Public cloud adoption has been growing at an unbridled pace over the last decade as organizations raced to move workloads out of on-premise data centers and into the cloud.

Cloud migration was often driven by cloud evangelists, buying into the attraction of exchanging large up-front capital expenditures (CapEx) for pay-as-you-go operating expenditures (OpEx), having better security, simplifying deployment and operations, all for lower overall costs. These promises were mostly met; however, the promise of overall cost reduction has produced mixed results.
