Abstract

Interactive Voice Response (IVR) applications are ubiquitous nowadays. Automated attendant, bank teller and automated surveys are a few of many applications requiring IVR capabilities. Cloud computing is a paradigm gaining a lot of momentum. It has three major service models: Infrastructure as a service – IaaS, Platform as a service – PaaS, and Software as a Service – SaaS. It offers also several inherent benefits such as scalability, resource efficiency and easy introduction of new functionality. However, very few, if any, IVR applications are offered today in cloud-based settings despite of all its potential benefits.
This thesis deals with IaaS. Accordingly, we propose a novel architecture for a virtualized IVR infrastructure that relies on RESTFul Web services. The architecture proposes IVR substrates that are virtualized, composed, and assembled on the fly to build IVR applications. As a proof of concept, we have implemented an IaaS prototype on which performance measurements have been done to evaluate our architecture concept. In addition, a simple proof of concept PaaS consisting of a graphical user interface (GUI)has been built to enable the development and management of simple IVR services in the SaaS layer.
