OpenCloud: Value-Add CloudBringing Openness and Innovation to

Network and Cloud Infrastructure

• Directly Take on the OTT Cloud Providers– Great long-term goal, but they have a 10-year head start– Risk that you are always playing catch-up

• Apply Cloud Technology to the Central Office – Great first step, but too modest as a long-term goal– Risk that narrow use case doesn’t pay long-term dividends

Answer Build a Value-Added Carrier Cloud– Treat OTT providers as commodity– Gain near-term CAPEX/OPEX savings

What Is Your Cloud Strategy?

Take on OTT Providers

It’s about services, not just infrastructureAmazon is able to leverage a rich service ecosystem

Still managing (virtual) servers; may improve CAPEX but not OPEXMisses opportunity to innovate around network-wide services

• Treat OTT Cloud Providers as Commodity• Treat Central Office as an Extension of the Cloud• Leverage Strategic Infrastructure to Build a Value-

Added Cloud that providers better…– Responsiveness– Bandwidth– Privacy– Trust– Predictability– Customization

What Should Be Your Cloud Strategy?

• Organizing Principle– Everything-as-a-Service (XaaS)– Service Composition & Custom PaaS

• Open Source Software– XaaS Operating System (XOS)– Network Hypervisor (OpenVirteX)– Global Install Cloud (OpenStack-as-a-Service)

• Operational Deployment– 5 “Data Centers”– 12 Internet2 Routing Centers– 100+ Edge Sites (Regional and Campus Networks)– Includes Access to EC2 and Commodity Services

• Defines Service as a first class object– Service = {Slice,…} + Controller-Plugin

• Flexible control over operational parameters– Isolation: Slice = {VM,…} + {VN,…}

• VM = Placement + Image + Resources (e.g., cores)• VN = Topology + NetOS + Resources (e.g., bandwidth)

– Composition: VN1 | VN2 | VN3

• Programming environment for orchestration – Specify Service Composition Policy– Create Custom PaaS– Monitor & Manage Service Scaling
