Which of the following statements describes a solution that solves this problem for Cloud Service Consumer A by improving both Cloud A and Cloud B environments?

Question

Cloud Service Consumer A accesses Cloud Service X (1) that resides in Cloud A. Cloud Service X processes the request from Cloud Service Consumer A and then sends back a response with the requested data (2). Cloud Service Consumer A then sends a message to Cloud Service Y (3) that resides in Cloud B. The message contains some of the data received from Cloud Service X. After processing the request, Cloud Service Y sends back a response with a success or failure code (4).

Cloud A is a private cloud owned by the same organization that owns Cloud Service Consumer A. Cloud B is a community cloud owned by a group of organizations. The availability rating of Cloud Service X, as indicated in its SLA, is 99.98%. When Cloud Service Consumer A issues a request message to Cloud Service X, it can result in prolonged processes as Cloud Service X attempts to gather the requested data from various data sources. Because Cloud Service X is shared by other cloud service consumers and because the data sources are also shared by other parts of the o

Answer 1

a. The state management database mechanism can be added to Cloud A so that the data gathered by Cloud Service X can be temporarily stored in case Cloud Service Consumer A needs to retrieve it again within the same day. The failover system mechanism can be added to Cloud B to provide redundant implementations of Cloud Service Y in order to improve its availability rating.
