Multi-Cloud Versus Single Cloud, Multi-Region
TradeoffPrincipalUpdated
After a regional outage at your only cloud provider, the board asks for multi-cloud. You have 400 engineers, deep use of managed services, and no regulatory requirement for a second provider.
Short answer: Single Cloud, Multi-Region. Spread across multiple regions of the provider you already use, which addresses the outage that actually happened at a fraction of the cost.
The Two Options
A
Multi-Cloud
B
Single Cloud, Multi-Region
Drill This: Your Pick First
The Better Pick
Option B
Single Cloud, Multi-Region
Spread across multiple regions of the provider you already use, which addresses the outage that actually happened at a fraction of the cost. Multi-cloud means trading managed services for lowest-common-denominator tooling or building everything twice, and it doubles the expertise every team needs. Regional failures are far more common than a whole provider going down.
When the Other One Wins
Multi-Cloud
When a regulator requires an exit plan, or large customers require you to run in their cloud, a second provider becomes a business requirement worth the cost.
