Applications and services hosted in the cloud are increasing continuously. Cloud technology offers important perspectives (performance, high availability, elasticity) and it enables new business models. Unfortunately, this new paradigm faces unprecedent requirements not addressed in legacy application (multi-tenancy, scalability, etc.). This leads to complex re-engineering phases in order to to migrate existing software into a cloud environment. Before starting a migration, it is important to analyze the cloud compliance of the application, what to expect after the migration and the effort required to fulfill these expectations. This paper assesses a way to extract an index that describes the feasibility of the re-engineering. We test the metric with a real application that needs to be migrated to a private cloud.

Abstract

Applications and services hosted in the cloud are increasing continuously. Cloud technology offers important perspectives (performance, high availability, elasticity) and it enables new business models. Unfortunately, this new paradigm faces unprecedent requirements not addressed in legacy application (multi-tenancy, scalability, etc.). This leads to complex re-engineering phases in order to to migrate existing software into a cloud environment. Before starting a migration, it is important to analyze the cloud compliance of the application, what to expect after the migration and the effort required to fulfill these expectations. This paper assesses a way to extract an index that describes the feasibility of the re-engineering. We test the metric with a real application that needs to be migrated to a private cloud.
