Load Testing · Senior · Question 7 of 76
How should you size capacity for a service in three availability zones?
- 1So one zone alone can handle three times the peak
- 2So two zones can handle the peak if one zone fails
- 3So each zone handles one third of the peak, with no margin
Show the answer
Correct answer: So two zones can handle the peak if one zone fails
Explanation
N+1 thinking: losing a zone moves its traffic to the others. Load tests should check that the remaining capacity holds that load.
