Because Cloud Service Consumer A's response message is processed by two separate cloud services, the combined availability increases as follows: 1 - (1 - 0.95) X (1 - 0.95) = 0.9975 or 99.75%

Because Cloud Service A acts as both a cloud service and cloud service consumer in order to process Cloud Service Consumer B's request message, Cloud Service A forms a dependency on Cloud Service B. As a result, the combined availability decreases, as follows: 0.95 X 0.95 = 0.9025 or 90.25%

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%

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%

Redundant implementations of Cloud Service A are deployed in all three clouds. The failover system mechanism and a special type of automated scaling listener mechanism are implemented to establish a system whereby one redundant Cloud Service A implementation will automatically take over from another.

A cloud balancing solution is established, whereby an automated scaling listener mechanism is implemented on each cloud in such a way that every cloud can automatically scale out to another cloud. As a result, if reliability problems occur on any one cloud, the subsequent requests will be scaled out to another cloud in a manner that is transparent to cloud service consumers.

A failover system mechanism is implemented on Cloud X, which acts as the primary point of contact for cloud service consumers. Upon failure conditions occurring, the Cloud Service A implementation on Cloud X automatically hands over control of current and future message requests from cloud service consumers to Cloud Y. Cloud Y retains control of cloud service consumer communication until the next failure condition occurs, at which point it hands over control to Cloud Z. Finally, if a failure condition occurs in Cloud Z. control is handed back to Cloud X.

A cloud balancing solution is established, whereby a resource replication mechanism is implemented on each cloud. This allows Cloud Service A to be automatically replicated across cloud environments, thereby enabling each implementation of Cloud Service A to take the place of another, whenever failure conditions occur.
