Multi-PaaS Provisioning

Sami Yangui & Mohamed Mohamed

Institut Mines-Telecom, Telecom SudParis.

Summary: The study we have conducted of existing cloud platforms shows that their

  • perating requires the use of specific and proprietary APIs. This PaaS providers’ policy is

hampering the interactions between different clouds. If appropriate solutions are not considered, this issue would for instance slow down the democratization of clouds federation and cooperation. As a part of our work, we developed a generic PaaS application provisioning and management API named CompatibleOne Application and Platform Service - COAPS. Our solution applies the separation of concerns principle by separating the provisioning and the management API from the defined description model.

  • PaaS operating requires the use of specific and proprietary APIs

– Issue: Cooperation and interactions between different clouds

  • Motivating example

– Provisioning of a Web application (WAR archive)

  • – Requirements to be provisioned by the hosting PaaS

– Apache tomcat as service container – MySQL as database service

Application provisioning Issues

  • Provisioning steps are specific per PaaS provider

– Not the same commands – Not the same inputs – Not the same order of creation

However,

  • They have all the same semantics

OCCI-compliant API to manage and provision PaaS resources

COAPS API

  • PaaS-independent approach for the provisioning and

management of applications in the Cloud

  • Resource description manifest to express user requirement
