SiDD: The Situation-Aware Distributed Deployment System

Most of today’s deployment automation technologies enable the deployment of distributed applications in distributed environments, whereby the deployment execution is centrally coordinated either by a central orchestrator or a master in a distributed master-workers architectures. However, it is becoming increasingly important to support use cases where several independent partners are involved. As a result, decentralized distributed deployment automation approaches are required, since organizations typically do not provide access to their internal infrastructure to the outside or leave control over application deployments to others. Moreover, the choice of partners can depend heavily on the current situation at deployment time, e.g. the costs or availability of resources. Thus, at deployment time it is decided which partner will provide a certain part of the application depending on the situation. To tackle these challenges, we demonstrate the situation-aware distributed deployment (SiDD) system as an extension of the OpenTOSCA ecosystem.
