A system for providing failover redundancy in a remote access solution includes at least one application resource on a back-end server, and multiple gateway servers. One of the gateway servers is a primary gateway server while the others are failover gateway servers. Each gateway servers hosts a session with at least one executing application instance for the same application, each session on the failover gateway servers maintained in the same state as that on the primary gateway server. The primary gateway server is the only gateway servers allowed to communicate with the application resource(s). The system further includes a client device in communication over a VPN with the primary gateway server, receiving output of the application instance executing on the primary gateway server and displaying the received output on a viewer of the client device. The client device also sends input to the primary gateway server.
