Entwicklung einer Methodik für die Migration der Datenbankschicht in die Cloud

Abstract

This diploma thesis identifies different Cloud data migration scenarios like outsourcing, replication, data synchronization, backup, archiving, scalability enhancement, Cloud burst, sharding or data import and puts them into a generic Cloud data migration methodology that includes all mentioned scenarios. Next to relational database management systems this methodology also supports NoSQL data stores, BLOB stores and content delivery networks. Using the generic methodology a Cloud data migration tool was developed which supports the decision process of selecting a Cloud data store and helps refactoring the application architecture by suggesting Cloud data patterns and potential adaptions of the network, data access and application layer. Finally the migration tool is able to copy data from a source system like MySQL server to a target system like Amazon RDS (MySQL, SQL Server, and Oracle), Azure SQL Database and Amazon SimpleDB.
