  5. 5. Network/Security • Network bandwidth: 5 Gbps • Global company: VPN Site to Site
  6. 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. 7. Current Architecture
  8. 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. 9. First solution • What are the problems?
