Deploying Virtual Servers
The disadvantages are:
• They require configuration changes on the host computer (configuration of real
or virtual network interfaces)
• They don't scale to configurations with thousands of virtual servers
Both configurations require setting up name-to-address mappings for the three
names. In the IP-address-based configuration, each name maps to a different
address. The host machine must be set up to receive connections on all these
addresses. In the URL-host-based configuration, all names can map to the same
address, the one the machine had originally.
As a footnote, it is also possible to set up the IP-address-based configuration with
one listen socket per address:
