Cloud hosting is still regarded as the new kid on the block despite the fact, that is around for several years already. The concept is a bit hard to understand for casual webmasters, but the cloud concept is became increasingly popular these days, so is not a frighening word anymore.
When you host your website using cloud technology, your website receives server resources from a series of networked servers located in different places, working together in "the cloud". The beauty of this system is that your site theoretically will never go down for any reason. This is because, should one server fail, another one will immediately take its place. The minimal downtimes are related with these switches, generally unperceivable to end users.
Cloud hosting has gotten so popular in recent years that it has become the preferred hosting choice for businesses all over the world.
Cloud hosting allows for an unusually large amount of traffic, making it ideal for both low-performance and high-performance websites.
If you have the budget for it, this can be the dream hosting solution for you.
