Cloud P-TOSCA porting of N-tier applications
Marjan Gušev, Magdalena Kostoska, Sasko Ristov · 2014
The desire to move the applications from on-premise to cloud or to move it between the clouds gives a precious freedom to the clients and enables them to freely change the cloud service provider. The ability to move the application is a hot research topic and is not solved completely yet, neither by the vendors, since they prefer client lock-in, nor by cloud providers, that have great challenges to realize the task. Although several standardization efforts are on-going, still there is no offered solution, flexible enough to satisfy free porting from one cloud to another. In this paper we explain the P-TOSCA engine, which acts as a PaaS and enables automated portability. Our goal is to demonstrate its domain of application on a general type of a N-tier application and move the application between Eucalyptus and OpenStack clouds.
