Hello
I have experience designing, building and maintaining a large (1000 user +) Citrix XenDesktop/App farm in AWS, we were using XenDesktop 7.15, MCS for provisioning, ONTAP for profile storage (were looking to migrate to s3 with liquidware profiles direct to s3) Virtual Netscaler appliances etc.
I have a lot of depth in most all of the supporting infrastructure and was the lead engineer for the AWS environment.
I would be happy to share my experiences and help you with this project.
Thanks
Callum
