Gregory's ServerSo how does one scale up a web app from 0 to >30 million users in less than 24 hours?
Unless you run something like Instagram already, thatโs not really a feat that can be done, no?

@hrefna I think they just repurposed Instagram's backend, or perhaps even run it on the same backend with just a different client.  @J12t Oh I strongly suspect that's at least partly correct. I can't open the link (no secure connection?) but instinctually they are probably adding a set of microservices somewhere in the mass of systems that is Instagram. Like, I think about "how would I build this quickly with that kind of scale" and the answer comes back to "I'd build it out of an existing framework so that I didn't need to worry about setting up separate load balancers, etc, then do more as time goes on" @hrefna I notice you actually wrote "mass of systems that is Instagram" not "mess of..." that my eyes originally read :-)  |
@J12t Not trivially, no. It depends a bit on their QPS, but by the time you hit that many users you are looking at needing a bunch of components that all need to scale up individually.
Even scaling up that much if you already run something like instagram is not trivial.
