Design and Implementation of a Data-Auditing Mechanism for Container Migration

Virtualization technology has become indispensable in edge computing environments where applications are deployed to many nodes. In the past few years, the technology has improved dramatically, and is not only used in the field, but is also the subject of much research. In particular, containers which are lighter in weight than virtual machines, have greatly expanded their market share in recent years. The problem is the migration of containers. Migration is the process of creating a container checkpoint image and moving the image so the container can be restored at a different location while maintaining its state. While migration is very easy to perform, it may also violate company regulations and/or national laws, depending on the destination. Therefore, we propose and implement a data-auditing mechanism for containers, which has been used for virtual machines. We evaluate the feasibility of the proposed mechanism.
