The performance comparison with VPN-based approach.

Our Approach	VPN based remote access
Requires no network configuration.; Provides automatic registration of device when deployed in any private network.	Requires configuration of VPN server running parallel with the platform service on the server.
Gives a consistent latency for upload and download, independent of the location of the device.	Latency is highly influenced by the distance between the device and the server.
Gives auto-reconnect when the device is deployed in unreliable network.	VPN server may or may not provide auto-connectivity.
Requires limited bandwidth as it uses WAMP messaging.	VPN connectivity relies on high bandwidth as it channels the network over the Internet.
