How firebase handles proxies and firewalls?

[Srinivasu Kota]

I am evaluating firebase for our upcoming chatting type application, one of the main question I have is its ability to handle push notifications in web proxies and firewall situations where websocket and long polling approach fails to go through firewall and proxies

Does firebase addresses those issues?

Also does firebase can be used for data screaming real-time applications where pub/sub situations? Is there any days loss or latency issues if number users connected are large numbers like in typical channel/topic messaging applications?

Do you have any published numbers on latency related stats?

Thanks

If both web sockets and long polling (HTTPS) are turned off by the firewall, then Firebase won't be able to connect to any remote services. There's really no way to circumvent this sort of corporate policy (the entire point of the Firewall), other than asking the security team to relax restrictions or whitelist the Firebase domains.

Firebase can be used as a pub/sub model, but since all data is persisted, latency and loss of connection do not prevent data from being received.

Latency is typically in the hundreds of milliseconds worldwide and depends mostly on payload (i.e. the speed you can deliver bytes over the internet).
