looking at the uptime from aws and from most big outtage notices i have read in the last few years, there does not seem to be a benefit in regards to reliability when using cloud.

see reddit, see amazon/aws outages taking with them netflix/disney plus etc

honestly its a lot better to keep your architecture cloud agnostics and test restores regulary on a different provider/region

also: store your backups somewhere else, not on your primary cloud provider, not connected to your auth system, not overwritable from anywhere

I am not aware of an AWS outage in their 15-16 years of existence, that an architecture, built according to the recommended best practices, of distribution across availability zones and regions, would not be able to withstand. I am willing to be proven wrong. Can you provide one example?

Of course, these come with increased cost, but I am thinking web retail on a large scale, or airline companies, where for example a downtime of a few hours will easily wipe out any savings made by relying on a local data center. It might not be the solution for a smaller company.

I guess you did not have any service running on aws winter 2021? Does not really matter which region, with certain services you could get lucky but basically everything depending on fresh iam creds was down

And if netflix/disney/slack/ring amazon themself can not do it, with a multiple with the ressources i have access to, good luck to you.

there are also times where your company might rely on a single aws product, and it might simply break an integration(aws iot mqtt ->sqs for example) took them 2 days to fix
