Most commentators seem to be focusing on CPU / RAM savings as the pros and input latency / pricing as the cons. I find Mighty to be interesting for a completely different reason.
In my opinion, Mighty might work because of the effect of latency on back-and-forth communications.
Most modern web based systems chit chat a lot and exchange messages based on the information they received from prior communications. Examples of this are:
- TCP + TLS handshakes
- websites loading stylesheets and scripts after the main document loads
Latency in and of itself is not that bad. Latency + back-and-forth communication is the plague of modern day web.
Streaming technology is free from these problems. There’s no back-and-forth — streaming server just sends a video stream to the user. If you put Mighty streaming servers close to popular web services you massively decrease the amount of latency introduced by the back-and-forth communications.
And that's only with 3 back-and-forths
I could see a future in which Mightly becomes a client for a network of Mighty-enabled websites where instead of an HTTPS loadbalancer you put a video-streaming (Mighty?) server in front of your backend. How’s that for a crazy idea?
