Establishment of cloud architecture vision

Cloud services are holistic approach for to maintain business processes, business data, busi-ness applications and infrastructure. There are several models and service forms of cloud on the market, so enterprises have has multiple choices to consider and take in account to find proper way to utilize cloud services for the business. This master thesis work is using qualitative research approach to investigate cloud services and cloud models using several literature sources and up to date articles to gather valid infor-mation about cloud services for the research. Enterprise architecture methodology Togaf, with requirements management forms up the theoretical framework of this research. By using this approach, gathered business objectives, constraints and threads are processed and analysed against cloud adoption initiative for insurance industry, which works as the request for archi-tecture work within this research. These business requirements are based on commercial sources, investigated and described at the beginning of research. Research is using Togaf’s architecture development methodology (ADM) to form up architec-ture vision, where selected business area for applying it is a insurance industry. Research has boundaries aligned on ADM:s preliminary phase and architecture vision phase which leads to outcome of reference architecture vision. The objective is to build appropriate model for en-terprises which intent is to adapt cloud services for its business
