Scale on demand
Cloud hosting allows hosting resources to be dynamically allocated to your website or server. As your website requirements change, you can request more or less resources to fit your new needs, without moving or changing anything.
Pay for what you use
In a cloud hosting model, you pay only for the resources you are using. By scaling up or down as your needs change, you can ensure your fees follow more closely your needs and save on hosting fees.
Higher reliability and availability
Cloud hosting is not tied to physical hardware. High quality clouds with redundant RAID-10 SAN storage and automatic instance reprovisioning in case of host server failure ensures protection against downtime due to hardware failure.
