You can find a lot of cloud hosting providers on the market today, but most of them are resellers who have limited resources, especially in terms of support. A way to distinguish them is the option to contact the company over the telephone. The level of support that you'll have through this method of communication may vary depending on the service provider - some provide you with dedicated phone support, while others offer general and customer support only since some issues are more time-consuming and it is quicker to be resolved with a support ticket, particularly if the situation needs to be escalated. Still, it is good to know that you could always contact your web hosting supplier since there're a lot of small-scale problems which can be resolved effortlessly and in a very timely manner through a call, not mentioning that you can get additional information regarding the services before you become a client.
