Enterprise Web hosting split fairly evenly between data centers and shared hosted servers

According to BZ Research, 42.0% of enterprise Web sites are hosted within their internal data centers, while 40.6% are hosted externally using shared servers owned by the Web hosting company.

Those were by far the dominant findings in our first-ever Web Hosting Study, completed in October.

Those numbers swamped the use of Web servers hosted on departmental servers outside the data center (22.0%), hosted externally using dedicated server owned by the host (20.8%), and those hosted externally using company-owned servers in colocation facilities (13.0%).

The last number was the most surprising to me. Frankly, I expected colo-based Web hosting to be more popular.

The complete study, which digs more deeply into the topic, is available from BZ Research.
