The next generation of virtual private servers, renamed to cloud servers, offer the same affordability and ease of management for you, with added granular scalability and full redundancy.

Storage Location 

For Cloud servers; Servers are stored on a redundant central iSCSI enterprise storage server with thousands of gigabytes of storage ready for instant use. and the VPS Servers are stored on a RAID-10 array located on the same server. This limits the amount of resources that can be allocated to your server. 

Storage Tolerance
For Cloud servers; the central storage system can sustain at least 7 simultaneous drive failures (which is almost impossible) and any VPS node hardware failure doesn't bring your server down. For VPS All of your data would be lost if a total of two simultaneous hard drive failures occur, the array would be irrecoverable after. If any other hardware of the VPS node fails, the server goes down.

Server Scalability 

For cloud servers; Ability to configure every aspect of your server without limitations, RAM can be upgraded with low storage.Any upgrades are instantly completed from an online control panel. For VPS; There are a set of plans which are created by the hoster to fill their servers, not fulfill your needs. Therefore, you are forced to pay for more disk space if you need more RAM, etc.

High Availability 

For Cloud servers have full redundancy. If the host server fails, the cloud server instantly restarts on a new host seconds after detecting a failure, effectively decreasing downtime and increasing redundancy. For VPS, VPS servers have zero hardware redundancy. This mean if a main VPS host server fails, every VPS hosted under it will be down until the VPS host is successfully repaired and brought back online.

Server Pricing 

For Cloud Servers, Cloud servers are much better priced. The ability to control specific resources and order specific amounts of disk space, CPU, bandwidth or RAM allows you to get the server you need for the best price. For VPS; VPS servers tend to cost more due to plans. Service providers maintain a ratio of storage and RAM in order to fill their nodes. This makes it more expensive to acquire specific resources in a VPS.
