The Private PaaS is an open source Platform as a Service (PaaS) solution implemented on Apache Stratos. It is a multi-tenant, self-service, metered, middleware cloud for complex, enterprise-ready projects. It can be run on Google Compute Engine (GCE), Amazon EC2, OpenStack, CloudStack and Google Kubernetes. Currently WSO2 Private PaaS has a RDBMS which contains cloud service usage information, however it does not have a billing system. In this project it is required to implement a web based billing system which could integrate Google Checkout for generating invoices and making payments for cloud service usage.
As the first step of this project a literature review needs to be done analyzing existing billing models of PaaS solutions and design a billing model. This should be configurable via the Web application according to custom billing requirements. Once the billing model is in place the web application needs to be implemented to generate a detailed invoice based on the Infrastructure as a Service (IaaS) resource usage and PaaS service usage. This also needs to consider the profit margin of the PaaS provider. Finally an aggregated invoice needs to be generated for the cloud user. PaaS administrator should be able to login to the billing system and view detailed billing information of each PaaS user.
