1. OpenCloud: Value-Add Cloud
Bringing Openness and Innovation to
Network and Cloud Infrastructure

2. What Is Your Cloud Strategy?
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

3. Take on OTT Providers It’s about services, not just infrastructure
Amazon is able to leverage a rich service ecosystem
Slide says Amazon, but similar experiences elsewhere (Google, Microsoft, Akamai).
Main point – our approach is based on experience.

4. Central Office as a Data Center
NFV Orchestration
NFV chaining
L2VPN/L3VPN/
L3 Connectivity
L2 Connectivity
Still managing (virtual) servers; may improve CAPEX but not OPEX
Misses opportunity to innovate around network-wide services

5. What Should Be Your Cloud Strategy?
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

6. OpenCloud – Pilot Value-Added Cloud
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

7. Scalable Function = Service Everything-is-a-Service (XaaS)

about best practices in scaling functionality
about treating the
network’s data plane
as a programmable function

Scalable Function = Service
Everything-is-a-Service (XaaS)

8. Anatomy of a Service Service Controller
Logically centralized interface
to network-wide functionality.
Service Controller
Network-as-a-Service
Compute-as-a-Service
Content Delivery Network
Many points of implementation
distributed across the network.
Service Instances
(VMs, Devices)
OpenFlow Switches
Virtual Machines
Caches

9. Service Composition Service3 = Service1  Service2 Service1 Service2
Logically compose services to achieve
desired functional/security behavior

Service2 VM VM VM VM VM VM VM VM VM VM VM
Map onto physical infrastructure to
meet performance requirements VM VM VM VM VM VM VM VM VM VM VM VM VM VM

13. XOS – XaaS Operating System
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
