Provisioning of component-based applications across multiple clouds

Abstract

The several existing Platform-As-A-Service (PaaS) solutions are providing application developers with different and various offers in terms of functional properties (e.g. storage), as well as, non-functional properties (e.g. cost, security). Consequently, developers may need to provision components of the same application across several PaaS depending on their related requirements and/or PaaS capabilities. This paper proposes generic mechanisms that allow seamless component-based applications provisioning across several PaaS. These mechanisms are based on the COAPS API; an already defined OCCI-compliant API that allows provisioning of monolithic applications in PaaS using generic descriptors and operations. To illustrate the proposed mechanisms, the paper showcases a realistic use case of provisioning of a JEE-based simulation application across Elastic Beanstalk and Cloud Foundry platforms.
