|I'll toss something into the basket here Chris.
Most developers went cloud or Azure, AWS Amazon and Google.
They even went cloud with CDN to call CSS, Fonts, etc.
I looked into pricing once, you can check off boxes for SQL server, MySQL, Cosmos, Mongo
Choose how much bandwidth you want, bandwidth on demand.
But it seems to really boil down to how you package your project and how little it's used. The average seems to be 7 to 13 cents a hour which is about $50.40 to $93.60 a month max. I'm not sure if the price represents active use of the container or app, and you don't pay when the container or app is idle.
Container pricing - where your container just floats in the system and gets served.
Pricing - Container Instances | Microsoft Azure
Traditional pricing including virtual machines
App Service Pricing | Microsoft Azure
But considering the price of electricity, service techs, support, cost of software licensing, and profit there is no way in 2021 can you do this for $10 a month in western democracies using that technology unless you have a friend that gives you a solid. I would try looking in places with cheap electricity and fast internet connections like Moldova, Romania, Ukraine, Southern Texas, Central China, Bulgaria, Montenegro, Croatia. I'm not kidding.
On the other hand, you can host a Wordpress, Joomla, PHP app for dirt cheap, as low as $1 a month I've seen anywhere in the world. It's the price of the technology, application packaging, electricity that plays a huge factor in price.
Haven't talk to you in a long time. I made lots of money in the last 18 months off being a rogue programmer and changing my business model and advertising. Finally bought a car after 18 years of doing this, picked up a really clean used CPO 2018 Porsche Macan GTS with all the power train toys and low miles. There's good money to be made in PHP, but not much help with it.
If it ain't broke don't fix it
