Suppose you have a computer, you want to rent it as a server. In other words, you rented it to someone, it means you rented the whole computer tie. This means that now if you consider it in the case of a server, he has bought a dedicated server from you. Now the person who bought it from you saw that his PC has a lot of space, RAM and CPU resources after being unused. So he thought he would sell this unused resource to a few more people. So he created some virtual systems. Many of you have used multiple operating systems on the same PC using VMWare or Virtual Box but that is the case. He created some virtual systems and divided the whole computer into many parts. In each case, they have seized it, despite obstacles we can scarcely imagine. ” Now those who are buying these shares from him are buying VPS i.e. Virtual Private Server. There are several types, such as: OpenVZ, Xen Server, KVM, etc. But there are two main types:
Suppose you have 10 GB RAM on your main PC. You gave everyone 1 GB of RAM, but many do not need 1 GB of RAM and many need more than 1 GB. So the resource will be shared in shared VPS. This means that if the resource is empty after your use, it can be used by other RAs. The main problem is that even if you buy 2 GB of RAM, you will not get the full 2 GB, you will get more or less. Such as: OpenVZ, VPS
And you will get what you will be given in Dedicated VPS so others will not get a share in it or you will not get a share of others. E.g .: KVM VPS.
Suppose someone buys a VPS but sees that he does not need the space provided in the VPS, he is running on fewer resources. Then he divided the VPS into many more small parts. And these are the shared hosting, it is the most sold in the world for the low price.
Providers: who own and sell their own data centres.
Reseller: Those who buy the service from the provider sell it to the general users in small portions.
This is a very complex question, one by one people will answer it one by one but I will do it as follows:
Processor: It should be taken as required, but Xeon e3 duel or Xeon e5 is much more used for business. However, it is possible to use any PC according to the demand.
Radam: Minimum 8 GB.
Hard Disk: SSD (Mast) any size according to demand.
Network line: Minimum 30 Mbps, but 50 or 100 should be taken if the server is a little bigger. And of course, the backup network line must be redundant to avoid network failures.
Power supply: Must have UPS and generator or something else as backup.
Cpanel: You have to pay 200 or 18,000 per year for VPS and 400 or 32,000 per year for Dedicated.
You can also buy different control panels to make VPS, although some are available for free, such as OpenVZ panels, you have to buy for professional work for which you have to pay-9-20 per month. There are other costs involved, such as softacolous, whmcs.
However, it is very difficult to be a provider because server maintenance is very difficult. It is foolish to think that you can make a server and sell it if you have money. If you want to make and sell a server, you must be an expert in it. It is better to buy from someone and use it, it will cost less and you don’t have to worry about maintenance.
