On Selecting the Right Optimizations for Virtual Machine Migration
Senthil Nathan, Umesh Bellur, Purushottam Kulkarni · 2016
To reduce the migration time of a virtual machine and network traffic generated during migration, existing works have proposed a number of optimizations to pre-copy live migration. These optimizations are delta compression, page skip, deduplication, and data compression. The cost-benefit analysis of these optimizations may preclude the use of certain optimizations in specific scenarios. However, no study has compared the performance & cost of these optimizations, and identified the impact of application behaviour on performance gain. Hence, it is not clear for a given migration scenario and an application, what is the best optimization that one must employ?
