Cloud application infrastructure services, also known as Platform-as-a-Service (PaaS) form the foundation of a cloud computing platform. The key role of PaaS is to enable development, execution, management and life cycle control for cloud-based application solutions. Integration platform as
a service (iPaaS) is a suite of cloud services aimed at addressing a wide range of cloud, Business-to-Business (B2B), and on-premises integration and governance scenarios. This paper proposes iPaaS approach in the field of traffic safety. The proposed framework is based on combining information integration and portal integration in the cloud computing technological environment. Information integration is carried out in a common SQL Azure database. The portal integration is enabled with Windows Azure hosted services. The proposed model was implemented in a case study of integration of information systems that are used for the railroad crossings management in the Serbian Railways.
