Abstract
This paper presents results of the ongoing
development of the Open Cloud eXchange (OCX) that has been
proposed in the framework of the GN3plus project. Its aim is to
provide cloud aware network infrastructure to power and
support modern data intensive research at European
universities and research organisations. The paper describes the
OCX concept, architecture, design and implementation options.
OCX includes 3 major components: distributed L0-L2
(optionally L3) network infrastructure that includes OCX
points of presence (OCXP) interconnected with GEANT
backbone; the Trusted Third Party (TTP) for building dynamic
trust federations; and the marketplace to enable publishing and
discovery of cloud services. OCX intends to be neutral to actual
cloud services provisioning and limits its services to Layer 0
through Layer 2 in order to remain transparent to current cloud
services model. The recent developments include an
architectural update, API definition, integration with higherlevel applications and workflow control, signaling and
intercloud topology modelling and visualization. The paper
reports about results and experiences learnt from the recent
OCX demonstrations at the SC14 Exhibition in November 2014
that demonstrated the benefits of an OCX enabled Intercloud
infrastructure for running data intensive real-time cloud
applications on top of the advanced GEANT multi-gigabit
network. The implemented OCX functionality allowed
applications to control the network path for data transfer and
service delivery connectivity between multiple Cloud Service
Providers (CSPs). It was used in combination with a multi-cloud
workflow management and planning application (Vampire) that
enables data processing performance monitoring and migration
of VMs and processes to an alternative location based on
performance predictions.
