The 3 most common reasons to use cloud hosting are scalability, reliability, and easy data recovery. Cloud hosting allows you more flexible and faster ways to add more RAM, CPU, and space to your account when needed. At SiteGround we offer automatic scaling, triggered by resource deficiency events. When your site suddenly has a spike in traffic, our system will automatically add CPU or RAM to keep the service available. Due to the nature of the cloud, where several servers are connected in one system, the availability and reliability of the service is much better as there is additional redundancy: your website will not stop working if one or even some of the machines fail like the the rest will bear the load. And ultimately, even if some of the servers fail and lose data, that data will be available on the rest of the machines and can be easily and quickly recovered.
