The Future of Service Marketplaces in the Cloud

Towards a Fuzzy-oriented Framework for Service Selection in Cloud e-Marketplaces

“…In cloud service e-marketplace, service providers should be able to join the ecosystem easily, and user should conveniently express subjective requirements (Akolkar et al, 2012), and to particularly explore services without being overwhelmed by so many choices. The main contribution of this paper is a cloud service selection framework that incorporates mechanisms to: 1) compose atomic services on the fly to satisfy complex users' requirements; 2) allow users the flexibility of expressing QoS requirements; both preferences and aspirations, and do so using subjective descriptors that is more akin to human judgment; 3) reduce choice overload by showing only the top best services in a manner that facilitates easy comparison for effective decision making.…”

“…The growing popularity of cloud services requires service selection platforms that enable the composition of atomic services to satisfy complex user requirements, and highlight the quality of services (QoS) attributes of these value-added services under one e-marketplace structure (Akolkar et al, 2012;Gatzioura et al, 2012). Despite their successes, commercial cloud e-marketplaces (e.g.…”

“…In addition, search results on these platforms are presented as unordered lists of icons, with little or no comparison apparatus that simplifies decision making. Existing cloud selection approaches (see Figure 1) do not currently provide the sophistication to optimize user experience in the e-marketplace (Akolkar et al, 2012). For example, some approaches only allow users to make selection from a predefined list of atomic services, which does not address complex situations where a user's requirements extend beyond what atomic services can provide (e.g.…”

“…The CEFM is mapped as a constraint satisfaction problem, and the Choco-based reasoning engine (www.chocosolver.org) reasons with a Depth-First search algorithm to derive all valid mappings. Possible combinations of atomic services that can be generated from the pool of atomic services are made available in the e-marketplace based on former composition approaches (Akolkar et al, 2012).…”

Towards a Visualization Framework for Service Selection in Cloud E-Marketplaces

“…Cloud service e-marketplaces are online internet platforms for trading cloud-based services, by providing mechanisms for enabling service composition, service discovery, service selection, service deployment, service monitoring, and payment resolutions in a single one-stop shop infrastructure [12,13]. The e-marketplace provides a unified view of all available offerings and becomes a single point of access to offerings available in the cloud ecosystem.…”
