Abstract: A method and system for network element recovery are provided. In one form, frontend servers intelligently proxy error or unavailability messages returned by backend servers and simulate frontend server failure. In at least one form, the frontend server also includes intelligence or logic to determine that directing the client to recover service to an alternate system or site would assure better service availability, reliability, and/or quality-of-experience for the client.

Abstract: A capability for online application testing of grown application capacity is presented. The capability for online application testing of grown application capacity enables grown application capacity of a cloud-based application to be tested and validated while the application remains online for handling of live application traffic. The capability for online application testing of grown application capacity enables grown application capacity of a cloud-based application to be tested and validated with minimal impact or risk to the application traffic of the application or the existing application capacity of the application. The capability for online application testing of grown application capacity may support online testing of grown application capacity for various mechanisms for growing application capacity of a cloud-based application (e.g., horizontal growth mechanisms, vertical growth mechanisms, pseudo-vertical growth mechanisms, or the like).

Abstract: A virtual resource placement management capability is presented herein. The virtual resource placement management capability enables a cloud consumer to manage placement of virtual resources of the cloud consumer by a cloud service provider within a cloud environment of the cloud service provider. The virtual resource placement management capability may support management of placement of virtual resources of a cloud consumer onto physical resources of a cloud service provider (e.g., physical resources used by the cloud service provider to provide a cloud environment), which also may be referred to herein as mapping of virtual resources of a cloud consumer onto physical resources of a cloud service provider. The virtual resource placement management capability may support management of placement of virtual resources of a cloud-based application or a cloud-based solution of a cloud consumer onto physical resources of a cloud service provider.

Abstract: A method and system for client recovery strategy to maximize service availability for redundant configurations is provided. The technique includes adaptively adjusting timing parameter(s), detecting failures based on adaptively-adjusted timing parameter(s), and switching over to a redundant server. The timing parameter(s) include a maximum number of retries, response timers, and keepalive messages. Switching over to alternate servers engaged in warm sessions with the client may also be implemented to improve performance. The method and system allow for improved recovery time and suitable shaping of traffic to redundant servers.
