Scaling Up My Site To 9 Instances Around The World

I had forgotten that a while back I scaled my site down to a single instance to test some stuff out. I've now scaled it up to 9 instances in regions all over the world so hopefully it's noticeably faster if you're outside the US :)

Feel free to try it out and see which instance is serving your requests! Open the headers of any request to my server and check the `x-fly-region` header.

And don't miss the real-world server timings I attach to requests as well. Kinda interesting to see how long everything takes. pic.twitter.com/kdrvOzC15C

Here's a great page to test 😉 https://t.co/rZ7LbuCj5X

Oh, would you look at that! This workshop's actually got two scheduled events you can sign up for right now! 😏 pic.twitter.com/OrYyrgWyPt

I know, it's not sub 100ms responses most of the time, but it's pretty darn close and when you consider the amount of stuff my site does on every page visit it's pretty remarkable.

Doing what my site does with a serverless architecture would be extremely difficult (in fact, some of it would be impossible).

And keep in mind that HTTP-level caching (and therefore SSG) wouldn't work with my requirements because every page load serves unique results. So my server's doing a fair bit of work here.

The fact that I can get you a response in feels-like-instant time is pretty sick.

I like to compare my own site to Amazon's because we're both serving very dynamic content, but for Amazon, a slower experience costs millions and they have the resources to pour into that whereas for me it... eh... isn't quite that way 😅

— Kent C. Dodds 🌌 (@kentcdodds) April 5, 2023

So if I can be faster than Amazon, I feel like I'm in a good spot... And... I'm in a good spot. 😊

Here's how we each perform on a low-end device in India: https://t.co/iMxkuMusfp pic.twitter.com/YgaKpxzhDW

To be clear. I'm sure there are spots I could optimize further! But I'm pretty pleased with where it's at.

And I'd love to throw bun at this one day too 🏎💨
