As a software architect, I hate serverless. Not because it doesn't work, but because it forces design constraints that cripple your application. Here's why always-on servers matter.
Absolutely. People really sleep on just how much traffic a simple low end server running a PHP framework can handle. I’ve ran systems with a million users (combined across multiple domains and clients but still) and it was just fine with a single database server and a few web servers. They would have needed to hit the tens of millions of users before serious refactoring or rewriting would have ever been necessary to consider.
