CIOs may have grumbled when Amazon Web Services experienced an outage of 8 hours in December 2021. But their early scramble to build failovers to alternative cloud providers stalled when they found out what it would cost in capital spent and technological complexity. Today, CIOs and other IT leaders have gained a more sophisticated understanding of the tradeoffs between resilience and cost. You get what you pay for, and if your cloud outage isn't impacting revenue, you may be able to wait a few hours for the cloud service to be restored. On the other hand, if you are a major retailer and it's Christmastime, an outage of 8 hours could cost millions of dollars. As a CIO, architecting for resilience will depend on what business you are in, what you use the cloud for, and where you are in the world.
