The scalability of modern data centers has become a practical concern and has attracted
significant attention in recent years. In contrast to existing solutions that require changes in …

Data centers rely on virtualization to provide different services over a shared infrastructure.
The placement of the different services and tasks in the physical machines is crucial for the …

Today's data centers need efficient traffic management to improve resource utilization in
their networks. In this work, we study a joint tenant (eg, server or virtual machine) placement …

We study the problem of virtual machine (VM) placement and migration in a data center. In
the current approaches, VMs are assigned to physical servers using on-demand …

As tenants take networked virtual machines (VMs) as their requirements, effective placement
of VMs is needed to reduce the network cost in cloud data centers. The cost is one of the …

In this paper, we propose virtual data center (VDC) as the unit of resource allocation for
multiple tenants in the cloud. VDCs are more desirable than physical data centers because …

Steady state VM management in data centers should be network-aware so that VM
migrations do not degrade network performance of other flows in the network, and if …

In recent years, the power costs of cloud data centers have become a practical concern and
have attracted significant attention from both industry and academia. Most of the early works …

Improving energy efficiency of data centers has become increasingly important nowadays
due to the significant amounts of power needed to operate these centers. An important …

While virtual machine (VM) migration is allowing data centers to rebalance workloads across
physical machines, the promise of a maximally utilized infrastructure is yet to be realized …
