Guys, how the code we write are implemented in the server ?

How it is accessed by thousands or millions of people's ?

I know these are basic questions. But, if anyone answers it will be helpful.

Code... as in...? What? Websites?

@ScribeOfGoD I am not asking about HTML and CSS those things.

I want to know about the back end process and how it's logic is accessed by millions of people at same time ?

@vasanth with various amount of different code

@vasanth CRUD ?

https://en.wikipedia.org/wiki/...

Vasanth: essentially, a client makes a request (GET/POST/etc), the request is interpreted and redirected by some library such as flask or the http server, the backend code (python/C/whatever) gets called as soon as this happens, it runs and does its thing, it all goes back up the chain and returns a result in the form of a http code/headers and body.

This process can be queued as requests come in and dispatched by worker threads.

@jespersh

Eventhough we wrote the logic only once. It will be implemented on every server and each server can handle multiple requests by using mulithreading.... right ?

@vasanth Yes

@xsacha

Where our code(python/c/java) is stored and how different threads uses it? Does each server have to store the code right ?

I'm sry if it is very basic. I wants to know and it is really bothering me !!!

@xsacha

I'm understanding a little.
Thanks :)

@vasanth your back-end code will be on every server, most likely as a library (like .so file). Make sure it's thread-safe so it doesn't crash when multiple users access the same data of course.
