A great whitepaper on "NoSQL and the Windows Azure platform" written by Andrew Brust, a frequently quoted technology commentator and consultant.
This paper is important because there is a renewed interest in certain non-relational data stores which are sometimes collectively referred to as "NoSQL" technologies and this is a category which certainly has its niche of avid supporters. NoSQL databases often inherently use approaches like distributed horizontal scale-out and do away with some of the ACID characteristics of traditional relational databases in favor of flexibility and performance especially for certain workloads like scalable web applications.
This in turn provokes a number of questions as to which scenarios NoSQL is appropriate for, whether it is a favored technology for the cloud and how it relates to cloud offerings like the Windows Azure platform.
