The goal of virtualization in the data center is to help the enterprise achieve a business goal, whether that goal is consolidation, reduced management and head count costs, disaster recovery, or even "going green." And with this, the pinnacle of virtual solutions is to architect and deploy the complete Virtual Data Center. But before that goal can be achieved, the current state of any data center needs to be assessed and goals for where that data center need to be defined. F5's Virtual Data Center Maturity Model provides a means to achieve both of these goals, while also creating a firm map of what virtual technologies help move the enterprise through the level progression. While most enterprise data centers won't need to reach Level 5, moving up the model to the point where virtualization is implemented to achieve the business goal of application delivery is paramount to any enterprise. This White Paper defines the baseline and process of virtualization maturity for the data center.
