You probably know way better than me, but in my experience, configuring things correctly on healthy hardware gets you 99.99% by default. Adding some surplus capacity adds another 9, at least.
Then you build from there (autoscaling, hardware failovers, etc. etc.).
- lelandbatey 2y agoEh, 99.99 is less than an hour downtime a year. I know of almost nothing of any size that actually achieved that save certain areas of the power grid.
- andrewaylett 2y agoThat does depend somewhat on what you count as "downtime". Larger distributed systems may not suffer a complete outage in the whole year, and more than one of the services my team runs has that level of successful response ratio.
