The adoption of the cloud computing paradigm is associated with increasing security concerns. Cloud computing service models (SaaS, PaaS and IaaS) are exposed to different security threats in each level of services. The Trusted Cloud Computing Platform (TCCP) proposes a security model that protects customers VMs at the IaaS level. In this paper, we investigate methodologies for the specificatio...

As happened previously in electronics, software targeted at consumers is increasingly the focus of investment and innovation. Some of the areas where it is leading is animated interfaces, treating users as a community, audio and video information, software as a service, agile software development, and the integration of business models with software design. As a risk-taking and experimental mar...

Software Performance is a critical aspect for all software products. In terms of Software Operation Knowledge, it concerns knowledge about the software product’s performance when it is used by the end-users. In this paper the authors suggest data mining techniques that can be used to analyze software operation data in order to extract knowledge about the performance of a software product when i...

Software vendors and software service providers can no longer function without taking their software ecosystem into account. Software vendors presently face three challenges in regards to software ecosystems: (1) they require insight into software ecosystems, (2) they require insight into the possible survival strategies that exist for software ecosystem participants, and (3) they require an ov...

The CAST project is putting forward a novel ecosystem-oriented model for developing and deploying enterprise applications on future cloud application platforms. One of the most fundamental challenges that this model is raising concerns how to support platform governance. In this demonstration, we present the registry and repository solution that was created to address the platform’s requirement...

Since its inception, SaaS market has been one of the fastest growing segments in the software industry. This paper is the first attempt to measure the productivity of pure-SaaS firms by adopting a stochastic frontier approach. Using an annual dataset from 2002 to 2009, we conduct a two-stage analysis. In the first stage, we derive the efficiency scores of each SaaS firm. We found average techni...
