SLA Calculation Exercise
20 minOnce
Format: Understand what "nines" mean in an SLA (Service Level Agreement).
| SLA | Availability | Allowed Downtime/Year | Allowed Downtime/Month |
|---|---|---|---|
| 99% | 2 nines | 3.65 days | 7.31 hours |
| 99.9% | 3 nines | 8.77 hours | 43.83 minutes |
| 99.99% | 4 nines | 52.6 minutes | 4.38 minutes |
| 99.999% | 5 nines | 5.26 minutes | 26.3 seconds |
Think about it: How many nines does your app need? A personal project might be fine with 99%. An e-commerce site during a major sale might need 99.99%.
