Early adopter users have already deployed a variety of business intelligence (BI) tools and data warehouse (DW) platforms on clouds, thereby proving the concept. These pioneering deployments have demonstrated that both public and private clouds give BI and DW the same advantages for fluid resource allocation and scalability that they have given to operational and transactional applications. In fact, some organizations have a relatively mature private cloud within the enterprise – originally put in place for operational applications – and so are approaching the time for BI/DW teams to migrate their tools and platforms onto it.
It’s still early days for BI and DW on a cloud, but a number of interesting trends have already arisen. BI/DW users prefer private clouds, but also use public clouds to try out BI prototypes before committing them to an enterprise cloud. Also, some departments put their BI solutions on a cloud, because it’s cheaper, faster, and less complex than dealing with central IT. A few vendors offer BI, DW, data integration, and data quality tools via SaaS on clouds. Advanced analytics and enterprise reporting seem to be the most popular BI types deployed on clouds at the moment. But various types of data warehouses, marts, and analytic databases are also seen there. TDWI expects that within three years, the full complement of BI and DW tools and platforms will be commonly found on clouds, especially private ones.
