A novel concept for the migration of workloads using virtual machines that can mitigate limitations of traditional service deployment concepts

The project aims to investigate the outsourcing of cloud ser- vices to clients by including heterogeneous, client-side resources and co- operation between cloud and client in the execution of services. For this purpose, an offline-first strategy shall be formulated, developed, and in- vestigated to be used as a counterpart to the cloud-first strategy and enable the utilization of services without a permanent cloud connec- tion. The scope of the offline-first strategy is to achieve autonomy for applications while cooperating with cloud services. To achieve the inde- pendence and simultaneous cooperation of applications in this context, methods of service migration are to be researched to enable the provi- sion of services. In summary, this should increase resilience when using services, improve the stability of services along the cloud-to-edge supply, and allow transparent use for the end user. Furthermore, lab experiments were conducted to investigate the behavior of virtual machines during live migration in two setups, simulating a WAN link. The experiments show that migration over a WAN link takes five times longer for RAM- intensive tasks than in a LAN. This provides initial insights into selecting the technological basis for this project.
