LONDON 28 October 2011 – INTERXION HOLDING NV (NYSE: INXN), a leading European provider of carrier-neutral colocation data centre services, today announced the deployment of its second Cloud Testlab, a turnkey cloud hosting test environment enabling service providers and system integrators to test and develop cloud services at high speed and with best-in-class performance guarantees.

This Testlab deployment is a collaboration between Interxion, Flexiant, Boston Limited and GTT and acts as an online proof-of-concept (PoC) environment for cloud service providers. It can be used for testing scenarios before deploying a cloud infrastructure with the proof-of-concept being run on a reference architecture. This Testlab offers a framework that supports multiple hypervisors and allows service providers to build both private and public clouds.

The new test environment is located in Interxion’s City of London data centre and will deploy Flexiant’s Extility platform solution, have network connectivity via GTT and be housed on Supermicro® hardware provisioned by Boston Limited. From 17 November 2011 onwards, users can access this Cloud Testlab deployment online via [http://www.interxion.com/cloudtestlab/UK] and test the PoC free of charge for a limited period.

Greg McCulloch, UK Managing Director, Interxion, commented, “The rapid adoption of cloud computing has seen cloud-based services become a central part of business strategy. The launch of this UK Cloud Testlab deployment further reflects our commitment to the cloud and offers both customers and prospects the opportunity to test and develop cloud services at high speed and with best-in-class performance guarantees.”

“Flexiant enables hosting companies to compete in the cloud computing virtualisation sector on a level playing field with global market leaders who have proprietary, rapid-provisioning infrastructures,” said Robert Karssiens, Director Sales & Marketing at Flexiant. “Extility is a proven, credible and visionary alternative to the cost of developing a cloud computing platform in-house with real time user interface and in-built billing engines capabilities.”

“We are delighted that Interxion has chosen Boston Limited and Supermicro® as hardware providers for the launch of this Cloud Testlab,” said Manoj Nayee, Managing Director of Boston Limited. “Boston Limited has been developing high performance, energy efficient solutions in conjunction with Supermicro® for nearly 20 years, and our latest offerings for the cloud arena incorporate advanced software features to create Enterprise class solutions, giving your business the ability to scale processing capabilities that mirror your exact requirements to save you space, power and money.”

“Network connectivity is a key, but often forgotten, building block for cloud computing” said Andy Johnson, Chief Strategy Officer of GTT. “Our reliable and scalable bandwidth solutions deliver the performance demanded by the end users in accessing a cloud computing environment, ensuring the benefits of such services are not hindered by poor usability. Our goal is to design network solutions that allow the Enterprise to access public, private and hybrid cloud solutions in a way that enhances the capabilities and benefits of them, rather than allowing the network to be the bottleneck. The UK Cloud Testlab is an excellent concept and we are pleased to be working with Interxion.”
