Improving Virtual Machine I/O Performance in Cloud Environments via I/O Functionality Offloading
… A key technology that drives cloud computing is virtualization. In addition to enabling multi-tenancy in cloud environments, virtualizing hosts in the cloud environments has made management of hardware resources increasingly flexible. An important consequence of virtualizing hosts in the cloud is …

VM2Docker : automating the conversion from virtual machine to docker container
… containers are a viable alternative to virtual machines because many applications do not require isolated kernels. Containers share the kernel with the host, as opposed to virtual machines which have a completely isolated kernel. Because of this distinction, containers are more …
