Red Hat Linux Powers Google's Award-Winning Search Engine

RESEARCH TRIANGLE PARK, N.C.—May 30, 2000—Red Hat®, Inc. (Nasdaq:RHAT), a leader in open source Internet infrastructure solutions, today announced that its operating system powers Google's Internet search engine services. Google, one of the fastest growing search engines on the Web, operates its search engine and all of its computing functions on a cluster of more than 4,000 PCs running Red Hat. Google plans to significantly increase its use of the Red Hat Linux operating system as it increases its computing power to meet the growing demand of users worldwide.

Google has used Red Hat Linux for all its Internet computing functions since its inception in 1998. To generate the necessary power for its in-depth searching capabilities, Google needed a large cluster with the dependability and scalability of UNIX, but without the prohibitive cost. With the support of Red Hat, Google has seen significant success. To match the site's growth, Google has scaled its current Linux cluster to more than 4,000 computers, and plans to increase this number as the site's popularity continues to grow.

"Red Hat's easy installation, reliable operating environment, and scalable server support cut down the time and person power needed to oversee the thousands of Internet servers in the Google Linux cluster, thereby helping Google to maintain its focus on developing new technologies that improve a user's search experience," said Urs Hoelzle, Google's vice president of engineering.

Unlike other Internet search engines, Google combines an easy-to-use interface with complex algorithms to determine the importance and relevancy of Web pages — a task that requires a high-performance back-end system.

Google will continue to deploy the Red Hat Linux operating system as more computing power is needed to answer search queries and handle growing worldwide traffic. Red Hat provides the high-performance Linux software necessary for processing and retrieving search queries across all Google data centers.

"By successfully utilizing one of the world's largest Linux clusters, Google has proven Red Hat's scalability and reliability for mission-critical Web solutions," said Billy Marshall, VP of Product Marketing, Red Hat, Inc. "As Google grows, Red Hat will continue to provide the power and support that its innovative searching technology requires."

"IDC's studies show that Linux is often used to support Web infrastructure," said Dan Kusnetzky, vice president, IDC. "By using Red Hat Linux to power its Web searching service, Google is taking advantage of the flexibility and power of Linux. The growth of paid shipments of Linux as a server operating environment has been impressive. It's grown faster than any other server operating environment between 1997 and 1999."

Open source momentum
International Data Corp. (IDC) research states that paid Linux shipments grew faster than any other server operating system over the past two years, and their preliminary figures for 1999 show Linux shipments hold 24.6 percent of the server operating system market, up from 15.8 in 1998. IDC also states that Red Hat Linux is by far the most popular distribution, preferred by 68.7 percent of U.S. Linux users.

Research firm Netcraft, Inc. (www.netcraft.com), states that as of May 2000, 36 percent of all public Web sites run on Linux-based operating systems, making Linux the most popular choice for deploying public Web sites. IDC research shows 40 percent of all spending on Linux servers is for Internet related applications, firmly entrenching Linux servers in the Internet infrastructure.

Finally, IDC predicts that by 2002, there will be more than 55 million handheld and notebook-style information appliance devices and that by 2005, shipments of these appliances will exceed shipments of PCs.

Red Hat's numerous alliances with industry leaders and the demand for Linux-based applications has created open source support from many of the industry's leading software and hardware manufacturers, including Compaq, Computer Associates, Dell, Hewlett-Packard, IBM, Intel, Netscape, Novell, Oracle and SAP.
