Analysis of Cloud Bursting from the Openstack Infrastructure to AWS

Cloud bursting provides enterprises, especially those of small and medium scale, the ability to scale up their own infrastructure using the resource of an external cloud. However, many cloud bursting software are proprietary and strictly dependent on a specific cloud platform. Moreover, the technique remains difficult for its complexity and inconsistency in maintaining its performance especially during the production phase. In this paper, a cloud bursting technique for an Openstack environment to the AWS EC2 platform is conducted using the open-source OMNI module and the results are analyzed. We found that during the migration of many VM instances, the time to synchronize is heavily impacted in contrast to moving a small collection of VMs with larger sizes. It is also found that the utilization of adequate scheduling algorithms can be achieved to enhance the cloud bursting technique, better synchronization time, and lower delay between each separate migration.
