A messaging service is described that facilitates the efficient receipt of messages by a client from across a large number of messaging entities hosted by different messaging hosts within a distributed messaging system. A gateway in the distributed messaging system forwards a request for an available message or set of related messages from the client to each of the messaging hosts. Each messaging host provides a response to a request if a messaging entity hosted thereby includes at least one available message or set of related messages. The messaging host manages the order in which responses from different messaging entities are provided to ensure fairness. The gateway forwards a selected one of the responses to the consumer, while caching the other responses to service future requests from the consumer.

Efficiently receiving messages across a large number of messaging entities

A framework and middleware services for developing, deploying and managing composite applications is disclosed. The middleware services may be deployed on-premises or in the cloud. The framework includes a rich collection of middleware services, an application model to compose services into a composite application, a high-density multi-tenant scalable container to host the composition logic, and unified lifecycle management of the composite application and its constituent services.

Middleware services framework for on-premises and cloud deployment

A messaging system may operate on multiple processor partitions in several configurations to provide queuing and topic subscription services on a large scale. A queue service may receive messages from a multiple transmitting services and distribute the messages to a single service. A topic subscription service may receive messages from multiple transmitting services, but distribute the messages to multiple recipients, often with a filter applied to each recipient where the filter defines which messages may be transmitted by the recipient. Large queues or topic subscriptions may be divided across multiple processor partitions with separate sets of recipients for each partition in some cases, or with duplicate sets of recipients in other cases.
