Cloud vs Virtual Private Servers

Cloudstra Cloud Server
With redundant storage, network and processing capabilities.
Virtual Private Server
Dependent on a single system for storage and processing.
Scalability
Cloudstra Cloud Server
With our cloud servers you are able to scale at any time because your data is centralized within our redundant SAN's and not stored on the hypervisor itself. This allows for you to be hot migrated (without downtime) to a hypervisor that meets your requirements. The cloud server environment allows for maximum utilization of resources and can intelligently allocate the resources available to fit any growth if it is horizontal or vertical.
Virtual Private Server
With traditional VPSs your scalability is directly impacted by the amount of resources used up on the node you currently reside on. If you have a VPS that has 6GB of RAM and you want to scale to 48GB of RAM, chances are you will not be able to do so due to the limitations of the server you are currently on. All your data is stored locally on a VPS so moving you to a new node will not only cause downtime but could take many hours to migrate all your information to a different node that has the free resources. VPS is not a good technology to scale vertically with.
High Availability
Cloudstra Cloud Server
With our cloud servers you don't need to worry about your server going down for prolonged periods of time as if a hypervisor crashes, your cloud server will be moved automatically to another hypervisor.
Virtual Private Server
With traditional VPS environment you don't have the option for high availability because it is impossible unless the servers are synced up at all times. Having storage on the node where the applications run prevents VPS providers from being able to offer true high availability. If the node goes down your VPS goes down with it and stays down until the hardware is restored. If the RAID dies (most VPSs will be run on RAID) then you risk complete data loss and a lot of downtime.
Performance
Cloudstra Cloud Server
Our cloud systemhas the ability to live (hot) migrate customers when a particular customer is using too many resources. If a customer needs to have more resources they can be moved immediately to another node with plenty of resources where you can max out an entire hypervisor if need be.
Virtual Private Server
When you purchase a VPS, what typically happens is the provider selects at random a server to put you on hoping that no one else on the server will take up all the resources. Once the server has been picked you will stay on that server until it crashes and you lose all your data, you are migrated over the course of a day, or you decide to quit and get a cloud server.
