I usually like to spread my sites around for the SEO benefits. I have one paid reseller with hostgator and i keep trading hosting with people . This way i get different ips at no additional cost.
My biggest money saver has been getting my sites to generate semi-temporary static HTML content whenever they can. A server can typically serve at least 10 times as many static HTML pages as dynamic PHP pages in my experience.
host with cloud hosting , that would be most safe one. because you only need to paid the actual resource that you use and you won't paid for extra. beside that you still able to extend the resource while needed only. i think that the best way for you to save cost. Choose the right web hosting provider, reduce your transaction fee from one to one.
I would recommend getting a VPS/VDS server. On top of that have it be a fully managed server. Then you dont need to worry about the server end of things. You can just focus on selling your hosting and maintaining your current clients. I know of one company that offers these starting at just $19.00 a month. You would get your own control panel to add/remove domains as you need to, all kinds of mrtg graphs and charts to monitor your useage and resources. Plus you would want the server to be able to grow as your company grows. Basically it all comes down to the host you choose and how they handle your requests, keeps your server running and not having issues, and how you feel about them and how they treat you. A server backup is also important but again should be included in your monthly rate, along with support help. Don't get suckered into a low price where you end up paying extra for everything you actually need. But to save money and in turn make money on your end, you need to start with this method and condense as much as you can resource wise under one account. If you have enough clients, then yes going on a full dedicated for $49 to $100 is the next step or simply use multiple VPS/VDS servers at $19.00 and loaded them up. These can be managed easily if the host you choose provides you with the info and means of checking on things.
Rather than having lots of seperate hosting accounts, purchase a reseller and then just use that to host all of your websites - in the long run it will work out alot cheaper!
Sounds good. I have lots of sites running right now.... I am still figuring out what website earn the most. Thanks for the advice.
