2015年10月26日（月）に開催した「Cisco OpenStack Private Seminar」の資料です。

1. OpenStack as a Strategy for
Future Growth
Lew Tucker, VP/CTO Cloud Computing
Cisco Systems, Inc.
@lewtucker

2. Entire Industries are being disrupted by
waves of innovation
Internet and Cloud Computing

3. Cloud computing brought in multi-tenancy and larger scale
- changing the fundamental economics
Public Cloud Computing

4. It’s a new world.
More virtual machines than physical hosts.
Physical Domain Virtual Domain
Instant, self-provisioning, dynamic allocation of resources

5. • Agility
• Faster Time to Market
• Lower Cost
• Automation through software
• Open Systems de-risk investment
• Mitigate vendor-lockin
• Services that span both public and
private deployments
Age of Software Defined Data Centers….

6. Cisco participated in the first
OpenStack Design Summit
that took place in Austin, TX
Joined the OpenStack
community officially in
February 2011

14. Software also disrupted traditional networking
- Software Defined Networking (SDN)
NFV VNFOpenFlow

15. Configuration and Cabling Becomes Code
Templates and declarative models replace manual procedures
submodule execd-routes {
import inet-types { prefix inet; }
include execd-types;
description
“providesfor configuring static routes
(IPv4 and IPv6).
grouping routes {
container inet {
list route {
key "name prefix-length";
leaf name {
type inet:ipv4-address;
}
leaf prefix-length {
type prefixLengthIPv4;
}
leaf enabled {
type boolean;
default true;
}

16. Software-driven Infrastructure based on
Policy rather than manual configuration
Congress: Policy as a ServiceGroup-based Policy
API’s
OpFlex: Policy Protocol

17. Hardware based networking service appliances being
replaced by Network Functions Virtualization (NFV)

21. Virtualized Media Workflows on OpenStack
Each of the functions in the media pipeline
is implemented as a (distributed) software
centric application
Collection of Application Containers
interconnected using a workflow becomes a
service container
The Workflow guides the flow of content
through the Application Containers and the
associated processing of data

23. • Need to re-think application and service design
based on composition of a set of simple, cloud based,
micro-services.
• Services need end-to-end orchestration across data
centers for best user experience.
• Web scale and continuous deployment is simply a
fact of life
• Continuous learning is the only way forward
Cloud Computing and Open Source are changing
how services are developed and delivered
