This paper focuses on Platform as a Service (PaaS). From the advent of Cloud computing, the latest trend has been to design ad hoc platforms specialized to address given operational scenarios. In this context, the need of an adaptable, fault tolerant and secure cloud platform for the development of specific PaaS is becoming more and more compelling. In this work, we present the Distributed Resilient Adaptable Cloud Oriented (DRACO) PaaS. DRACO PaaS is more than a cloud platorm. In fact, it introduces a new development model for PaaS. More specifically, we will focus on how DRACO PaaS can be adopted for the development of any kind of specialized PaaS.
