Cloud computing has opened up a new way of doing business by hosting and delivering services over the Internet. This business model has allowed many organizations to save money and time and more importantly to focus on their core business. Today, organizations which have adopted the new paradigm are not looking back (e.g. NASA cloud migration success story). However, despite all those benefits, there are still organizations which are unwilling to migrate their legacy applications in the the cloud due to the lack of proper migration methodology and risks and benefits involved. In this paper, we present the key concepts of cloud computing and legacy code and then, we present the state-of-the-art of migrating a legacy application in the cloud by focusing on five frameworks : ARTIST, Cloud-RMM, REMICS, CloudMIG and Legacyto-Cloud Migration Horseshoe framework. This will allow to suggest some recommendations with the goal of convincing more organizations to adopt this paradigm.
