Vrije Universiteit Amsterdam MASTER PROJECT - Parallel and Distributed Computer Systems - Resource Provisioning for NoSQL Datastores

Popular web applications like Facebook, Google Search Engine or Amazon have to face major challenges. First of all, the volume of data that has to be managed by these applications goes far beyond the limits of traditional data bases. As a reaction, a new generation of very scalable storing solutions, NoSQL data stores, has been design by the major Internet companies. Another important challenge that popular applications have to deal with is represented by flash crowds. In this context efficient resource provisioning is mandatory in order to avoid unpleasant situations like Amazon crashes from 2008 and 2011. This thesis addresses the problem of resource provisioning in the context of NoSQL data stores. First of all, we analyze the impact of different design decisions from the resource provisioning and we present the necessary steps toward building an accurate model for NoSQL solutions. As a proof of concept, our research presents the performance model of Cassandra, one of the most popular NoSQL implementations.
