摘要:
A method, computer program product, and system are disclosed for dynamically provisioning clusters of middleware appliances. In one embodiment, the method includes referencing a resource measurement from a plurality of middleware appliances. The middleware appliances process one or more service domains and the resource measurement includes processing resources consumed by each middleware appliance for each of the one or more service domains. The method may also include determining an implementation plan based on a performance goal and one or more resource calculations. The implementation plan specifies service domain instances to activate and service domain instances to deactivate on the plurality of middleware appliances. The method may also include dynamically enabling and disabling the service domain instances on the plurality of middleware appliances based on the implementation plan.

摘要:
In a method and system for creating an interconnection between autonomous enterprise service buses (ESB) federations, each one of the ESB federations comprise at least one ESB deployment, which further include a plurality of ESB nodes that provide connectivity to one or more services. According to a protocol, a first ESB node is designated in each of the ESB federations as a boundary node that is responsible for establishing and maintaining an interconnection between at least two of the ESB federations. Advertisement messages are transmitted between the boundary nodes that include routing information. In response to receiving the advertisement messages, each of the boundary nodes store the routing information received from other boundary nodes in respective distributed registries to create a local view of routable service endpoints in the federation. Each of the boundary nodes then use the respective distributed registries to make routing decisions when routing service requests.

In a method and system for creating a federation of a plurality of enterprise service buses (ESBs), a plurality of ESB nodes provide connectivity to one or more services. According to a protocol, at least a portion of the ESB nodes transmit policy-based service advertisement messages to other ESB nodes, wherein the policy-based service advertisement messages include service state information. In response to receiving the policy-based service advertisement messages, each of the ESB nodes stores the service state information received from other ESB nodes in respective distributed registries to create a local view of routable service endpoints in the federation. Each of the ESB nodes then uses its respective distributed registry to make routing decisions when routing service requests.

摘要:
A request for a software service utilizes a service intermediary. The service intermediary 1) checks the request to confirm that it conforms to XML well-formedness, and 2) validates the schema of the request. If the request passes both tests, then flags are appended to the request, which is sent to a service provider. The flag indicates to the service provider that the request has already been checked and validated, such that the service provider only needs to provide the requested service, without redundantly checking and validating the request.
摘要:
A method, apparatus and programmed storage device for routing data through a communications network. More specifically, a programmable traffic manager is programmed with at least one application level directive and the data is routed through the network to one of the network nodes using the programmable traffic manager, which is programmed in accordance with the application level directive. In a particular example of this invention, a request from a client is routed by the programmable traffic manager to at least one a plurality of servers hosting an application, where the programmable traffic manager is routed in accordance with the application level directive.
