Service-oriented architectures have been a mainstay of business computing and there is a growing interest in services for a variety of environments with heterogeneous systems, specially where large-scale dissemination is essential. Thus, peer-to-peer services have become very important given the growth of the Internet-of-Things (IoT) and the propagation of smart devices.

As a result of this research, a framework providing fault tolerance at the application and communications level was built. In this way, developers are able to implement reliable distributed applications, even when using devices with limited computing resources.

Filipe Campos admits that completing a PhD (initiated in 2007) with a grade of "very good" makes him "very pleased with the end of a long marathon, with some difficult stages along the way". It is also worth mentioning that José Orlando Pereira, professor at the School of Engineering of the University of Minho and researcher of HASLab, was the supervisor of this scientific work.
