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

Strategic Outsourcing

Cloud, XaaSVirtualization,

Big Data etc

Acquisitions & Mergers,

Approaches Translation

Tunneling

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

Deliver

IPv6 organization wide phenomenon, requiring a Holistic approach

IPv6 Phenomenon – A Holistic Approach

Deliver

to the

businessIPv6 program scope touches every aspect of IT and Business environment

Holistic Approach –Sample Enterprise Landscape

�� Networking Environment ��

�� Hosting Environment ��

Client/End User Environment

Routers/Switches

Storage Servers

Holistic Approach –Sample N-Tier Architecture

Holistic Approach: How and Where do I start?

Create IPv6 Enterprise business

case strategically

Create a holistic, coordinated, agreed-upon IPv6 Enterprise

Design IPv6 enterprise

addressing schema

Enterprise business case strategically

aligned with IT and business goals

coordinated, agreed-upon IPv6 Enterprise

roadmap and strategy

addressing schema completely

independent of IPv4

Holistic Approach: How and Where do I start?

Create Enterprise procurement

policy to Create Enterprise IPv6 risk/security

Create IPv6 program risk profile and

policy to mandate IPv6 requirement

IPv6 risk/security policy

profile and opportunity

profiles

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)

IPv4 and IPv6

Coexistence

1. The Network Upgrade

�Add IPv6 capability to Network

�Implement DHCPv6 servers; Update

DNS servers to support IPv6 records

2. The Client/End User Devices Upgrade

�Add IPv6 capability to Client endpoints

3. The Hosting/Data Center Upgrade

�Add IPv6 capability to Servers and

Hosting

�Analyze/enable IPv6 for Applications

4. IPv4/IPv6 Co-existence

�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

� 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

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
