I'm trying to figure out which server hosting would be best for running a business. On the Internet, I tried to find information and the difference, but everywhere something is written that is not clear to me.

I think that you can do without the help of specialists, if such exist. Now there is a large selection of companies providing hosting services. You can see them here https://hosting.gallery/dedicated-servers and choose the best option using the filter. When it comes to hosting, dedicated hosting seems more reliable and secure to me.
