The Dream“Send it to the cloud!”• Recover to someone
else’s infrastructure• Only pay for what you
use, when you use it!

The Harsh Reality• Operational Impact
o Who will be providing the daily care and feeding of the DR solution?
• Consistencyo Configuration Drifto Does your IT staff need to now
make changes in 2 places for every move in production?
• Costso Is the solution a Ferrari? Ford?
Fiero?o What does it actually cost to
declare? Do you know?

The Challenge: Complexity
Lots of VMs… Lots of storage… Intricate WAN
topology…Physical appliances…Mainframes…Users need access to
input data…

Why listen to me?• Solutions Architect at TierPoint• I design managed DR and IaaS solutions every
day• I talk to all walks of IT, across many verticals
o People who have implemented their own solutionso What’s working? What’s not?o Where’s the mind share?

6 Common Blunders1. Picking a product or solution before defining
requirements fully2. Designing and pricing solutions before talking to
your internal stakeholders3. Designing for the “check-box” rather than
function4. Neglecting to test regularly5. Neglecting to test fail-back6. Settling for less because of past experiences

Boring….“I just spun up 10 AWS instances while you talked. I’m in the cloud already!”
• You feel like you’ve just made PROGRESS…
• …but how does it address your project’s Success Criteria?

What are your priorities?
How up to date must the data be? (RPO) How quickly must it be made available? (RTO) Can employees/clients access the data? How near or far must this be from [critical site] ? What operational overhead does this create for my
team? How does the cost of DR align with changes to
production? Is it predictable? Can I live with a subset of production running at
declaration time? Does DR need to have full performance capabilities of
production?

Solution Approach1. Easy Wins – native replication or clustering2. RTOs & RPOs3. VMs – what can be protected as a portable unit?4. Physicals
1. Are any pending virtualization?2. Does it support recovering into a VM?3. Does it require a matching physical system?
5. Networking1. What carriers are required?2. What does the data change rate look like?
6. “Where are the eyeballs?”1. Is workspace needed to ensure consistent data flow?
7. Security 1. What frameworks must be adhered to?

Summary1.Focus first on your Applications
and People2.Derive RTOs and RPOs 3.Collect your data4.Map requirements to
infrastructure and technologies to best fit those individual needs
