In the last decades, the increasing complexity of industrial information technology has led to the emergence of new trends in manufacturing. Factories are using multiple Internet of Things (IoT) platforms to harvest sensor information to improve production. Such a transformation contributes to efficiency growth and reduced production costs. To deal with the heterogeneity of the services within an IoT system, Service-Oriented Architecture (SOA) is referred to in the literature as being advantageous for the design and development of software to support IoT-based production processes. The aim of SOA-based design is to provide the leverage to use and reuse loosely coupled IoT services at the middleware layer to minimise system integration problems. We propose a system architecture that follows the SOA architectural pattern and enables developers and business process designers to dynamically add, query or use instances of existing modular software in the IoT context. Furthermore, an analysis of utilization of modular software that presents some challenges and limitations of this approach is also in the scope of this work.

With the introduction of paradigms like Internet of Things, Cyber Physical Systems and Cloud Computing, Smart Factories are becoming a central part of today's manufacturing systems. Even though there already are some solutions in the market the full potential for smart manufacturing hasn't yet been achieved. In order to fulfil the gap European researchers are developing vf-OS, a platform that aims to be the future reference in future factories operating systems. In this work is presented some preliminary results regarding the modules related to IoT, event processing, situational awareness and data harmonization that are being researched in the scope of vf-OS to achieve holistic solution for industries, specifically targeting the agriculture domain.

Nowadays, with the increased integration of cloud-computing, data integrity continues to be a problem in the current eHealth sector. This security principl
