Abstract. As cloud computing infrastructures are growing, in terms of usage, its requirements about software design, management and deployment are increasing as well. Software-as-a-Service (SaaS) platforms play a key role within this cloud environment. SaaS, as a part of the cloud offer, allows to the software providers to deploy and manage their own applications in the clouds in a subscription basis. The problem with the current SaaS offers is the lack of openness of in their platforms and the need for learning a whole new paradigm when trying to initiate in the SaaS market. Big players, such as: Amazon, Google or Microsoft, offer their proprietary SaaS solutions. Another consideration is the amount of current Web applications that need to be re-engineered into this cloud paradigm. This research work aims to reduce the effort required to enter into the SaaS market by presenting an architecture based on open source components for developing, deploying and managing SaaS applications.
