Citrix and Amazon are teaming up to put Citrix's application delivery software into the cloud, letting enterprises stream apps to users from Amazon's datacenters.
The companies announced a pilot program to run XenApp on Amazon's Elastic Compute Cloud service.
"Virtualizing applications provides IT managers a single instance of each application in either the datacenter or the cloud (i.e., EC2)," Citrix CTO Simon Crosby writes in a blog. "Applications are then delivered via application streaming directly to Windows devices for both online and offline use."
The pilot will let Citrix customers move their XenApp licenses from their own data centers to Amazon EC2 and "run their applications in a fully supported environment," Citrix says. However, eligibility is restricted to Citrix customers who are also members of Amazon's Windows Server License Mobility Pilot, which allows migration of Windows Server licenses to Amazon EC2.
The XenApp/Amazon pilot also does not yet support Amazon's Virtual Private Cloud, which is designed to bring enterprise-class security to computing resources that run in Amazon's data centers.
"Citrix is continuing to work with Amazon on plans to incorporate VPC into the Citrix Pilot at a future date," Citrix says.
The pilot is therefore of limited use today, but potentially interesting to businesses considering whether to eventually offload internal IT infrastructure to a cloud provider. With XenApp running in Amazon EC2, a business could substantially reduce the number of physical servers it has to manage.
On Amazon, "With a single API call you can create a 1TB SQL database that has a 15 day, up to the second granularity of transactional roll-back, that is continually backed up and available,"
Customers still must carefully evaluate infrastructure-as-a-service clouds to make sure a particular application can be supported, he writes.
"What matters most is to evaluate the capability set of a particular IaaS cloud vendor, and map it to the requirements of your enterprise applications,"
