The objective of this session is to enable customers with any level of DR experience to gain actionable guidance to advance their business up the ladder of DR readiness. AWS enables fast disaster recovery of critical on-premises IT systems without incurring the complexity and expense of a second physical site. With 28 availability zones in 11 regions around the world and a broad set of services, AWS can deliver rapid recovery of on-premises IT infrastructure and data. During this session we will walk you through the ascending levels of DR options made possible with AWS and review the technologies and services that help deliver various DR capabilities, starting from cloud backups all the way up to hot site DR. We will also explore various DR architectures and the balance of recovery time and cost.

3. Terminology
Business Continuity
Business Continuity ensures an
organization's critical business functions
continue to operate or recover quickly
despite serious incidents.
Disaster Recovery
Disaster Recovery (DR) enables the
recovery or continuation of vital technology
infrastructure and systems following a
natural or human-induced disaster.
Recovery Point Objective Recovery Time Objective
RTO is a targeted duration of which a
business process must be restored after a
disaster or disruption.
RPO is the maximum targeted period in
which data might be lost from an IT
service due to a major incident.
6. History of DR
There have been many challenges for traditional DR for
enterprises
• Building and maintaining regional data centers
• Failed DR tests
• Not meeting RPO & RTO
• High technical debt
7. AWS compared to traditional disaster recovery
Conventional
• High cost to build disaster recovery
sites or data centers (CAPEX)
• High cost of storage, backup,
archival and retrieval tools, and
processes (OPEX)
• Difficult planning, procurement and
deployment
• Challenging to verify DR plans
• Single level of DR across the
organization
AWS
• Low cost upfront investment
(CAPEX)
• On-demand costs (OPEX)
• Consistent experience across AWS
environments
• Recovery automation
• Separate levels of DR per
application or business unit
