“Internalization”

“Although the hot site market is

‘inelastic’ there is a rapidly increasing

availability of internal hot site solutions

for certain types of customers depending

on their size, their needs and the

computer equipment that they use.”

U.S. District Court Judge Ellen Huvelle, describing the hot site market during Sungard Data Systems’

bid to acquire Comdisco Availability Services

Alternate Site Strategies

What is your main alternate site strategy?

Internal, 31.90%

Hot-Site Vendor, 49.14%

Reciprocal,

6.90%

None, 8.62%

Mobile Hot-Site,

3.45%

Are companies really

moving to internal

strategies?

Does the internal

strategy work?

Is there a specific

industry that does it

more than another?

Top 5 Reasons for Trend

5. Can’t Keep Up with Our Technology!

4. We’re Too Complex and Interdependent

3. You’re Going to Charge How Much for Technical Support and Floor Space?

2. No Control (all approaches have pitfalls)• First come, first serve

• Guaranteed access

#1 Reason for Internal

Recovery Time Objectives are shrinking…

…and there is enabling technology that

assists us in achieving recovery times!

#1 Reason Nobody Thinks Of

Companies won’t declare

disasters for almost

100% of the most

common causes of

interruptions!

They’re ONLY used for

natural disaster and

Business continuity strategies MUST address all aspects of IT infrastructure, from basic asset protection and replacement to ensuring application continuity for internal operations and third parties.

HOT SITE SOLUTIONS

Hot Site Solutions DO have a place, but DO NOT apply them to the wrong business problem (e.g. recovery objective).

Considerations

Determine what recovery of full compliment

would cost with a commercial hot-site provider.

Do they have all the equipment in one spot?

What is the most important thing for commercial

hot site providers?

• People

• Test Time - Do you ever get it when you want it?

• Floor Space, how much does it cost?

When is Internal Obvious? Do you have two or more data

centers?

Are they within 300 miles of each other?

Do you have space available (growth projections)?

Do at least two of your applications require recovery in less than 12 hours?

Do you have a robust wide-area network?

Do you have significant excess capacity for testing and development of applications?

Compare the Costs

Must pay for perceived “low-

value” items like cabinets

and floor space.

Extra test-time costs money

and is difficult to schedule.

Acquired new technology and reallocated servers (from test & development).

Having more flexibility for testing SHOULD increase the ease and # of tests.

Increase in network is required.

Work area Recovery is still required; however, other offices could be leveraged.

Debunking Myths

Pulling attention away from “core competencies”.

Why would you want to create “business continuity experts”?

Pace of change in IT – can’t refresh!

You need multiple copies of data.

Allow the strategies to evolve, it DOES NOT have to be all or nothing. Review criticality and then

implement the appropriate solution!

Conclusion

It does make sense sometimes!

Don’t be emotional, but logical about decision.

People, procedures, data and network should be

the same for either method.

Evolution – implement solutions slowly while still

covered by hot site.

Use the resources available to you.
