The biggest advantage of Microsoft Parallel Data Warehouse is the possibility to stop or pause the service because it can be very expensive, and the ability to pause the service when I don't use it is probably the main feature, along with the possibility to handle huge amounts of data, which is quite an interesting capability of the service. Microsoft Parallel Data Warehouse can be a cost-saving solution, but in general, it's considered to be an expensive service. If I know how to handle it, it can be cost-saving, especially with the feature I mentioned earlier about pausing the service when I don't use it, which is a significant cost-saving feature. Still, at the end of the day, it remains somewhat expensive, making more sense for very specific use cases where I have to handle huge amounts of data; for medium or small use cases, it doesn't really make much sense.
