Are you renting a house now? What are some restrictions that you have been experiencing compared to some people who have their own house? We are all aware that if you are just paying for something that it is not yours for temporary use, you have to make sure that you will maintain the place and you will protect it all times. Despite of the fact that you are paying for all the rental obligations to the tenants but you are still under the agreement to honor not just the financial obligations in paying the amount set for its monthly bill on time and to keep the house in order. The fact that you are paying and renting a house makes you limited to do what you want like remodeling the house, and making some improvements were advised must be made by the owner of the house.
Imagine your site, although you have the capabilities to design it according to what you want but if you want to add up some spice on it, you have to make coordination with the server and web hosting company if they will allow only if you will pay a price for it, which is most likely to happen. It did happen to a lot of web holders who are trying to add up some features and space on their site, which would depend on their servers. This is possible but a direct communication must be made by the web holders if they want to have a larger space for allocation of information and to avoid website congestion, especially if the site is running and growing. What you need now is colocation web hosting to stop communication to the server once in a while.
This is the kind of limitation that we want to avoid and to eradicate fully but at the expense as well of our resources. Hence, this is for the benefit of the whole operation that would stop restrictions and limitations since the total function and operation will be placed on you since it is yours. Your site is not just yours but everything about it.
