95 X 0.95 = 0.9025 or 90.25%

95 X 0.95 = 0.9025 or 90.25%

C. Cloud Service Consumer A benefits from redundant cloud service implementations, thereby increasing the guaranteed availability as follows:

1 – (1 – (0.95 – 0.1))X (1 – (0.95 – 0.1)) = 0.9775 or 97.75%

D. As a result of the dependency formed by Cloud Service Aon Cloud Service B,the combined availability decreases significantly as follows:

(0.95 X 0.95) – 0.1 = 0.8025 or 80.25%
