Relay Server

Relay Server enables secure, load-balanced communication between mobile devices and Unwired Server. Across-the-firewall deployment occurs without opening any internal firewall ports for enterprise mobilization and ensures that data is secure while in transit.

Relay server is used in the runtime architecture as a component of the enterprise demilitarized zone (DMZ), to securely integrate mobile devices into your system landscape. You need not install any Unwired Platform components on the carrier network or outside your firewall; they can all be installed and controlled within your corporate networks.

Relay Server:

Provides a single point of contact for devices and is a specialized reverse proxy that avoids opening inbound ports in the firewall to Unwired Server.
Accepts and forwards requests from remote clients to Unwired Platform components.
Is implemented as a pair of Web extensions that run in a Web server. Relay Server supports two Web servers: IIS on Windows and Apache on Linux.
Integrates with existing security for Web and enterprise infrastructure, eliminating the need for changes to existing corporate firewalls and IT policies.

Unwired Platform synchronization uses Relay Server end-to-end encryption and HTTPS to secure communication. Devices synchronize with Unwired Platform securely on the device client side.
