One of the primary reasons for the phenomenal interest today in cloud computing is that it abstracts technological complexity away from the end user. Innovative high-bandwidth, low-latency services are accessed from the cloud, without much worry about the hardware or software resources deployed locally.
For the operators of networks that underlie cloud computing, of course, the technological considerations are not small. Whether engineering a private cloud to be operated by an enterprise information technology (IT) staff for that enterprise’s users or a public cloud to be operated by a provider of managed services to business customers, one of the key decisions to be made is how to interconnect servers and storage within and among datacenters and create virtual machines.
