Design Patterns to Enable Data Portability between Clouds´ Databases

Cloud providers offer their infrastructure, platform and software to customers who found cloud computing as an appropriate solution for their requirements. The companies who want to choose a cloud provider should be noted that after developing their own software in a specific cloud environment, the migration to another cloud environment would be difficult or it might be impossible. Cloud databases are responsible for storing data in a scalable and high available way in cloud environments. This paper provides a solution for enabling portability between column family databases and graph databases as cloud databases by proposing design patterns.
