In the event of a disaster, you need to be able to recover lost data quickly to ensure business continuity. For critical applications, keeping your time to recover and data loss to a minimum as well as optimizing your overall capital expense can be challenging. This session presents AWS features and services along with Disaster Recovery architectures that you can leverage when building highly available and disaster resilient applications. We will provide recommendations on how to improve your Disaster Recovery plan and discuss example scenarios showing how to recover from a disaster.

2. What do I expect you 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.

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

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

63. Lessons from history
Test your execution plan
before you think you can
implement it.

64. Lessons from history
Knowledge is critical. Know
how to interpret and alarm on
events.

65. So how easy can we make
this?
