One of the more fun projects of the last ten years was a project designed to fail. We had an in-house data centre, and we needed more capacity at certain times of the year. Justification was needed for more dedicated capacity in the face of cloud infrastructure. So we built a system to use spot pricing to spin up extra instances, securely, on AWS, google cloud or azure. This could meet bursts of demand at busy times. At the end of the exercise we had a working system and managed to prove it was better value and more resilient for the organisation to increase on-premises capacity. Fun project though!
