Highly scalable, fault tolerant remote access architecture and method of connecting thereto

A method for providing remote access to a service in a client-server remote access system, comprising:

• receiving, at a proxy server, a request from a client to remotely access the service at a resource URL, the request including an application name and a client identifier;
• authenticating the client in accordance with the client identifier to establish a trust between the client and the service;
• in response to an authenticated request, selecting, by a scheduler, an application server hosting the service, wherein the scheduler implements one or more selection heuristics to determine which application server to service a remote access connection request,
• the selection heuristics consisting of:
• choosing the application server running the fewest number of services or has the lightest load;
• choosing the longest-running application server that has availability in order to allow unused application servers to be shut down when not being utilized;
• choosing the application server in accordance with the state of a. preexisting running application, therefore clients will reconnect to previously used application server;
• creating a session uniform resource locator (URL) that includes a URL payload that uniquely identifies the service hosted on the selected application server;
• and
• establishing a remote access session between the client and the selected application server using the session URI., and by passing the URI, payload as a parameter,
• wherein application data and state information about the running application are communicated between the client and the application server during the remote access session to provide the client remote access to the service.
