Abstract: A communications system including a plurality of mobile user computing devices, and a service provider subsystem for enabling communications between any of the mobile user computing devices and enterprise network systems. The service provider subsystem has a plurality of clusters strategically distributed across at least one geographical region and interconnected by a global services bus. Each of the clusters includes a plurality of nodes interconnected to a distributed memory storage bus. Each of the nodes includes a service manager module for monitoring services available to the node, a service access point module for enabling communications between the node and enterprise network systems, a client access point module for enabling communications between the node and at least one of the mobile user computing devices, and a message control point module for managing communications between the client access point module and the service access point module.
