This chapter presents a generic ‘ambient assisted living as a service’/‘enhanced living environment as a service’ platform. Multiple platform elements are described by taking into account layered hierarchical models, horizontally and vertically planning models as well as models with planes. The main goal of the work is to identify the important platform parts, classify the existing models, and create a framework that will allow further protocols and services classification. The chapter starts with a presentation of the end-user requirements, continues with the analysis and design phases, and ends with a possible implementation of the platform as a cloud-based one, aiming to aggregate data from multiple different access and edge technological solutions and islands, and allowing data analysis and mining at the abstract level. This is considered as a driving force for further development of possible business solutions. The work is based on a real-life experience gained within living labs and conducted surveys on the topic.
