Recently, the economy has taken a downturn, which has forced many companies to reduce their costs in IT. According to experts, one interesting approach could be to outsource parts of their business through third parties. This will allow companies to free resources invested in outsourced business processes and to focus their investments on those processes that are unique to the organization. The future Internet will be based on services and this new trend will have significant impact on domains such as e-Science, education and e-Commerce. Recently, SaaS (Software-as-a-Service) has emerged as a model of software deployment suitable for implementing this new service-oriented strategy.
