If the cloud-based infrastructure offers the live-migration capability, a virtualised service running on the cloud infrastructure is able to migrate from a server to another one with different hardware features at run-time without any issue in operations. With the increasing maturity of cloud-based infrastructures, the demand for highly available data-intensive applications is growing. To this end, the live-migration of virtualised services is an important characteristic of these solutions such as the PrEstoCloud on/offloading mechanism to cope with different problems for instance a single node failure or a situation when the system needs a bigger server to run tasks being carried out. It should be noted that such migrations are only applicable to PrEstoCloud for stateless fragments.
