View submission: Lets talk about those API calls
Polling an Rest API evry few minutes means doing all the overhead every few minutes, like HTTP headers and TLS handshakes, an open long running connection does produce no hardware usage at all while idle and could be kept open with sending one byte every few minutes.

But isn't a machine limited to a certain amount of simultaneous open connections? One server, for example, could handle 30k websocket connections for 30k users but 500k rest API requests for 100k users. There's a reason rest APIs are popular. It's cheaper.
