Should the data warehouse be deployed on the cloud? IDC addresses this question on a regular basis. As adoption of cloud software increases, organizations of all sizes across industries and geographic regions are evaluating and assessing the opportunities and challenges of deploying software on the cloud. Data warehousing solutions are no exception to this trend. Data warehouses have been in use since the mid to late 1970s. Substantial investments have since been made in technology and labor to develop, deploy, manage, and maintain data warehouses of various sizes. IDC research indicates that, during the past quarter century, about $100 billion in aggregate has been invested in data warehouse software alone.
