Enterprise wide program: Drivers


Business Drivers: IPv4 Exhaustion

Global demand for IPv4: RIR IPv4 Exhaustion:


Regional Internet Registry (RIR)


However…. IPv6 Still very young!

• Worldwide Adoption rate still < 1% but GROWING!

External Drivers – Industry Trends

National IPv6 Strategies

Growth, expansion, &
Infrastructure Evolution

Globalization and
Consumerization

2015: 17% of Internet will use
IPv6, with 28% of new Internet
users running protocol (Gartner):


Internal Drivers

Cloud, XaaS
Strategic
Virtualization,
Outsourcing
Big Data etc

Acquisitions
Ever greening
& Mergers,
(Asset
Joint Ventures
refresh)
etc

Adoption Methods
“One size does not fit all”
Core to Edge (Inside Out or Bottoms Up): “I can wait for end-to-end”
Least regret cost
Edge to Core: “I need something now to connect IPv6 users
Requires translation
“Translation akin to a drug addiction – easy to get in, difficult to
leave”
Internet Edge – AKA “thin edge” – Business continuity only
Note: Thin Edge IPv6 access method shows highest observed
growth


IPv6 Phenomenon – A Holistic Approach

IPv6 organization wide
phenomenon, requiring a
Holistic approach
Deliver
to the
IPv6 program scope touches
business
every aspect of IT and Business
environment


Holistic Approach –Sample Enterprise Landscape
Networking Environment

Client/End User Environment

Hosting Environment

Routers/Switches

Storage Servers


Holistic Approach –Sample N-Tier Architecture


Holistic Approach: How and Where do I start?

Design IPv6
Create IPv6 Create a holistic,
enterprise
Enterprise business coordinated, agreed-
addressing schema
case strategically upon IPv6 Enterprise
completely
aligned with IT and roadmap and
independent of IPv4
business goals strategy


Holistic Approach: How and Where do I start?

Create Enterprise Create IPv6
procurement Create Enterprise program risk
policy to IPv6 risk/security profile and
mandate IPv6 policy opportunity
requirement profiles


IPv6Enterprise Example: Dual Stack, Core to Edge

IPv4 Network – What we use TODAY

Typical landscape Today: ALL IPv4


Dual-Stack Step 1: Network Upgrade

Step 1: Dual Stack Network environment

i.e. routers, DNS, DHCP, Firewalls etc.

Application Processing (servers/clients)
remain IPv4


Dual-Stack Step 2: Clients/End-Users Upgrade

Step 2: Dual Stack
Client environment


Dual-Stack Step 3: Hosting & Storage Upgrade

Step 3: Dual Stack Data
Center/Servers & Storage


Fully Dual-Stacked, IPv6 Ready (IPv4 Compatible)

FMO: Dual Stack IPv4 and IPv6

Sample Multi-Phase Deployment Approach

Year X .... Year Y .... ....Year Z
IPv4 and IPv6
Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Coexistence

Network Upgrade Client Upgrade Server & Application Upgrade

1. The Network Upgrade 3. The Hosting/Data Center Upgrade
Add IPv6 capability to Network Add IPv6 capability to Servers and
Implement DHCPv6 servers; Update Hosting
DNS servers to support IPv6 records Analyze/enable IPv6 for Applications

2. The Client/End User Devices Upgrade 4. IPv4/IPv6 Co-existence
Add IPv6 capability to Client endpoints Plan for phasing out IPv4


Holistic Approach: Cost Benefits

Overall cost of IPv6 program should be shared
by various Lines of Business and IT
departments.

A holistic approach achieves cost benefits via
Ever greening (Business As Usual) VS project
costs.

Enterprise budget s may vary, Gartner
estimates cost of migrating an enterprise to
IPv6 could be as high as six per cent of the
entire annual IT budget.

Moreover, Once migration is complete, the
ongoing costs will fall to about one per cent of
the IT budget

IPv6 - ROI : A “Relative Term”

IPv6 program ROI can be measured in several ways:
Elimination of
Overhead and maintenance costs associated with
complex IPv4 network (Think: Network Address
Translation)
Gartner estimates, once migration is complete,
ongoing costs (Operations)will fall to about one
per cent of IT budget


IPv6 - ROI: It is for REAL
Ground floor for designing next generation roadmap
for entire organization for next century and beyond.
If we do it right, we already have a ROI, If we don’t,
we’ll have a “Negative ROI”
Think Tank: What is the ROI that a CXO can put on
an organization’s next 50-100 years of future
ROI in terms of competitive advantages gained for an
Enterprise to stay nimble, agile, productive, and
ready for the next growth opportunity
Analogy: ROI by investing in IPv6 program today
is similar to returns achieved via compounded
Interest when started at an early age


ROI Theory - Longer term Cost Savings


Conclusion
IPv6 migration is an organizational wide challenge
due to complexity and scale
IPv6 is networking industry's plan of record. There is
no alternative plan
IPv6 is “NOT” just a Network Initiative. Create a
holistic, coordinated, agreed-upon enterprise wide
IPv6 roadmap
Cost of implementing IPv6 is very small when make it
part of general IT roadmap. Aim to avoid any Y2K like
scenario
There is no flag day but world is not waiting
IPv6 is a Business Continuity Issue, that requires a
Holistic approach. Time to Strategically invest in IPv6
is NOW
