Multi-cloud Platform-as-a-service Model, Functionalities and Approaches

Abstract

Platform-as-a-Service (PaaS) is the Cloud area concentrating the major growth in the last years in terms of adoption and market share. At the same time Cloud models are evolving towards Hybrid Clouds through the consideration of service expansion across a diversity of Cloud offerings. So far, the majority of multi-cloud approaches have explored IaaS layer, neglecting the rest of the Cloud stack. This limits enterprises to enjoy the benefits of an agile, automated and adaptable infrastructure though flexibility provided by PaaS multi-cloud. This paper presents and compares results of two research projects addressing PaaS multi-cloud architectures: ASCETiC and SeaClouds.
