Our point of comparison was VMS, which is a very mature operating system. Foster adds that Microsoft Exchange scales in a number of ways. Perhaps equally important, our experience indicates that Microsoft Exchange is essentially infinitely scalable horizontally. We've had absolutely no trouble adding servers to our growing network. When considering scalability, issues such as the number of users per server or the number of messages per second are not the only concerns.
Scalability also involves administrative demands.
Microsoft Exchange gives us a very feature-rich product for end users. It uses modern, consistent interfaces and protocols that can be quickly mastered. Specifically, Digital appreciates how easy it is to configure servers, add users, reassign users and administer all users from a central point. Our users like Microsoft Exchange for its ease of use and rich content messages. Because of these capabilities, Digital was able to migrate to Microsoft Exchange without adding internal operations staff.
