Abstract :
We analyze the issues related to the management of sessions in Web Applications running on Auto Scaling IaaS systems. We focus on the effect of scaling operations (i.e., dynamic addition/removal of virtual machines) on the Sticky Session paradigm provided by Web Servers. We propose two different solutions, namely Session Monitoring and Session Migration, and describe the implementation of the former in the Open Source Eucalyptus IaaS system.
