3. WHAT IS DISASTER
RECOVERY?
It is the process of maintaining or reestablishing the
infrastructure following a natural or human-induced
disaster.

4. WHAT IS A DISASTER?
• NATURAL DISASTER (ex. FIRE, FLOOD, STORM,
EARTHQUAKE)
• DDOS ATTACK
• HUMAN ERROR
• SABOTAGE
• POWER OUTAGE
• EQUIPMENT FAILURE

5. TERMINOLOGIES
RPO (Recovery Time Objective)
• Maximum amount of time that can be lost after a recovery from a disaster.
• How far back?
• Acceptable Data Loss
RTO (Recovery Point Objective)
• Maximum acceptable time that an application, computer, network, or system
can be down after an unexpected disaster.
• How long to recover?
• Total Downtime

Go to EC2
* Create an AMI and copy it to DR Region
Go to RDS
* Take a snapshot and copy it to DR Region

ACTIVE/ACTIVE
• Traffic is load-shared between interfaces based on flow. If one connection becomes
unavailable, then all traffic is routed through the other connection..
ACTIVE/PASSIVE
• One connection handles traffic, and the other is on standby. If the active connection
becomes unavailable, then all traffic is routed through the passive connection.
DISASTER RECOVERY
OPTIONS

10. • Backup and Restore
• Deploy data, infrastructure, configuration and application code.
• Pilot Light
• Resources for data replication such as database and server storage are always on.
Other resources such as servers are “switched off” and are only used during a
disaster recovery.
• Warm Standby
• Infrastructure is scaled down but is fully functional. During a disaster, application is
scaled up.
• Multi-site / Active-Active
• Your workload simultaneously in multiple Regions.

ACTIVE

15. HOW CAN WE ACHIEVE THIS IN
AWS?
• Use Infrastructure As Code (IAC). Deploy the infrastructure with data pulled from replication.
• Use AWS BACKUP for data replication of database and server storage
• Use AWS Cloudendure / AWS Elastic Disaster Recovery
• Use AWS Route 53
• Design your DR with Multi Account or Multi Region

Go to DR Region, Singapore
Go to EC2, create ec2 from ami backup
Go to RDS, restore the database from snapshot
Get the Database Endpoint
Go to EC2, change the DB Endpoint to DR Database
