Realizing an elastic memcached via cached data migration: poster

Abstract

Cloud computing has enabled economical resources, such as storage and VMs, that allow applications to be hosted online at low cost. The pay-as-you-go model in the cloud also enables elasticity. However, some stateful services like memory caches are not amenable to elasticity. Designing such services to be elastic requires careful consideration of the data saved on each VM while scaling in.
