Cloud & DevOps question 27
A request must pass through a web server and then a database server, and both must work for the request to succeed. If each has 99% availability and they fail independently, what is the availability of the whole system?
- 99%
- 99.99%
- 99.5%
- 98.01%
Answer and explanation
Answer: D. 98.01%
Explanation: Components in series multiply: 0.99 × 0.99 = 0.9801 = 98.01%. 99.99% would apply to two redundant components in parallel, where only one needs to work.
