It's safe to say that almost every enterprise is a user of virtualization, while a large majority also uses public cloud services. Cloud's popularity has generated increased interest in migrating from data center virtualization to private cloud, but many are still unclear about private cloud benefits and how to make that transition.
Before migration, a business must justify the use of private cloud instead of data center virtualization, especially since some private cloud benefits are similar to those of virtualization. There are two common advantages of private cloud. The first is that it's more resource-efficient than virtualization, and the second is that it's easier to hybridize with public cloud services. But those benefits aren't guaranteed for every organization.
After determining that private cloud is the right decision for your enterprise, IT teams must carefully plan the workload migration and resulting framework.
Weighing the benefits of private cloud for your enterprise
For companies with multiple data centers, private clouds are more economical than virtualization. In fact, the more data centers an organization has, the more private cloud makes sense. A private cloud creates a resource pool across all data centers, and this combination of resources creates a more efficient environment with lower costs. If an organization also centralizes the management of those data center resources into a single view, operations expenses will also be reduced.
Highly dynamic applications, which run on-demand and execute for a short time, are also better candidates for private cloud. Most cloud software suites will manage application dynamism easily and efficiently, and that may not be true of virtualization software. However, when applications are loaded and run for a long period of time, virtualization is just as efficient.
Most enterprises use public cloud services and expect to use more, and since they often combine those services with data center resources, a private cloud migration could facilitate hybridization. However, that can vary depending on the hybrid model.
For instance, some organizations use the public cloud as a back-up to their data center, either in the case of failure or to handle increases in workload. In this case, having a private cloud based on the same software and management tools as the public cloud will make hybridization easier, cheaper and more responsive. Deployment in either the public cloud or the data center would follow the same practices, and management of the environments would be very similar. However, if public cloud applications only supplement, but don't substitute, data center applications, virtualization is sufficient.
