AWS doesn't offer 5-nines uptime on Compute. It's S3 that is 5-nines availability. AWS's published SLA for Compute (which includes EBS) is 4-nines. https://a

- supermatt 5y agoI know they dont, but in the link I gave they tell you how to achieve 5-nines via redundancy - something these cloud service providers (like heroku) neglect to implement.
- terom 5y agoIt's worth noting that the AWS EC2 99.99% SLA is a regional SLA, i.e. it only covers a situation where multiple AZs are down simultaneously. One AZ going down is not covered by the 99.99% SLA. AFAIK there isn't any per-AZ SLA, only a single-instance SLA of 99.5%. The effective per-AZ SLA is going to be somewhere between the two.
