The combination of the cloud and the on-premise data center is one that can create mixed emotions among data center managers. These individuals often want trust the cloud, but they also don’t want to give up control over their servers and their data. A workable alternative is the private cloud, but it is not without its own set of complications. This creates an opportunity for appliance deployment to bridge the gap between the internal data center and the cloud.
The realities of the private cloud were examined in the June issue of Internet Telephony. In “Some Harsh Private Cloud Realities,” Jeff Hudgins, vice president of marketing at NEI (News - Alert), highlighted how the regulatory environment within the data center can cause complications when creating the private cloud.
Data center managers are used to regulatory auditors who do things in a very specific and very safe manner. As a result, the data center manager takes a server-hugging approach, believing that he must show the specific controls in place to manage customer and financial data, even when leveraging the cloud.
Aside from the lack of agility in the aforementioned data center, there is also a limitation of virtual machine scaling necessary to cover the demands of the everyday workload. Efficiency and redundancy in appliance deployment are generally sought when implementing virtualization technology in the network; but they are never guaranteed.
Recovering from any type of failure is a challenge and data center managers tend to add and take away resources incrementally. This approach to appliance deployment eliminates the benefit of the instantly scalable environment.
Cost is another primary concern. Because data center managers are inherently conservative, they have a tendency to provision everything from processing power to storage, attempting to build in some margin for uptime assurance. This margin in any appliance deployment can drive up the cost of the environment, eliminating any expected savings the cloud environment is designed to provide.
Ultimately, leveraging appliance deployment to create the private cloud within the data center can deliver cost savings and scalability, but the right automation tools must be in place. These tools enable data center managers to provision when they need it, and only what they need. This approach to appliance deployment ensures they can meet the performance and cost goals set by upper management, while also maintain the performance levels that keep the business running smoothly.
