Abstract
This paper describes CloudStore, an open source application that lends itself to analyzing key
characteristics of Cloud computing platforms. Based on an earlier standard from transaction processing, it
represents a simplified version of a typical e-commerce application – an electronic book store. We detail
how a deployment on a popular public cloud offering can be instrumented to gain insight into system
characteristics such as capacity, scalability, elasticity and efficiency. Based on our insights, we create a
CloudStore performance model, allowing to accurately predict such properties already at design time.
