Heretofore Big Data Small Business was an oxymoron No longer.
If, as this link suggests, Big Data is the disruptive IT capability of 2012, then SMBs had better pay attention. And easy access to cloud integration is an important part of the mix. The proximity of the SMB data to inexpensive cloud-based analysis tools matters as well. Over the wire number crunching can be slow, so you'll need to decide whether you need real-time analysis on-site or can stage your data to cloud storage and update it daily for analysis.
Either way, the cloud is the key feature if you want it to be cost effective.
