be a horrible experience (although it might solve obesity problems with all of that extra exercise).
So, tell me why you would want to have your data far away from your applications? You wouldn’t, right? But I’ve seen so many do it.
Let me give you some examples:
- Exchange Online: If I have a local install of Outlook, my application data is somewhere in the cloud.
- Hybrid Cloud: We host an application in the cloud while leaving our data residing in our data center.
For the best user experience, your applications and back-end data must reside together on a fast, low-latency network.
This is one of the fundamental XenApp best practices.
- Look at Citrix ShareFile. In the XenApp/XenDesktop world, we locally sync what you are currently trying to access.
- For Exchange Online, only sync the most recent email, as it is the data you will most likely access. (Take a look at the Office 365 Deployment Guide for additional design recommendations.)
- For XenApp, host applications in the right data center or cloud provider where your application data resides. If this means you have XenApp hosts in multiple locations, so be it because you can use the Applications and Desktop Service of Citrix Workspace Cloud to integrate all of these sites together into a single management plane.
- And for your home, keep your pots and pans in the place you will use them… in the kitchen.
Stay tuned for more best practices …
