From a purely operational point of view, the answer to the question above must be a yes. The long term investment that comes with having a dedicated server hosting service is that you get to cut down the costs that you may eventually require for additional network set up and equipment acquisition. The dedicated server hosting service will provide you with a reliable platform that removes the need for additional support and more investment in future. As such, a rational operations manager will look at such situation and acquire the dedicated server hosting service.
Take the simple case of a supermarket, such a system is expected to operate at its optimum level every day without fail and deliver accurate results or else the customers will complain or the business will lose money. The points of sale systems are essentially expected to maintain reliable accurate and up to date data that can be audited at any time. In such a case, the importance of dedicated server hosting is more pronounced. Additionally such a system is expected to track the inventory movement not only in the supermarket but also in the store. Now imagine such a system being deployed over more than 1000 branches or across different geographical regions of the world. Without a dedicated server hosting service, such a system would crumble. However, the choice on whether you as a business needs the dedicated server hosting service is entirely reliant on the business you run and the scale on which you operate.
