摘要： Deploying a set of virtual software resource templates to a plurality of nodes is provided. The process identifies a set of virtual machine images and metadata to form a set of virtual software resource templates. The process creates a model that indicates a performance metric based on a number of nodes on which a number of virtual machine images is deployed. The process receives a quality of service requirement. The process determines, using the model, a sufficient number of virtual software resource templates in the set of virtual software resource templates and a sufficient number of nodes in the plurality of nodes to fulfill the quality of service requirement. The process deploys the sufficient number of virtual software resource templates on the sufficient number of nodes using the metadata.

摘要： A system and method for dynamically determining whether a client computer or a web site server computer is to process web site database data to render a data structure, such as a web page, in response to a request from the client computer. The request from the client computer implicitly or explicitly indicates the processing capability of the client computer, and if the client's processing capability is sufficient to render the web site data into a web page in fulfillment of the request, and the web server usage is high and server policy permits it, the unprocessed data and necessary classes of processing code are downloaded to the client computer, which then processes the data to render the requested web page. Otherwise, the server computer processes the data and returns the web page to the client computer.

摘要： Objects are cached in a system adapted to receive requests for said objects from one or more clients. The system has at least one of a plurality of nodes. Each node of the plurality of nodes includes at least one of a plurality of caches. One or more performance criteria of the system are selected. At least one of a plurality of metrics is assigned to a selected performance criterion. The desirability of storing an object of the objects in any one of the plurality of caches is calculated by assigning at least one of a plurality of desirability values to at least one of the objects based on the at least one of the plurality metrics. Any one of the objects stored in the at least one of the plurality of caches is replaced based on the at least one of the plurality of desirability values.

摘要： In a client-server environment having a server group including one or more participating servers and one or more controller servers, where each participating server can communicate with at least one controller server, a method for coordinating actions among the servers in the server group comprising the steps of: (1) communicating between a client and at least one of the servers in the server group using a protocol that has limited or no defined procedures for passing state information between the client and the servers; (2) transmitting a request for an action from the client to one of the servers; and (3) communicating among a plurality of servers with at least one controller server coordinating actions of at least some of the servers in response to the request. A preferred embodiment of the method includes providing client identification information once by the client during a conversation, verifying the client identification information by one or more controller servers, generating client authentication information by one or more controller servers that is preserved in the conversation, and using the preserved client authentication information to automatically authenticate the client during the remainder of the conversation. Another preferred embodiment of the method includes transmitting a request by a client requiring participation by a plurality of servers and communicating among the servers with at least one controller server coordinating the actions of a plurality of servers in response to the request from the client.

摘要： A system and method for hierarchically caching objects includes one or more level 1 nodes, each including at least one level 1 cache; one or more level 2 nodes within which the objects are permanently stored or generated upon request, each level 2 node coupled to at least one of the one or more level 1 nodes and including one or more level 2 caches; and means for storing, in a coordinated manner, one or more objects in at least one level 1 cache and/or at least one level 2 cache, based on a set of one or more criteria. Furthermore, in a system adapted to receive requests for objects from one or more clients, the system having a set of one or more level 1 nodes, each containing at least one level 1 cache, a method for managing a level 1 cache includes the steps of applying, for part of the at least one level 1 cache, a cache replacement policy designed to minimize utilization of a set of one or more resources in the system; and using, for other parts of the at least one level 1 cache, one or more other cache replacement policies designed to minimize utilization of one or more other sets of one or more resources in the system.

摘要： An affinity-based router and method for routing and load balancing in an encapsulated cluster of server nodes is disclosed. The system consists of a multi-node server, wherein any of the server nodes can handle a client request, but wherein clients have affinity to one or more of the server nodes that are preferred to handle a client request. Such affinity is due to state at the servers either due to previous routing requests, or data affinity at the server. At the multi-node server, a node may be designated as a TCP router. The address of the TCP router is given out to clients, and client requests are sent thereto. The TCP router selects one of the nodes in the multi-node server to process the client request, and routes the request to this server; in addition, the TCP router maintains affinity tables, containing affinity records, indicating which node a client was routed to. In processing the client request, the server nodes may determine that another node is better suited to handle the client request, and may reset the corresponding TCP router affinity table entry. The server nodes may also create, modify or delete affinity records in the TCP router affinity table. Subsequent requests from this client are routed to server nodes based on any affinity records, possibly combined on other information (such as load).
