1 Open Cloud exchange (OCX) Draft Proposal and Progress GN3plus JRA1 Task 2 - Network Architectures for Cloud Services Yuri Demchenko SNE Group, University of Amsterdam 10 October 2013, GN3plus Symposium, Vienna

2 Outline GN3+ JRA1: Network Architectures for Horizon 2020 General use cases and scenarios for Cloud services delivery to NRENs and universities Cloud and Intercloud Infrastructure and Services Open Cloud exchange (OCX) Requirements to OCX OCX design principles and suggestions Pilot implementation by SURFnet GreenQloud and OneXS Topics for discussion Additional information Intercloud Architecture Framework (ICAF) and Intercloud Federation Framework (ICFF) GN3Plus Symposium Open Cloud exchange (OCX) Slide_2

3 JRA1: Network Architectures for Horizon 2020 Task 0: Activity Leadership Task 1: Future Network Architectures Task 2: Network Architectures for Cloud Services Task 3: Network Architecture for Aggregating High- Speed Mobile Networking GN3Plus Symposium Open Cloud exchange (OCX) 3

4 JRA1 Goals and Tasks Network Access and Delivery Network Infrastructure (NADI) plays important role in delivering cloud services to campuses and research organisations and includes 3 parts/layers The user access network, which connects users to applications. Extreme high-speed networks, which interconnect physical servers and the movement of their virtual machines (VMs). Mega pipe networks, interconnecting storage tiers. JRA1 Task2 and Task 1 will investigate and propose the best architecture for practical NADI implementation To support cloud-based services, including the distribution of very large scientific data Pilot implementation and demonstration of few use cases JRA1 and JRA2 will cooperate on multiple topics Network virtualisation and automation to deliver Performance on Demand by automating the allocation of shared network resources among data centres on behalf of cloud operations JRA1 s focus on the network elements to support cloud-based services interconnection and integration, with focus on the southbound elements of the management and related control plane when interworking with the software-driven network elements JRA2 will research true software-driven networking for cloud-based services, with automated resource orchestration and provisioning that yield reduced network capacity requirements, predictable service performance, and simpler operations GN3Plus Symposium Open Cloud exchange (OCX) 4

5 Use Cases for delivering Cloud services to campus based users Scientific application and scientific data LHC/HEP, genomics, astronomy, climate, video, etc. (+long tail science) Streaming high-speed high volume experimental data to labs in campus location Direct links through campus network Distributed (Big) Scientific processing with MPP tools on distributed facilities distributed between few locations next to local datacenters CSP and campus L0-L2 (L3) network peering Dark fiber with termination as campus network or as CSP network VoIP SURFnet approach with mobile data access Support mobile access network (LTE) and tunnel access to campus network GN3Plus Symposium Open Cloud exchange (OCX) 5
