Private Clouds

An interesting trend emerging is the concept of "Private Cloud" in the Data Center Management Area.

This trend eventually combines the strengths of
a. Standardization of overall infrastructure based on open standards
b. Virtualization of server resources
c. Seemless Provisioning of applications
d. Pay-as-you-go billing models and charge back of IT resources based on consumption
e. Services oriented architecture (SOA)

Their main advantages over the "PUBLIC clouds" are
1. less risk of security related issues
2. more control over the network bandwidth and availability

In my opinion, some big IT houses will adopt to "Private Clouds" to get the benefits of cloud computing while keeping the control in-house in the short term. As the technology advances and matures, it will also benefit the PUBLIC CLOUD providers!
