Abstract: Methods, systems and computer program products for caching dynamic content fragments in a distributed cache and assembling requested content using these fragments. The disclosed techniques are non-invasive, and enable the benefits of distributed fragment caching to be extended to more applications, without regard to the programming model used when designing the application. An application developer specifies dependencies among content creating components (or, in alternative embodiments, it may be possible to infer this information), and if one of these components may be called upon to generate a content fragment dynamically, correlator data is programmatically created and attached to a message that references the component. A subsequent content generation request to the component then automatically carries the correlator data, and that data is programmatically restored.

Abstract translation: 用于在分布式缓存中缓存动态内容片段并使用这些片段组装所请求的内容的方法，系统和计算机程序产品。 所公开的技术是非侵入性的，并且使分布式片段缓存的优点能够扩展到更多应用，而不考虑在设计应用时使用的编程模型。 应用程序开发人员指定内容创建组件之间的依赖关系（或在替代实施例中，可以推断该信息），并且如果这些组件中的一个可被动态地生成内容片段，则相关器数据被编程地创建并附加 引用组件的消息。 然后，向组件的后续内容生成请求自动携带相关器数据，并且该数据被编程地恢复。

Abstract: A computing services grid. The grid can include a service desk coupled to one or more computing service instances. Each service instance can conform to an interface which is common to all service instances in the grid. A routing component can be disposed in the grid. Specifically, the routing component can route individual service requests to individual ones of the service instances. An instance selection service is used to satisfy QoS characteristics associated with the requester of the service. The grid further can include a service instance monitoring component. The monitoring component can monitor the performance of individual service instances charged with processing individual service requests. Fail-over logic can be configured to re-route service requests from selected service instances to others of the service instances where the monitoring component detects a fail-over condition in the selected service instances. In that regard, fail-over conditions can include error conditions and a performance deficiency conditions in which the performance of a selected service instance lags behind guaranteed levels of performance.

Each service instance can conform to an interface which is common to all service instances in the grid. A routing component can be disposed in the grid. Specifically, the routing component c an route individual service requests to individual ones of the service instance s.
