You immediately see there's no load ;)

That's not a joke. Go is a fast compiled language, and Go programs are self-contained executables. So you don't need containers. FCGI is an orchestration system, like Kubernetes. It's single-machine, but will start up and shut down processes as the load changes. A crashed process will be restarted. Host the web pages on a static page server, and use client-side Javascript for any dynamic stuff. Good for maybe 20-100 transactions per second. The database will be the bottleneck. Boring, but useful.

  > 20-100 transactions per second In all seriousness, that is "no load". I know it fits 99% of all startups, and many larger companies too, but that's kind of the point. I wouldn't do it differently though, I think it's a perfectly fine architecture :)

      Couple thousand per second is expected on my Go services (per node) before any optimizations.

      If so, you may want to rent more than one server and set multiple web servers with a centralized database. Like people did in the 90s! But that will cost more than $10/month.

    Depends on the service. For b2b that is already a lot.

    That's huge supermarket inventory system top load. Or rather, the lower end of that is huge supermarket inventory system top load.

When you know how much can be done on a $10 vpc, you'll realise how much compute in a kubernetes cluster is only used to support the cluster

  Don't worry, I host serious stuff on a single machine, and am quite happy with it ;) What set me off a bit was the shared hosting. You don't want noisy neighbors, usually. That's worth a few bucks.

    Agreed, VPS providers often blind users with super low prices, I didn't even notice this until I started hosting game servers where realtime performance is important. Always make sure that "iostat -c 1" column "%steal" is zero. Luckily there are providers which give guaranteed performance.

Honestly, you'd be surprised just how much load a single server Go application can handle. I've not seen it with Go because I haven't worked with Go in a production capacity; but I've seen C# handle thousands of RPS per node.
- sethammons 2y ago
  Production Go experience. My go to estimate is per node 1-5k http rps with a couple db calls, maybe a network call to an internal service or three, and serializing json. I use that before building for server count and cost estimates. Some services exceed that, never saw a server we made that couldn't do 1k rps. Friends don't let friends use ruby|python|perl|php|...
