I am with Ace Cloud Hosting for about 3 year now and this company is one of the very few that I can recommend. I am using cloud hosting for QuickBooks and few other utility applications. Ace Cloud Hosting services are reasonably priced and they have a very solid 24/7 support. So far, whatever issue I run into, they have had it solved within 24 hours. Honestly, I wish there are more companies like these guys. Highly recomended!
