Is Amazon comfortable enough to create single point of failure. What if DDB goes down assuming they run same stack for both retail and AWS?

- yeukhon 9y agoThey introduce change one region at a time usually. DDB did have outage many times and brought half of AWS operations down. But good question how they kept Amazon.com alive if some part of their systems rely on DDB. [1]: https://aws.amazon.com/message/5467D2/ https://aws.amazon.com/message/5467D2/
- phamilton 9y ago> What if DDB goes down It's worth clarifying that question. What does "Go Down" mean? One region is down? Is it a bad software bug? The database itself is fault tolerant. Nodes can go down all day without any real consequence. Each region is isolated, so a failure in one region won't affect other regions. I guess I'm at a loss for the type of failure with DDB that would make it a SPOF, especially more than other datastores.
- dx034 9y agoHow do they structure regions? Is amazon.co.uk running on different regions than amazon.com? Or everything distributed globally?
