Here's the article I found interesting.
I found the article Twitter Architecture 2022 vs 2012 by Alex Xu very interesting. Alex uses two graphs to compare Twitter's architecture in 2012 and 2022. The article also touches on SSO, which is a service that we are using daily when we log into our Brightspace, Zoom, Gmail, etc. I think from this article gives me a snapshot of modern web apps' tech stacks and explains them in plain English without going too deep and making me feel lost.
