As organizations discover the value of software as a service/on-demand BI, its adoption is becoming more mainstream.  Even though touted as targeted to mid-market companies because of the lower costs and lack of on site management, the reality is that many enterprise organizations are deploying on-demand BI solutions at the departmental level. Although this is a fairly widely known fact, I wonder whether SaaS based models will still be more cost effective in the long term? With the increasing availability of on-premise solutions that are less costly and more user friendly, or business user centric, I wonder if the hype of SaaS will continue to increase within the market or whether alternative solutions, or those that are considered mainstream will start to make more inroads into companies that are looking for low cost BI and choose SaaS due to its lower subscription fees.
