"...In short, Linux yields the most savings, compared with Unix or other operating systems, where Linux servers have a dedicated function, such as Web server, caching or proxy, and where the environment can be replicated over many servers--to hundreds or thousands in a server farm, for example.

That means Linux does best in highly replicated arrangements as a low-end extension to Unix. As the software stack running on top of Linux becomes more complex or comprises commercial proprietary elements, Linux's cost advantage over Unix will shrink.

At Amazon, Hewlett-Packard's Unix OS, HP-UX, still hosts the business-critical database and enterprise applications. It remains unclear whether Linux will maintain similar cost advantages at the high end; Linux could prove even more costly than Unix in these environments, depending on the factors listed above."
