Isn't it everyone using multiple cloud providers nowadays? Why are they affected by single cloud provider outage?

[lvncelot]

I think more often than not, companies are using a single cloud provider, and even when multiple are used, it's either different projects with different legacy decisions or a conscious migration.

True multi-tenancy is not only very rare, it's an absolute pain to manage as soon as people start using any vendor-specific functionality.

No, that's pretty rare, and generally means you can't count on any features more sophisticated than VMs and object storage.

On the other hand, it's pretty embarrassing at this point for something as fundamental as Docker to be in a single region. Most cloud providers make inter-region failover reasonably achievable.

[roywiggins]

You can be multi-cloud in the sense that you aren't dependent on any single provider, or in the sense that you are dependent on all of them.

[postexitus]

Not only they are not using multiple cloud providers, they are not using multiple cloud locations.

[rcxdude]

Because it's hard enough to distribute a service across multiple machines in the same DC, let alone across multiple DCs and multiple providers.

[pmontra]

Because even if service A is using multiple cloud providers not all the external services they use are doing the same thing, especially the smallest one or the cheapest ones. At least one of them is on AWS East-1, fails and degrades service A or takes it down.

Being multi-cloud does not come for free: time, engineers, knowledge and ultimately money.

[DiggyJohnson]

Multi cloud is not nearly as trivial as often implied to implement for real world complex projects. Things get challenging the second your application steps off the happy path

No? I very much doubt anyone is doing that.

> Isn't it everyone using multiple cloud providers nowadays?

Oh yes. All of them, in fact, especially if you count what key vendors host on.

> Why are they affected by single cloud provider outage?

Every workload is only on one cloud. Nb this doesn’t mean every workflow is on only one cloud. Important distinction since that would be more stable.

[madisp]

they are using multiple cloud providers, but judging by the cloudflare r2 outage affecting them earlier this year I guess all of them are on the critical path?

[nobleach]

Looking at the landscape around me, no. Everyone is in crisis cost-cutting, "gotta show that same growth the C-suite saw during Covid" mode. So being multi-provider, and even in some cases, being multi-regional, is now off the table. It's sad because the product really suffers. But hey, "growth".
