Abstract: Platform as a service (PaaS) supports application developers with the ability to implement and deploy their applications in the cloud. Several heterogeneous PaaS platforms are available, such as Google App Engine (GAE), Windows Azure, Cloud Foundry, and OpenShift. Each PaaS provider has its own proprietary implementation and deployment APIs. The heterogeneity of these APIs makes developers worry about their application portability and interoperability. The work in this paper concerns about the heterogeneity of different PaaS implementation APIs. Standard PaaS implementation APIs, called Std-PaaS APIs, have been proposed to solve the application portability problem. Std-PaaS APIs allow developers to develop generic cloud application by writing their applications once and deploying many times on heterogeneous PaaS providers. Std-PaaS APIs have been evaluated using two case studies, in which generic APIs for cloud persistentstorage service and NoSQL datastore service have been developed and used to developed applications to be deployed onto GAE and Windows Azure.

Keywords: platform as a service; PaaS; vendor lock-in; standard API.
