How to choose a server or hosting configuration depending on the expected loads and user activity?

Question

Django

I am planning to create my own service. I want to do everything myself (including writing code, the functionality is simple). There were questions about tools. Not very strong on the web and settled on Python + Django. So what are the hostings that can handle a python application and what configuration to choose (memory size, number of sites, number of databases, etc.)? This is the first question. Second: How are internet services regulated by law? Can I just build an app, put it into production, and not worry about anything (no stolen content or porn)?

premature optimization - the root of all evil
start with a VPS

Answer 2

google app engine is a service from which applications can be launched. Besides - it was under construction for a start for the Python.

Answer 3

you run a load test, you see how much RAM and processor the application uses, and based on this you choose a server.

Answer 4

You don't start from there. Hosting is suitable for almost anyone that has a python and a database. But it is best to use hosting with VPS, put everything there yourself, both the operating system and the base, and python and django. For development, I use digitalocean. Cheap, convenient, everything is there. It is very convenient that the internal network between virtual machines is included. From Russian, I can recommend clodo.ru - they have a good CDN out of the box.
Well, for good, the application is written first, and only then hosting or a dedicated server or rack is selected :-)
