When you search megabytes of logs file for a clue what went wrong, or when you want to generate some statistics, you realize that this calls for proper tooling.

As an initiative to get developers, sysadmins, and testers working together to increase the speed of delivering high quality software changes, a key challenge devops must address is trust. Sysadmins simply don’t trust developers to hand them production ready code.

Hosted applications need to be upgraded regularly. Configuration changes are regularly needed to tweak the environment so that it runs efficiently and communicates properly with other systems. This requires some mix of command-line invocations, jumping between GUI screens, and editing text files.
