In this paper, the authors explain about virtual network embedding strategies within cloud infrastructure backbone networks. They will first of all summaries and define the main principles of cloud computing and its different supplied services. Cloud computing can be defined as the combination of three components: grid computing, cluster computing and virtualization. They will propose new cloud infrastructure architecture, named the Cloud Infrastructure using Virtualization within Data centers and Backbone (CIVDB), which makes use of virtualization in all the cloud's equipment (i.e. routers and data centers).
