IaaS Migration Using the FELIX Federated Testbed

The ability to migrate services to a remote data center is an important feature of Cloud services, especially after a natural disaster. The FELIX project has developed a global scale testbed by federating multiple, distributed, data centers, called SDN islands. FELIX leverages on a transit network resource manager (TN RM) to enable NSI and GRE connections between different SDN islands. In this study, we perform an IaaS migration over the EU-Japan FELIX federated testbed and NSI-enabled network. The experimental results show that IaaS migration in a low latency environment performs high-speed migration, while in a high latency environment, communication optimization achieves a reasonable 10-minute IaaS migration.
