In this session we'll introduce NoSQL databases and the movement's emerging patterns. We will contrast them to the concepts presented in workshop 1 (attendance is not mandatory). We will discuss a few of the most common open source NoSQL databases, their strengths, use cases, and their operational stories when running in the Cloud. Note: This talk is aimed to developers
