Live Migration of Docker Containers through Logging and Replay
Chenying Yu, Fei Huan · 2015
The lightweight virtualization technique has made virtual machines more portable, work more efficient and easier to management.The time of live migration can be greatly reduce when applied to containers based on the lightweight virtualization technique, which is very beneficial to data centers.This paper presented a logging and replay approach for live migration of Docker containers.With this approach, both the down time and total migration time are reduced in the experiment.Compared with the approach for traditional virtual machines, the down time has reduced by 65%, 55% and 44% under three different scenarios, meanwhile the total migration time has reduced by 27%, 47% and 38% respectively
