This paper examines value networks in cloud computing. It demonstrates the kinds of value offered by such networks to firms within a given network, and considers how and why the network may change over time.

This article explores two ways to integrate Microsoft Secure Development Lifecycle (SDL) for Agile practises to an ongoing software development project. The project itself uses the MSF Agile 5.0 software development process. Agile software development processes have gained acceptance in the software industry to develop software (West et al. 2010). Security can be seen as a direct customer need and so agile software development methods should include security aspects in their development process. Microsoft's SDL for Agile is one method to combine agile process with security.

Cloud is a new interaction, development and service delivery paradigm in which services and data are stored in servers managed by external parties. User experience (UX) is an important design target and success measure for new services, especially when the users have plenty of choice within the quickly expanding service offering. From the user’s point of view, the cloud concept may facilitate better user experience but the concept may also raise new challenges. UX targets for the cloud are still undefined in research. In this paper, we will identify key user experience issues related to cloud services in six design and evaluation cases. Based on the findings, we propose research questions for initial research agenda  on UX in the cloud.

The emergence of asynchronous techniques for building interactive web applications has led to the development of Rich Internet Applications (RIAs). RIAs offer greatly enhanced usability and the ability to deliver rich dynamic content. However, due to the widespread use of RIAs, there is a need to develop and test highly scalable RIAs. Furthermore, cloud computing introduces new opportunities for ensuring and extending the performance and scalability of RIAs. This has necessitated the need to devise effective ways for doing automatic performance and scalability testing of RIAs.

In their research article, Niclas Snelmann, Adnan Ashraf, and Ivan Porres describe different problems and challenges in automatic performance and scalability testing of RIAs. They then propose the ASTORIA framework as a novel solution to the identified problems and challenges. The effectiveness of our proposed approach is demonstrated by building a working prototype for ASTORIA and by using it for conducting experiments.

In this article we present the design of a database adapter for the Google Datastore and the Vaadin Rich Internet Application Framework. The adapter allows us to develop Vaadin applications that can use different database systems and can be deployed in a private infrastructure as well as in the Google App Engine platform. The adapter uses a two-level cache schema to improve performance and reduce operation costs. Experimental results show that the use of the adapter does not hinder the ability of the Google App Engine platform to scale web applications on-demand to high loads.
