dc.description.abstractThe advent of cloud computing alongside with pervasive form factors such as smart devices, introduces a new meaning to asymmetric system models. These new clients act as a presentational layer alleviating much of the computational and storage concerns to cloud services. The application platforms associated with these creates new opportunities for third party developers to provide domain specific applications (apps) to smart devices. Restricted interaction surfaces on smart device introduce new challenges to how apps are managed on these. Moreover, for security purposes as well as strict resource requirements, apps running in these environments are commonly subject to very strict isolation. We conjure that there are benefits with allowing automatic configuration apps onto a client system. Furthermore, we suggest that integration between apps residing at the same host, as well as different hosts, is beneficial to system functionality. By enabling this we could alleviate much of the interaction necessary for users and reduce the time consumed in using such smart devices. The concrete asymmetric system explored in this thesis is the Windows 8 app platform. This platform poses several hindrances to our conjecture. For security reasons, automatic configuration of apps onto a client system is prohibited. Apps run inside a sandboxed environment where they are isolated from the system and other apps. Access to resources is prohibited unless explicitly allowed by the user. As a consequence, communication between apps is forbidden. This is further complicated by the fact that apps in this environment are suspended when not in use. This thesis introduces Javza, a runtime to support dynamic app configuration and integration in Windows 8. Javza provides support for automatic installment of apps based on simplified contextual information. Furthermore, it provides app integration by allowing apps to share data, both within the same and across different systems. We present and evaluate the associated performance costs of deploying Javza inside a Windows 8 environment. We further evaluate the applicability of Javza by implementing a specific use case involving collaborative search. Lastly we discuss some of the security implications associated with our design, and some future improvements in Windows 8 to support our conjecture.en
