Abstract

   Cloud services are revolutionizing the way computational resources
   are provided, but at the expense of requiring an even more
   revolutionary overhaul of the networking infrastructure needed to
   deliver them.  Much recent work has focused on intra- and inter-
   datacenter connectivity requirements and architectures, while the
   "access segment" connecting the cloud services user to the datacenter
   still needs to be addressed.  In this draft we consider tighter
   integration between the network and the datacenter, in order to
   improve end-to-end Quality of Experience, while minimizing both
   networking and computational resource costs.

1.  Introduction

   Cloud services replace computational power and storage resources
   traditionally located under the user's table or on the user's in-
   house servers, with resources located in remote datacenters.  The
   cloud resources may be raw computing power and storage
   (Infrastructure as a Service - IaaS), or computer systems along with
   supported operating systems and tools (Platform as a Service - PaaS),
   or even fully developed applications (Software as a Service - SaaS).
   Processing power required for the operation of network devices can
   also be provided (e.g., Routing as a Service - RaaS).  The inter- and
   intra-datacenter networking architectures needed to support cloud
   services are described in [I-D.bitar-datacenter-vpn-applicability].

   The advantages of cloud services over conventional IT services
   include elasticity (the ability to increase or decrease resources on
