Deploying a Disaster Recovery Site
on AWS
Minimal Cost with Maximum Efficiency

What do I expect you to know?
• 300-level talk
• Have some prior experience with AWS
• Understand/know basic terms, like Amazon EBS, Amazon S3, and
Amazon EC2
"I get it and want to learn more."
• Sessions will dive deeper into the topic. Presenters assume the
audience is familiar with the topic but may or may not have direct
experience implementing a similar solution. Code may be shared but
will not be the primary focus of the session.

We are historians
…even if you don’t know it.

"Shut up, shut up! I am
busy…”
- Jack Phillips, RMS Titanic telegraph operator

Disaster
Recovery point
Data loss

"SOS, SOS,CQD,CQD
MGY. We are sinking
fast - passengers are
being put into boats..
MGY”
- Titanic last radio call

Down time

Lessons learned?
Failure is not one thing…

Disaster recovery as
an event
aka watch this...

Ability to recover when
you’re mobile.

Lessons from history
Plan for more than just what
you expect to happen.

Test your execution plan
before you think you can
implement it.

Knowledge is critical. Know
how to interpret an alarm on
events.

“Alexa, fail over my data center”
#Alexafailover

Remember to complete
your evaluations!
