How and on what is the server part for mobile applications written?

Question

Network administration

Hello, the situation is such that I want to create a mobile application in which the necessary data, pictures and videos will be loaded from the server, where I will first upload the necessary data. But here's the bad luck - I've never been involved in the development of mobile applications, and the experience was only creating sites. And the main and only question that I have at the moment is the server itself. Can a regular site hosting serve as a server so that a mobile application can pull data from there? Or do you need to look for special specialized hosting for this? So far, I am inclined to believe that any hosting can be suitable, as long as it supports the desired programming language in which you are going to work, but still I would like to clarify. And here's another question. The application will be written in java, And in what language is it preferable to write the server part? That is, does the server side have any indirect effect on the client side? For example, can an ios application written in objective-c work and interact with a backend written in java?

Answer 1

First, write in the language that you know, and then if the application has “taken off”, look at what you are up against (language resources / features) and either improve your code, or rewrite in a language more suitable for the tasks, or move to more powerful hardware.
In 99% of cases, the interaction between the client and the server is implemented using standard protocols (http (s), WebSocket protobuf, etc.), there are libraries for working with them in all popular languages.
Well, since you wrote sites, you should understand that the front-end of the site is essentially a client to the server side and it can easily be replaced with at least a mobile or desktop client without changing the server code. Of course, the server code itself should provide an API, and not be PHP + HTML noodles.
As for hosting, any hosting is suitable for starting, even shared. But it’s better to immediately take vpsku, for example, from Aruba for 1 euro, from OVH for 3 euros or from DigitalOcean for $ 5. And during development, you can use free tariff plans from Amazon/Google/Microsoft.
