Design Patterns to Enable Data Portability between Clouds' Databases

Abstract

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.
