Yep. This seems like the obvious setup to me:
1) make the usual case as economical as possible (and ownership and the associated control will probably help here, unless you have to lease the expertise too)
2) outsource the exceptional case (ownership is less likely to matter here, and will matter for less time even if it does)
- freedomben 5y agoThis is exactly what many of the really big enterprises do. At their scale the cloud becomes laughable. But as a backup, it's the clear way to go. Primary on prem with automatic failover to the cloud. I worked with a large customer to help build this for them. OpenShift running on-prem, but they had some failover equipment that would ansible them an OpenShift cluster on aws. Depending on the nature of the failure it did take a little time to fail over, but 15 to 30 mins of downtime in the event of a catastrophic failure is often worth it to save hundreds of millions per year.
