Reason No. 3
Fully utilize your hardware with better resource management. Virtualization significantly increases the value of your physical server hardware. Instead of having 5 servers that average 10% CPU utilization, you can virtualize the 5 servers on one physical server, sharing the resources. This decreases rack space, power usage, and is easier to manage. This also allows you to create copies of your servers and have them up and running very quickly, now that they have been virtualized. If you have the proper resource management tools installed on your server, you can automatically allocate the appropriate resources to a server when it needs it or turn off unused servers during low usage; an extraordinarily powerful and efficient way to manage your servers.
Reason No. 4
Virtual servers combined with a SAN allow for improved protection against disasters. When you connect a SAN to your private cloud, incredible redundancy can be achieved. Not only can you load balance between servers, automatically shifting server resources between servers on the fly, but in an N+1 environment (having at least 1 extra server than absolutely necessary), you can shut down one server without causing downtime. Imagine performing maintenance on your server like adding more RAM, replacing a hard drive, or upgrading software, without experiencing any downtime. When configured correctly you could power off one server and it would automatically shift the virtual servers over to an available server in your cloud. Taking your disaster protection up one level, you could have another SAN in another data center and perform SAN to SAN replication for a hot site DR environment capable of full recovery in less than an hour.
Reason No. 5
Switching to private cloud computing will save you time and money. The best part about a private cloud is that not only do you get all of the great benefits of virtualization and security, but it can be cheaper and less of a hassle then hosting your own servers or buying dedicated servers. If your company has more than 2 servers, it could benefit from virtualization. If your company has more than 10 servers, it could benefit from private cloud computing with a dedicated SAN and multiple physical host servers. The public cloud revolutionized Information Technology forever; the private cloud brings the benefits to the masses.
Conclusion: Save Money, Save Time, Sleep Easy: Transition to Private Cloud Computing
The private cloud is still a relatively new concept, but is based on some technology that has been around for a while and has proven itself for years. Besides providing some tremendous benefits of pooled computing resources and virtualization, it maintains the security and reliability of a normal dedicated server. The private cloud is not for everyone but a managed data center operator can make the transition to private cloud computing an affordable process and enable you to fully experience all of the great benefits of the private cloud.
