*General Context*
Cloud services were originally deployed over the top, in particular over
the Internet. More recently companies are deploying their own private
cloud solutions and we see a need for portability and interoperability
of public and private clouds.
We expect that brokers will become key players in such future solutions.
Historically, telecom service providers were focused on supplying
connectivity based on the VPN concept. These services have evolved to
facilitate outsourcing of advanced functionality like routing and even
security (L3 IP VPNs, security as a service, etc.).
VPN service providers started to offer dynamic access trough VPNs to
their own cloud services and also to 3^rd party cloud services; e.g.,
the "VPN gallery service" of Orange Business Services. In the future,
such services will enable dynamic mapping of cloud services over
existing VPNs, hence allowing the VPN service provider to become a
broker of cloud-based infrastructure and services. Moreover, cloud
resources that are controlled by service providers will move out of
large datacenters to be located in various other points, including
telecom service providers, networking PoPs, and even customers locations
(e.g. in CPEs).
This requires a joint network/cloud architecture as well as global
optimization of resources. Indeed, the dynamism of cloud based services
cannot be really achieved without an associated dynamic control of
network resources.
Moreover, we foresee in the midterm a new generation of brokers that
will dynamically select from among various providers and orchestrate
both network and cloud services to answer dynamically specific client's
requirements.
*Topics of research *
The proposed research activity will focus on the following main topics:
1. Defining the overall joint network/cloud architecture so as to
enable the dynamic creation of enterprise services. Introducing the
concept of "broker" in the global architecture.
2. Design of the required resource optimization mechanisms, covering
jointly network and cloud resources.
3. Design of other optimization mechanisms, such as content location
over distributed clouds (as opposed to datacenter-based clouds).
4. Proposal and performance analysis of pricing models to clients and
business models among the players.
*Timeframe and Place(s)*
The extent of the position is for one year and may be extended for
additional 6 months. The research can be conducted at either
* Telecom ParisTech (Paris, France) and more specifically at the LINCS
(www.lincs.fr <http://www.lincs.fr>) a joint laboratory recently
created by INRIA, Institut Telecom, UPMC and Alcatel-Lucent Bell labs,
* The Department of Electrical Engineering, Technion (Haifa, Israel),
* RAD Data Communications (Tel-Aviv, Israel).
The candidate can share her/his research time among these sites as per
her/his preferences.
