Design And Implementation Of Tcp Communication Between Cloud Foundry Applications

With the development and maturity of distributed computing, virtualization technology and other traditional computer technology, as well as the demand of computation and storage in Big Data Era, the cloud computing technology came into being and is concerned by industry-wide because of its good prospects.PaaS (Platform as a Service) is a form of cloud computing and it can provide the necessary platform for running software. Cloud Foundry is the first open source PaaS platform; users can deploy applications on Cloud Foundry swiftly.Currently, Cloud Foundry can only supports Web applications, thus applications deployed on Cloud Foundry cannot communicate with other processes via Tcp protocol, which limits the versatility of Cloud Foundry, and has become a bottleneck in deploying many traditional applications on the Cloud Foundry.In this paper, we modify and expansion existing components of Cloud Foundry, and make Cloud Foundry can support Tcp communications between applications on it. When there are multiple instances of an application, the paper also presents different port mapping strategies for users to choose. Finally, a series of tests is designed to test the function of the system which should be completed.
