Infrastructure as code requires that teams have the ability to use scripts to automatically provision resources and custom fit it to their needs, instead of having centralized teams act as gatekeepers. Provisioning a machine should not require any human involvement; there should never be a need to create a ticket or a change request, and provisioning requests should be handled within minutes at most. As Carla Geisser from Google put it: “If a human operator needs to touch your system during normal operations, you have a bug.”

If your IT department claims to have self-service capability but still requires days or weeks for approval and provisioning, it’s quite likely that either an overly rigid cloud provider agreement, a threadbare resource pool, or antique Iron Age manual processes are holding them back. These need to be reexamined for infrastructure provisioning to be truly on-demand and able to keep up with the pace of application development.
