The Internet is no longer just a source for accessing information; it has become a valuable medium for social networking and software services. Web-browsers can now access entire software systems available online to provide the user with a range of services. The concept of software as a service(SAAS) was born out of this. The number of development techniques and frameworks for such web-applications has grown rapidly and much research and development has been carried out on advancing the capability of web scripting languages and web browsers. However a key part of the life-cycle of web-applications that has not received adequate attention is deployment. The deployment techniques chosen to deploy a web application can have a serious affect on the cost of maintenance and the quality of service for the end user. A SAAS modelled web application attempts to emulate a desktop software package experience. If a deployment process affects the availability and quality of service of a web-application then the core concept of this model is broken. This dissertation identifies approaches to designing a deployment process and the aspects that influence the quality of a deployment technique. A survey was circulated to a number of Irish small to medium sized enterprises (SME) that develop web-based software. The survey shows an overview of multiple deployment processes used by these SMEs. Using this information, along with a review of the available literature and a detailed case study of a typical SME deploying SAAS based products, the dissertation provides a critical analysis and evaluation of the current deployment techniques being used.
