European Real Estate Listing Company Cuts Costs and Energy Use with Red Hat Solutions

Red Hat, Inc. (NYSE: RHT), the world's leading provider of open source solutions, today announced that ImmobilienScout24, one of the most successful real estate listing companies in Europe serving more than 800 million pages and over three million visitors each month, has achieved significantly reduced energy use and operating costs with Red Hat solutions. Utilizing Red Hat Enterprise Linux Advanced Platform with built-in virtualization capabilities and Red Hat Network (RHN) Satellite, ImmobilienScout24 has cut energy usage by 25 percent, hardware cost per server by 60 percent and operating costs by 10 percent - all while maintaining 100 percent uptime.

Since its website, ImmobilienScout24.de, is the core of its business, uptime and performance are crucial factors for meeting customer expectations. To meet demands, ImmobilienScout24 migrated from a 32-bit Windows server environment to a 64-bit server environment based on Red Hat Enterprise Linux in 2005. As it faced the challenge of scheduled end-of-life for many of its servers in 2008, ImmobilienScout24 planned for a new virtualization initiative to speed provisioning time and reduce overall spending costs. Additionally, the company's datacenter provider broke the news that it was unable to provide any additional power, at any cost, for ImmobilienScout24's servers. Recognizing its rapid growth rate and already challenging power needs, it decided to search for a new vendor that could provide a reliable virtualization solution to help carve out costs and diminish power consumption.

ImmobilienScout24's plan was to reduce its current 200 physical servers down to 90 physical servers with more than 400 logical server instances. In its test lab in Berlin, ImmobilienScout24 worked closely with its operations service provider, Computacenter, to monitor and measure performance of a variety of solutions on both physical and virtual machines.

"We measured the services running on VMware, which typically showed a 20 percent performance degradation compared to services running on the physical server," said Oliver Schindelhauer, head of operations at ImmobilienScout24. "When we tested Red Hat Enterprise Linux Advanced Platform with integrated virtualization capabilities, tests showed only a mere three percent difference between virtual and physical machines, which is an impressive virtualization performance result."

In addition to Red Hat's winning virtualization performance, it also offered cost advantages to ImmobilienScout24. Red Hat Enterprise Linux Advanced Platform includes virtualization built into the operating system at no additional fee, eliminating the need to tack on an additional, and often expensive, third-party vendor solution. Combining performance and cost benefits, Red Hat Enterprise Linux Advanced Platform was the solution of choice for ImmobilienScout24.

The company also utilized Red Hat Cluster Suite, included in Red Hat Enterprise Linux Advanced Platform at no added cost, to create a comprehensive network design that included failover clusters between different physical machines. By carefully designing the clusters and physical and virtual machines, the team created a system that could easily accommodate future growth, while maintaining 100 percent uptime. It also utilizes Red Hat Network (RHN) Satellite to reliably and simply manage the lifecycle of the systems on its network.

The ImmobilienScout24 team began the project in February and was finished implementing its Red Hat solution by May, completely on schedule and with no impact on plattform uptime.

"With Red Hat, we reduced power consumption by 25 percent to 21 megawatt hours per month without affecting performance or uptime. We reduced hardware cost per server by an impressive 60 percent, lowered licensing costs by 50 percent and reduced operations costs with a simplified management solution by 10 percent," said Schindelhauer.

"Without Red Hat solutions, we would not have been able to continue the growth that our executive team planned for the year," said Dr. Oliver Zeiler, CTO of ImmobilienScout24. "But now, we have a significantly more agile and cost-efficient datacenter and services infrastructure. In fact, with the cost savings we've achieved with Red Hat, this project will have paid for itself in three months."
