ItemĪ custom image resides within the same region as the snapshot from which the image was created. Create a custom image on the Snapshots pageīefore you create custom images from snapshots, take note of the items described in the following table.Create a custom image on the Instances page.Create a custom image on the Images page.The memory overhead on that chain is also reduced by 15x.You can use one of the following methods to create a custom image from a snapshot:

Throughput of RocksDB by about 48% compared to vanilla Qemu on a snapshot chain Prototype, called sQemu, demonstrating that it brings significant performanceĮnhancements and memory footprint reduction. Our fourth contribution is the thorough evaluation of our The Qcow2 format and its driver in Qemu to address the identified scalabilityĬhallenges. Our third contribution is the extension of Show that long chains lead to performance and memory footprint scalability It reveals the presence of long snapshotĬhains, sometimes composed of up to 1000 files.

Ourįirst contribution is the characterization of disk utilization in a public In this paper, we make four contributions. Virtualization is efficiently achieved through direct access, disk
