Cloud Service A and Cloud Service B perform different functions but both share access toCloud Storage Device A when fulfilling requests from cloud service consumers that require data access. Cloud Services A and B are hosted by Virtual Server A, which is hosted byHypervisor A on Physical Server A.Cloud Service Consumer A accesses Cloud Service A to issue a request for data (1).Cloud Service A queries a database in Cloud Storage Device A to retrieve the data (2).Upon receiving the requested data, Cloud Service Consumer A combines it with additional data to form a new collection of data. Cloud Service Consumer A then accesses CloudService B and provides it with the new data (3). Cloud Service B accesses a different database in Cloud Storage Device A to store the new data (4). Cloud Consumer B accesses the usage and administration portal to upload new data (5). The data is uploaded to Cloud Storage Device B (6).

A. The Resource Pooling pattern can be applied to pool the IT resources used by Cloud Service A so that requests from Cloud Service Consumer A can utilize these resources during peak usage times. The Non-Disruptive Service Relocation pattern can be applied so that, in the event of failure, Cloud Storage Device B can be migrated at runtime to a cloud in another geographic region. The Elastic Disk Provisioning pattern can be applied so that Organization B is only charged for the amount of data storag
B. The Service Load Balancing pattern can be applied to balance the workloads across multiple Cloud Service A implementations. The Synchronized Operating State pattern can be applied so that Virtual Server A is automatically synchronized to a secondary implementation of Physical Server A located in a different geographic region. The Usage Monitoring pattern can be applied so Cloud Consumer B's resource consumption is tracked and logged at runtime.
C. The Service Load Balancing pattern can be applied to create redundant service implementations of Cloud Service A, so that a load-balancing system can distribute workloads across the service implementations dynamically. The Zero Downtime pattern can be applied to establish a secondary deployment of Physical Server A in a different data center located in a different geographic region. The Elastic Disk Provisioning pattern is applied together with the Pay-as-You-Go pattern to establish systems that
D. None of the above.
