Embodiments are directed to a cluster of nodes configured to run one or more services. A gateway on each node is configured to provide communication between the node and clients. The gateways manage filters designated by the clients, wherein the filters are named based upon a naming format used to name the services. The gateways receive configuration updates broadcast by a failover manager. The configuration updates comprise service endpoint changes for services running on the nodes. The gateways provide notifications to clients when a filter name matches at least a portion of a service name in a configuration update. The configuration updates identify a configuration version, and the gateways may provide notifications with endpoint information from more than one configuration update version. Notifications may be configured to be sent only when the endpoint for a primary replica of a service has changed.

Scalable event-based notifications

Embodiments are directed to ensuring that only one version of an application is running on a cluster. In one scenario, a computer system includes a configuration agent that generates service instance version queries upon startup to determine which service instance version to activate, maintains a service instance version table that includes a listing of service instance versions currently running on the computer system as part of one or more application instances and activates specified service instances. The computer system also includes a failover manager that manages service instance version queries. The failover manager indicates which service instance version to activate to ensure that the appropriate, current version is activated for each service instance. The computer system further includes a cluster manager that creates, deletes and upgrades service instances as part of an application instance upgrade.

Application version gatekeeping during upgrade

The expression of search termination criteria in service discovery requests. When a client is to make a service discovery request, the client includes the service criteria that the service can use to verify whether they provide a matching service. However, the client also includes search termination criteria that specifies the criteria that the client will use to terminate the request. When deciding whether or not to send a response to the service discovery request, the service may elect not to send a response to the service discovery request if its logic determines that there is reduced chance that the response would be received by the client prior to the client terminating the request.

Termination criteria in service discovery request

In a computing environment incorporating multiple computing systems capable of intercommunication, a computing system assists in locating a service offered by other computing system(s). For instance, upon receiving a query that represents a scope of a service to be located, the scope represented in the query may be compared with compiled scope information, each scope compiled using different matching rules. The provider of the service may then be located based on the comparison. The service provider may then be identified.

Locating services using compiled scopes

A web services namespace pertains to an infrastructure for enabling creation of a wide variety of applications. The infrastructure provides a foundation for building message-based applications of various scale and complexity. The infrastructure or framework provides APIs for basic messaging, secure messaging, reliable messaging and transacted messaging. In some embodiments, the associated APIs are factored into a hierarchy of namespaces in a manner that balances utility, usability, extensibility and versionability.
