That??™s why most large companies converting to open source infrastructures have gone with products
from enterprise Linux providers, such as Red Hat, Inc. (Red Hat Enterprise Linux) and Novell,
Inc. (SUSE Linux Enterprise).
Built into Red Hat??™s open source enterprise products are features such as Red Hat Directory Server,
Global File System (GFS), and Cluster Suite. Directory Server can scale up to handle millions of
identities, representing settings for applications, user profiles, access control, and policies across
thousands of machines and users. Using GFS and Cluster Suite, an enterprise can treat its entire
storage infrastructure as a common pool to minimize data duplication and simplify backups, system
recovery, and adding storage and servers.
Companies moving their infrastructures to Linux include Apoteket (Sweden??™s government-run
pharmacy), which is moving more than 900 pharmacies to Red Hat Enterprise Linux (RHEL)
on Intel servers. Governments that are migrating to RHEL include cities such as Chicago and
Bloomington, Illinois. You can read about other organizations migrating to RHEL on Red Hat??™s
Success Stories page (www.redhat.com/solutions/info/casestudies).

all the terrible things it could lead to or, conversely, to almost manic declarations of how Linux will
solve all the problems of the world.
