Is the Relational Database Not an Option in Cloud Computing?
Recent focus on Cloud Computing has increased the use of key/value databases. The most common theme for this is scalability. Though scalability is a key factor, cloud computing has other advantages that makes it attractive for vendors that do not need to deliver highly scalable applications or services.
