Not SQS, but Google PubSub: everything was working allright, until one day messages started arriving with horrible latency and vital parts of our service went down. We spent close to two weeks debugging our infrastructure, because _sure it could not be PubSub_. Well, _it was_. I guess nothing too big, a small bit or tweak that changed in their service that didn't propagate to the client library we were using, or god knows what. Now we run RabbitMQ for everything; at least we control our versions and we can confidently blame ourselves when something happens. But RabbitMQ, standalone and clustered, has served us well across different systems for about fifteen years.
