With the increasing adoption of business models relaying on Cloud Computing, digital platforms and servitization, IT providers have been trans-forming their solutions into services-based, having as a goal facilitating their binding to clients’ applications. In this formed wide and open service-oriented environment, classical static services binding approaches are limited to support the business dynamics of Virtual Organizations (VO). As services would assure VO members’ systems operation, a bad services selection may hazard that. We argue, though, that services selection criteria, largely based on QoS and costs, are not enough to provide higher confidence to VO members when selecting services from such open ecosystem of service providers. In this line, this paper proposes a more comprehensive and multi-criteria decision-making model for dynamic services discovery. A prototype has been implemented and results are discussed.
