Spotify hits the G-Spot, leaps into Google's cloud

Re: What about redundancy and DR ?

Many SMEs do indeed blindly trust in one platform provider, but in Spotify's case I suspect it's a calculated business risk. Google is less likely to go bankrupt than Spotify, so they probably won't disappear overnight. The cost of downtime is a known factor as is the cost of using multiple providers. Given the dependence on proprietary Google tools, having a second provider would involve a complete port of the system to another set of tools. I imagine the cost of this massively outweighs the cost of projected downtime.

Downtime in itself is not necessarily an evil. The cost of five nines often outweighs the business advantages of doing it.

"Cloud has demonstrated that there is no vendor that can boast 100% uptime"

I can't think of any multi-region AWS outages. Realistically almost all people will find multi-region gives them as good an uptime as they'll ever need.

Multi-provider is hard because the cloud vendors are all trying to lock you in/improve interoperability between their products. There is a massive amount of work in abstracting away the differences and it limits flexibility to the extent that everyone I know that's tried it has given up. Multi-region is also hard because of the architectural challenges but worth it for someone like Spotify (for at least some features).

People will do hybrid models - cloning s3 to Google storage for backup is a common one (and that also allows use of Google's bigquery stack)

I thought Spotify used P2P?So wouldn't need to worry so much about eggs and baskets.
