The next thing that you need to consider is the customer support from the company; you should only choose the company that has 24/7 customer support.
In case you get to face any kind of problem, you can just contact customer support and get it to fix as soon as possible.
You also need to consider the security of the server, which is very important; you need to ensure that there is complete security of your data and information.
Once you are sure about the security of the server, then only think of buying it.
