Rather than throwing hardware at data warehousing problems by relying on expensive clusters or specialized "appliances", the scalability offered by LucidDB's unique architecture allows you to achieve great performance using only a single off-the-shelf Linux or Windows server. Besides keeping costs down, this also minimizes maintenance and administration hassles.
