alt Hacker NewsAnyone who thinks one cloud provider will provide them full resilience is fooling themselves. You need multicloud for true high availability.
But then you want to use the same stack across providers and all the proprietary technologies (even hidden from you with things like terraform) are suddenly loosing their luster.
I don’t think any actually believes that.
What people usually think is “resilience up to a reasonable level of risk and cost”.
Multi-cloud is simply isn’t cost beneficial for 99.9% of problems.
And for a lot of businesses who talk about risk, saying “we followed AWS best practices but AWS went down” is an acceptable answer to the question of liability.
If you are in a position where AWS going down is a reasonable risk, then you’re already in a specialised enough domain to have engineers who understand how to deliver HA across different vendors.
