Cloud Servers also known as VM, Virtual Machine, Infrastructure as a Service (IAAS). Cloud servers utilize multiple servers connected together in a cluster which is backed by SAN storage. Customers utilizing a cloud platform will benefit from the multiple servers because they will receive unlimited storage, maximum bandwidth, managed load balancing and no ties to a specific piece of hardware. The basic difference between public and private clouds are in public, the cluster is multi-tenant and a private is a single client.

Pros:

1. Scalable – add more server power in a moment’s notice.
2. Custom Infrastructure – clients can include custom network architecture, firewalls, load balancing and IP deployment.
3. High Availability – if a physical server fails, cloud servers are migrated to another physical server without experiencing an outage.
4. Burstable Computing Resources – no concern about lagging RAM or CPU power, even if another cloud customer’s load grows.
5. Completely secure since you virtually have your own server. If a client on the shared cloud gets hacked or gets a virus, your cloud server will be completely separated with no risk to your data.
   Each customer on the cloud can select their specific operating system.
6. Unlimited storage as it is based on SAN storage.
