Join Amazon Web Services for a webinar on how others are using the AWS Cloud to enable faster disaster recovery of their IT systems without incurring infrastructure expenses. Join us for an informative webinar on how AWS Cloud supports many popular disaster recovery (DR) architectures from “pilot light” environments that are ready to scale up at a moment’s notice to “hot standby” environments that enable rapid fail-over. With infrastructure centers in 10 regions around the world, AWS provides a set of cloud-based DR services that enable rapid recovery of your IT infrastructure and data.

5. AWS Global Infrastructure
10 Regions
consisting of
26 Availability Zones
and
51 Edge Locations (CDN)
Customer Decides Where Applications and Data Reside

6. AWS Region View
- Independent/Separate Geographic Areas
- Isolated from other Regions (security boundary)
- = ~50 mile radius “clustered” data center architecture
- Comprised of multiple Availability Zones
- Availability Zone = 1 or more “data center”
- Availability Zones connected through redundant low-
latency links
- Customer chooses a Region and Data stays within Region.
- Enables High-Availability Architecture

7. AWS Availability Zone (AZ) View
- Multiple Isolated locations within a Region
- Availability Zone = 1 or more “data center”
- Independent Failure Zone
- Physically separated
- On separate Low Risk Flood Plains
- Discrete UPS
- Onsite backup generation facilities
- Fed from different segments of utility provider
- Redundantly connected to multiple tier-1 ISP’s

11. Basics of Disaster
Recovery

12. DR is part of a wider set of policies and controls…
DR & business continuity
It’s not an all or nothing thing
Choose what needs to failover and what does not
Some things more important than others
Some things will still be working
High availability Backup Disaster recovery
Keep your applications
running 24x7
Make sure your data is protected
and can be recovered if it is lost
Get your applications and
data back after a major
disaster

13. Each set of IT assets will have different requirements…
DR & business continuity
Recovery Time Objective
(RTO)
How quickly you need this asset to be recovered?
e.g. 1min? 15min? 1hr? 4hrs? 1day?
Recovery Point Objective
(RPO)
How ‘fresh’ the recovery must be for the asset?
e.g. zero data loss, 15mins out of date?

14. Assets will sit on a spectrum of technical complexity…
DR & business continuity
Rebuild when
required from
offsite backup
Run hot-hot
configuration with
auto-failover

18. With utility services you might be able to:
Business & technical drivers
Reduce costs
Slash DR budgets by up to 50%
Reduce on-premise
Eliminate 30%+ of on-premise
physical equipment
Consolidate sites
Eliminate the need to run a
secondary site
Remove aging
technologies
Eliminate tape for backup and
archive

19. Challenges around Cost
Conventional DR Sites
High Cost
Low ROI
Implemented only for
most critical systems
Usually scaled down to
50% of production
Systems in a remote
region challenging

20. Cost Effective – On Demand Infrastructure
Disaster Recovery on AWS
Unprecedented
capabilities to implement
DR sites
Easily set up DR sites on
different geographic
regions
Cut down DR site cost by
up to 70%
Substantial savings on
software licenses
