Citrix XenServer to Power 1&1 Internet Global Cloud Platform


Citrix today announced that leading Web hosting provider 1&1 Internet has designed its public cloud offering, Dynamic Cloud Server, on Citrix XenServer® technology, demonstrating significant momentum for the rapidly growing Citrix Cloud Platform Business.

Fueled by the strong leadership and rapid adoption of open source Xen technologies, 1&1 Internet has strategically adopted Citrix technology for its public cloud computing solution. Citrix XenServer is now powering cloud services for four out of five of the world’s largest hosting providers.

With 11 million customers supported by five highly secure green data centers across Europe and the U.S., 1&1 Internet selected XenServer to provide a flexible infrastructure from which to launch its public cloud services. XenServer will make it possible for the global hosting company to deliver granular control of server resources using a proven cloud-ready virtualization platform to meet customer price, performance and scalability requirements.

1&1 Internet created its Dynamic Cloud Server on XenServer technology due to

  • product maturity
  • open source code-base
  • flexible pricing model
  • Citrix worldwide support and services

XenServer is a complete server virtualization platform built on the powerful Xen hypervisor. Xen technology is widely acknowledged as the fastest and most secure virtualization software in the industry and is designed for efficient management of Windows® and Linux® virtual servers, delivering cost-effective server consolidation and business continuity.

XenServer serves as the virtualization platform of choice in a majority of the public clouds today. 1&1 Internet joins an impressive list of large cloud service providers that utilize Xen/XenServer technology including Amazon, and other private and public cloud offerings.
