Traditional disaster recovery (DR) has had a spotty record for enterprises. This session compares conventional approaches to DR to those using the AWS cloud and talks about the four ascending levels of AWS DR options and the benefits and tradeoffs among them. The session goes on to discuss backup and restore architectures both using partner products and solutions that assist in backup, recovery, DR, and continuity of operations (COOP).

- 3. Terminology Business Continuity Business Continuity ensures that 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 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.

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

Editor's Notes
- Briefly introduce some of the things we will do Grab attention with $1000 giveaway Describe how it will work with a partner engagement
- Not discussing BC, however we will discuss Disaster Recovery, which is part of BC BC is the business functions recovery model DR is the technology & infrastructure systems There will be more questions as we get into a panel discussion during the Q&A panel
- Tell the story of a friend, who is now the CEO of a mid-sized enterprise. who lost his entire office, data center and building in a fire, then after telling the story relate those terms in RPO and RTO. A small company with only a few employee’s at the time is now thousands strong There are many options and variations for setting up disaster recovery. Your business requirements like RPO and RTO drives a lot of this. Most of the DR scenarios depend on these two key metrics.
- If it harms critical business processes, it may be a disaster Time-based definition – how long can the business stand the pain? Think about the Probability of occurrence Fire, flood, hurricane, tornado, earthquake, volcanoes Plane crashes, vandalism, terrorism, riots, sabotage, loss of personnel, etc. Anything that diminishes or destroys normal data processing capabilities User Error / Corruption / Hacking Attack - Hacking – Thief Icon User initiated threat High Availability in the context of corrupt data. Systems corruption (systems corruption as in the systems stop functioning) U
- Discuss my past of designing and building out traditional DR/Data centers. The complexity that came from those scenarios. Lead into the next slide that shows the advantages of AWS Very manual process. Challenges with High Technical debt and runbooks for executing a DR
- Conventional vs AWS High upfront capex
- Multi-Region vs. Multi Data Center messaging / Geographic separation Mention data guard being used with RDS Compare AZ’s to DR data centers

- Discuss the application to be used throughout all the scenarios Open Source Software to be used for all layers Qualify upfront: Simple, Stateless application Backup and restore to on-prem or other location.
- Options include the AWS Storage Gateway and solutions from partners available from the AWS Marketplace
- Same application, Database replication is the key difference.
- Pilot Light architecture Note the addition of DirectConnect Costs for DirectConnect not included
- Consider augmenting this with existing technologies
- Lets looks at warm standby scenario The term warm standby is used to describe a DR scenario in which a scaled-down version of a fully functional environment is always up and running. A warm standby solution extends the pilot light as it decreases the overall recovery time Extremely low RTO/RPO Automation becomes a critical element as you ascend to this level of Disaster Recovery
- Multi-Site Running both sites at once Database replication going both directions Costs: Remember this doesn’t include direct connect costs.
- Warm standby and multisite are great options for low RTO/RPO’s
- 3rd – Do some in depth investigation on 3rd party vendors, they aren’t all a good fit for every use case Technical Debt – The cost’s don’t represent the level of technical debt Look to automate and opportunity to remove the technical debt. Technical debt as an opportunity to remove Customers are using DR as their entry point to DR
- We have many partners in this space that are ready to assist you with these challenges.
