Abstract

A new class of distributed data stores, often referred to as NoSQL key-value stores, have recently been developed to support large-scale data-centric services. Cloud service offerings of these technologies combine their performance and availability Benefits with the flexible economic model of Cloud computing. Enterprises that have invested into Cloud technologies are now raising their expectations from best-e ort to guaranteed levels of service. Responding to this need, the research community is now focusing on data-centric services that support controlled performance, predictable reliability, and guaranteed I/O throughput. In this thesis we describe the architecture of a quality-of-service (QoS) infrastructure for achieving controlled application performance over the Apache Cassandra distributed key-value store. We present an implementation of our architecture and provide results from an evaluation using an extended version of Yahoo Cloud Serving Benchmark (YCSB) on the Amazon EC2 Cloud. A key focus of this thesis is on a QoS-aware measurement-driven provisioning methodology. Our evaluation provides evidence that the methodology is effective in estimating application resource requirements and thus in achieving the type of controlled performance required by data intensive performance-critical applications. While our architecture is implemented and evaluated in the context of the Cassandra distributed storage system, its principles are general and can be applied to a variety of NoSQL systems.
