Cloud computing and BI (Business Intelligence) are technologies of choice to address today's business needs. They allow companies to optimize IT and become more competitive and productive. Implementing BI solutions in the cloud brings not just benefits, but also new challenges that need to be addressed. On technology side there are security, communication infrastructure (increasingly mobile) and speed. New technology and business models are arising because the authors are dealing with large quantities of distributed data which BI can (and often have to) use as new sources of information. Combining these data sources with new cloud services may significantly change the way some businesses are being run today.
