Session agenda• Context: on-premises disaster recovery (DR) using AWS

• Why AWS for recovery of on-premises IT infrastructure

• The ascending levels of DR

• DR/continuity scenarios

• Demo

• Q&A


TerminologyBusiness Continuity

Business continuity ensures that an organization's critical business functions continue to operate or recover quickly despite serious incidents.

Disaster RecoveryDisaster 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 ObjectiveRTO is a targeted duration in 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.

Plan for various types of disasters


History of DRThere 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


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
