Abstract
This disclosure describes systems, devices, and techniques for live migrating virtualized resources between the main region and edge locations. Live migration enables virtualized resources to remain operational during migration. Edge locations are typically separated from secure data centers via the Internet, a direct connection, or some other intermediate network. Accordingly, to place virtualized resources within an edge location, the virtualized resources must be migrated over a secure communication tunnel that can protect virtualized resource data during transmission over the intermediate network. The secure communication tunnel may have limited data throughput. To efficiently utilize resources of the secure communication tunnel, virtualized resource data may be transferred over the tunnel in a two-stage process. The disclosed technology provides various techniques for dynamically selecting which virtualized resource data, and how much virtualized resource data, is transferred over each of the pre-copy and post-copy stages.
