CI Requires Extra Hardware

As discussed earlier in the section Dedicated Build Servers,” CI works best with a powerful computer dedicated to performing builds and all the associated tasks. Although CI can be implemented without a dedicated build server, the benefits generally outweigh the costs of extra hardware, even when the machine is a very powerful (i.e., expensive) one. Even so, there are at least two ways to get started with CI on something less than the biggest, fastest machine on the market: piggyback on an existing server or use a less powerful machine that no one wants.

Piggybacking on an existing server or shared computer, such as a test machine or an underutilized web server, is a quick way to implement CI. Such machines are often already running the typical deployment environment, so you only have to load the CI-related software. When following this approach, the more stable the environment, the better. A server whose configuration is changed often will lead to inconsistent build results.

Implementing CI on a less powerful machine—perhaps one left over from the last time the development machines were upgraded—provides ...
