Abstract

Cloud computing, for instance provided by Eucalyptus, becomes more and more popular because it facilitates the construction of scalable applications. However, the horizontal scaling is not solely exhausted by web application in a cloud. Additional techniques for horizontal scaling are required. This paper describes Eucalyptus and Amazon EC2, and investigates the performance of the online-adaptation framework SLAstic utilizing Eucalyptus for automatic scaling of an example web application. The paper presents a performance evaluation of SLAstic utilizing Eucalyptus incorporating a fixed number of nodes scenario and a varying number of nodes scenario. It shows that web applications running in Eucalyptus can automatically scale up and down with the usage of SLAstic. The results are demonstrated on the basis of JPetstore with a simulated typical day-night-cycle load for web applications.
