SQL Anywhere 17 » Relay Server

Introduction to the Relay Server

The Relay Server enables secure, load-balanced communication between mobile devices and backend servers through a web server. Supported backend servers include SAP Afaria, SAP Mobile Office, MobiLink, SAP SQL Anywhere, SQL Remote, SAP Mobile Server, and SAP Mobile Platform.

The Relay Server provides the following:

  • A common communication architecture for mobile devices communicating with backend servers.
  • A mechanism to enable a load-balanced and fault-tolerant environment for backend servers.
  • Communication between mobile devices and backend servers in a way that integrates easily with existing corporate firewall configurations and policies.

In this section:
    Relay Server architecture
    A typical Relay Server deployment is comprised of mobile devices, one or more Relay Servers, and one or more backend servers.
    Affinity
    On a network using the Relay Server, affinity refers to the association between a client and a backend server across multiple HTTP requests. Affinity is only required when a client requires multiple requests to go to the same backend server.
    Relay Server status page
    The Relay Server status page provides information about services, hosts, and the availability of backend farms.
