LinchPin is a simple and flexible hybrid cloud orchestration tool. Its intended purpose is managing cloud resources across multiple infrastructures. These resources can be provisioned, decommissioned, and configured all using declarative data and a simple command-line interface.
Linchpin recently release 1.5, and I had an opportunity to talk with Clint Savage earlier this week about Linchpin and what it offers the world.
