The Importance of High Availability
A PFMIS shutdown can halt the entire public administration, delaying civil service salaries, freezing supplier payments, and disrupting critical public utilities. To mitigate this risk, the system architecture must be designed for high availability and resilience.
Core Disaster Recovery Components
  • Primary Cloud Data Center: The active environment that hosts the live PFMIS application and databases.
  • Secondary Disaster Recovery (DR) Site: A geographically separated facility that mirrors the primary data center in real time. If a natural disaster, power outage, or cyberattack takes down the primary data center, operations automatically failover to the DR site.

Recovery Metrics and Backup Strategies
The Treasury establishes strict recovery benchmarks to guide technical teams:
[ Recovery Point Objective (RPO) ] ---> The maximum tolerable data loss window (e.g., under 15 minutes)
[ Recovery Time Objective (RTO) ] ----> The maximum acceptable duration of system downtime (e.g., under 2 hours)

Automated, incremental backups are encrypted and stored offsite daily to protect historical records against ransomware attacks or physical facility damage.
