3. General Introduction
• This is the core database and application for our
customer business data. It is critical to both
operational people and business analytical
researchers. The system is the source for
operational reports and analytical reports.

4. Hardware & Software
• 2 VMs: 32 cores, 100GB RAM
• OS: Redhat
• Storage: 2+ TB on disk array, 3000 IOPS, 50
MB/s.

5. Network/Security
• Network bandwidth: 5 Gbps
• Global company: VPN Site to Site

6. DR & HA
• RTO: 24 hours. Aim for 2 hours.
• RPO: 4 hours. Aim for 15 mins for future system.
• HA: 99.5% ~ 5 nights down time per year.
• Backup Retention:
– 3 days for 4 hours snapshots.
– 60 days for daily backups.

7. Current Architecture

8. Challenges
• RTO of 2 hours, RPO of 15 mins.
• No disk array on AWS  Have to deal with bit
rot, disk failures.
• Data growth 20% per year.
• Choose Oracle RDS or Oracle on EC2?
• Choose instance type that optimized for EBS.

9. First solution
• What are the
problems?

10. Our Solution
• How is this
solution better?

11. Cost Saving
• Instance type for instances: r3.4xlarge
– 10 Gbps
– 18000 IOPS for free
• Our solution: save 70% of AWS infrastructure
cost.
