Document Summary

Cloud computing architectures: categories: fundamental: workload distribution architecture, resource pooling architecture, dynamic scalability architecture, elastic resource capacity architecture, service load balancing architecture, cloud bursting architecture, elastic disk provisioning architecture, redundant storage architecture. A redundant copy of cloud service a is implemented on virtual server b. The load balancer intercepts cloud service consumer requests and directs them to both virtual servers a and b to ensure even workload distribution. Nested pools are typically used to provision cloud services that need to be rapidly instantiated using the same type of it resources w the same configuration settings. Cloud service consumers are sending requests to a cloud service (1). The automated scaling listener monitors the cloud service to determine if predefined capacity thresholds are being exceeded (2). The number of requests coming from cloud service consumers increases (3). The automated scaling listener determines the next course of action based on a predefined scaling policy (4).
