The Node.js based web application Entize Planning needs to evolve and become distributable, and the logical transformation is into a SaaS cloud service that can compete in a pressured economic climate concerning resources. The aim is to provide an insight into the challenges in mitigating a web service to the cloud. By utilising the edge concerning low-cost and rapid development associated with Open Source use, a NoSQL supported and Node.js with related technologies, cloud service prototype development process and environment is proposed. Keeping guidelines such as: security, maintenance, complexity, scalability and mobility; emphasised, in order to carefully utilise existing architecture will result in an flexible solution that preserves aforementioned attributes, making the project as a whole a success towards its endusers. Key remarks that surfaced was the distinct separation between Entize Planning - the product - and the delivery mechanism - the cloud service plattform - and also the explicit need to investigate any utilisation of preexisting cloud architecture pertaining limitations in their delivery, before adoptation.
