Demo: ThingsMigrate - Platform-Independent Live-Migration of JavaScript Processes

From Cloud to Edge: Seamless Software Migration at the Era of the Web of Things

“…This is confirmed by several experimental studies, including [33] that investigates the implementation of Docker-based virtualization mechanisms for IoT data management and demonstrates that the energy impact on single-board computers is negligible. An alternative to the usage of VM/containers is constituted by the migration of active code: to this purpose, the ThingMigrate framework [34] enables the migration of active JavaScript processes between different machines by employing injection mechanisms to track the local state of each function. With respect to the studies cited so far, the WT migration addressed in this paper can be considered a special instance of dynamic, agentbased [35] migration; at the same time, it presents novel opportunities as well as novel technical challenges which are discussed in detail in the Section below.…”

“…The M-WoT architecture does not depend on any specific software mobility technology. Instead, we have introduced an abstraction layer -called the Migration Substrate-which can employ any state-of-art solution (via proper migration connectors), such as Docker containers, VMs, or Javascript processes [5] [34]. Those connectors will actuate the Optimizer output plan received as input.…”
