cost of operations as well as management. The management costs of such a new breed of application delivery controller are inherently lower than a traditional application delivery solution, owing to its virtualized architecture and the ability for the device -- and IT manager -- to manage the system as a single entity rather than as individual blades in a larger system. This reduces the amount of management necessary, and in turn reduces the costs associated with managing the device. This is especially true as capacity is added, as it would require multiple legacy chassis-based devices to match the processing power of a single virtualized chassis-based system. Each added device must be managed, and adds to the amount of power consumed and BTUs generated, making it much more expensive to scale. Also having an impact are the BTUs generated by each device. There is a definitive cost associated with removing the heat generated by these devices in the form of cooling, so the lower BTU generation of the new breed of chassis-based solution is a definite boon both on the environment as well as on the budget. Conclusion It's rare that an environmental friendly movement such as Green IT results in reducing costs, especially in its early stages. And yet in the case of this new breed of chassis-based application delivery controllers, that's exactly the result. With the decreased management and power consumption costs and increased performance, these new application delivery controllers are both green as in grass and green as
