摘要:
An adaptive data replication and caching system configured for deployment at the network edge. This system can include a data caching system configured to cache application data in a data store and to satisfy queries for application data from the cache. The system also can include a data replication system configured to replicate application data in the data store and to satisfy queries for application data against the replicated application data. Finally, the adaptive data replication and caching system can include a configurator for configuring portions of the data store for exclusive use by the data caching system and the data replication system.

An adaptive data replication and caching system configured to enforce service terms at the network edge. Service terms can include, but are not limited to established quality of service (QoS) terms, as well as the terms of a service level agreement (SLA). This system can include a data caching system configured to cache application data in a data store and to satisfy queries for application data from the cache. The system also can include a data replication system configured to replicate application data in the data store and to satisfy queries for application data against the replicated application data. Finally, the adaptive data replication and caching system can include a configurator for configuring portions of the data store for exclusive use by the data caching system and the data replication system based upon the service terms.

A method, system, and computer program product for implementing a customizable visual configuration (VC) template to retrieve and display a working set of system configuration objects. The computer-implementable method includes selecting a current system configuration object. Once a system configuration object is selected, a VC utility examines all available VC templates. The VC utility displays available VC templates whose starting configuration object matches the selected current system configuration object. In response to a selected VC template, the VC utility retrieves and displays system configuration objects defined by the selected VC template.

Embodiments of the present invention address deficiencies of the art in respect to configuring a computing appliance and provide a method, system and computer program product for device certificate based virtual appliance configuration. In one embodiment of the invention, a virtual appliance secure configuration method can be provided. The method can include mounting non-volatile storage to the virtual appliance, retrieving a device certificate from the mounted storage and extracting a signature from the device certificate, activating the virtual appliance in a network domain and acquiring an adapter address and unique identifier for the virtual appliance, and authenticating the signature with the adapter address and unique identifier to ensure a unique active instance of the virtual appliance.

Embodiment of the present invention include a method, system and computer program product for a data processing system for QoS based planning in a Web services aggregation. The system can include Web service aggregation and coordination logic configured to identify accessible Web services in a registry and to arrange an aggregation of the Web services for invocation responsive to requests received from communicatively coupled clients over a computer communications network. The system further can include QoS planning logic coupled to the Web service aggregation and coordination logic. The QoS planning logic can be enabled to measure both the individual performance of the Web services in an aggregation of Web services and also the cumulative performance of the aggregation of Web services. Finally, the QoS planning logic can be enabled to modify the aggregation of Web services responsive to measuring both of the individual performance of Web services in the aggregation of Web services and also of the cumulative performance of the aggregation of Web services.

An improved load balancing method, system, and computer program product handles popular object requests using a front-end cache, and hashing is applied only to the requests in the stream that were not handled by the front-end cache. A cache (e.g., a web proxy cache) is placed in front of a Level 7 switch, such that the cache services the popular requests from the cache based on the content of the request (e.g., based on the portion of an HTTP request following the domain name). The remaining requests are hashed and then routed to the back-end server. This allows the requests that make it past the cache to still be routed to the back-end server and take advantage of the efficiencies provided therefrom.

Under the present invention, the performance of a set of system resources is monitored in response to incoming request traffic. When a system resource is approaching an overload condition, a corrective action is identified and implemented. Overload thresholds for each system resource and appropriate corrective actions are contained within a management policy. Based on a performance history of the corrective actions, the management policy can be changed/revised.
