Explore and learn about AWS with a ‘non-production’ use case Phase systems into ‘live’ DR use with reduced risk
Benefit from lower costs & only pay for what you use Gain the ability to test DR procedures more frequently
Invoke DR whilst testing DR procedures if necessary

Why AWS for Disaster Recovery?
![Page 6: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/6.jpg)
AWS is used in a variety of ways… AWS & Disaster Recovery
Fast, secure and cost effective backup and DR for Oracle Apps
“Using AWS has enabled us to move into a whole new market, while lowering our hosting
costs by 80 percent”
“Using AWS allowed us to implement a disaster recovery strategy at a fraction of the cost”

Galata benefits from increased DR scalability, flexibility and reduced
complexity
![Page 7: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/7.jpg)
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
![Page 8: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/8.jpg)
DR is part of a wider set of policies and controls… DR & business continuity
High availability Backup Disaster recovery
Keep your applications running 24x7
Make sure your data is safe
Get your applications and data back after a major
disaster
![Page 9: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/9.jpg)
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
![Page 10: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/10.jpg)
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?
![Page 11: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/11.jpg)
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

Archiving possibilities beyond tape using Glacier
![Page 26: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/26.jpg)
The preparation process… Backup & Restore pattern
Take backups of current systems
Store backups in S3
Move to long term archive in Glacier
![Page 27: AWS Journey through the AWS Cloud: Disaster Recovery](https://reader030.vdocument.in/reader030/viewer/2022021507/5874c3881a28ab8f508b5d43/html5/thumbnails/27.jpg)
