Template Registry Engineering Standards

2. Executive Summary & Purpose

2.1 Purpose

This Standard Operating Procedure (SOP) provides an institutional-grade, repeatable framework for designing, executing, and maintaining an Information Technology Disaster Recovery Plan (ITDRP) aligned with Australian regulatory standards, including the Australian Prudential Regulation Authority (APRA) Prudential Standard CPS 234 and the Privacy Act 1988.

2.2 Objective

To guarantee business continuity, safeguard sensitive data residency (enforcing Australian data sovereignty requirements), minimize Recovery Time Objectives (RTO), and restrict Recovery Point Objectives (RPO) within acceptable organizational risk tolerances during an unforeseen infrastructure outage, cyber incident, or natural disaster.

3. Scope & Prerequisites

3.1 Scope

• In-Scope: All cloud-native production environments (AWS Sydney ap-southeast-2, Azure Australia East), on-premises hybrid assets, primary data repositories, identity providers (IdP), and supporting network fabrics managed by Template Registry.
• Out-Scope: Third-party SaaS application core infrastructure (managed under respective vendor SLAs, though integration endpoints are covered).

3.2 Required Tools & Software

• Terraform / OpenTofu (Infrastructure as Code)
• AWS CLI / Azure CLI (Administrative access)
• PagerDuty / Opsgenie (Incident notification platform)
• Enterprise Password Manager (Admin Vault Access)
• Isolated OOB (Out-of-Band) Communication Channels (e.g., Signal Enterprise, dedicated Slack workspace)

3.3 Prerequisites

• Active Multi-Factor Authentication (MFA) credentials for secondary region jump hosts.
• Validated cryptographic keys stored in AWS KMS / Azure Key Vault (replicated cross-region).
• Current personnel authorization verified against the corporate access control list (ACL).

5. Step-by-Step Procedure

Phase 1: Incident Assessment, Declaration & Activation

• 1.1 Verify telemetry alerts indicating a critical subsystem failure or region-wide outage in ap-southeast-2.
• 1.2 Convene the Disaster Recovery Committee via the out-of-band communication channel within 15 minutes of threshold breach.
• 1.3 Assess impact against predefined thresholds (RTO < 4 hours, RPO < 1 hour).
• 1.4 Formally declare an IT Disaster and issue executive authorization to initiate the ITDRP.
• 1.5 Trigger automated PagerDuty priority-1 broadcast to all engineering stakeholders.

Phase 2: Secondary Region Stand-Up & Infrastructure Provisioning

• 2.1 Authenticate into the designated secondary failover environment (e.g., AWS Melbourne ap-southeast-4 or Azure Australia Southeast).
• 2.2 Initialize the Infrastructure as Code (IaC) state repository for the failover target.
• 2.3 Execute terraform apply -target=module.core_networking to re-establish virtual private clouds (VPCs) and routing tables.
• 2.4 Deploy ephemeral compute clusters (Kubernetes / ECS) using verified base machine images (AMIs/VM Images).
• 2.5 Verify inter-region peering and firewall rule propagation.

Phase 3: Data Retrieval & State Synchronization

• 3.1 Mount secondary replication storage targets linked to the latest immutable, point-in-time storage snapshots.
• 3.2 Restore primary database clusters from cross-region encrypted snapshots (aws rds restore-db-instance-from-db-snapshot).
• 3.3 Run data integrity validation scripts (sha256sum cross-checks against pre-disaster manifest ledgers).
• 3.4 Confirm data residency compliance (verify no transactional data has traversed foreign jurisdictions, maintaining compliance with the Privacy Act 1988).
• 3.5 Execute database schema migration validators to ensure compatibility with active application binaries.

Phase 4: Traffic Cutover & DNS Re-routing

• 4.1 Update Route53 / Azure Traffic Manager latency-based routing policies to sink traffic away from the compromised primary region.
• 4.2 Adjust TTLs (Time to Live) to minimum thresholds (60 seconds) 24 hours prior to scheduled tests, or force immediate propagation during live incidents.
• 4.3 Redirect external API gateways and load balancers to the secondary region entry points.
• 4.4 Verify SSL/TLS certificate validity and binding on secondary termination points.

Phase 5: Functional Verification & Service Resumption

• 5.1 Execute automated end-to-end (E2E) smoke tests against core microservices.
• 5.2 Validate authentication flows via the identity provider (OAuth2 / OIDC token exchange).
• 5.3 Monitor error rates (5xx HTTP responses) and latency via APM dashboards (Datadog / New Relic).
• 5.4 Issue "All Clear" notice to internal stakeholders and transition operational control back to normal monitoring rosters.
• 5.5 Notify regulatory bodies (e.g., APRA, OAIC) if the incident meets mandatory notification criteria under Australian law.

6. Quality Assurance & Pro-Tips

6.1 Best Practices

• Immutable Backups: Ensure primary storage snapshots are write-once-read-many (WORM) protected to prevent ransomware propagation during a cyber-induced disaster.
• Immutable Code: Never modify IaC manually during an active disaster; force all changes through automated pipelines to prevent configuration drift.

6.2 Common Pitfalls to Avoid

• Failing to test DNS propagation delays: Assuming instant global cutover without accounting for cached DNS records at client ISPs.
• Ignoring regional quota limits: Ensure secondary regions have pre-approved service quotas (vCPU limits, IOPS allocations) with cloud providers to avoid deployment blocks during an emergency.

6.3 Metric Thresholds

• RTO Target: $\le 240$ minutes from declaration.
• RPO Target: $\le 60$ minutes of data loss.
• Data Sovereignty Metric: $100%$ compliance with Australian data storage boundaries.

7. Frequently Asked Questions (FAQ)

Q1: What happens if the secondary cloud region is also experiencing degraded performance? A: If a multi-region cloud provider outage occurs, the Disaster Recovery Director (DRD) is authorized to pivot execution to our cold-standby bare-metal facility located in Sydney, utilizing offsite encrypted cold storage media retrieved via secure courier protocol.

Q2: How do we handle compliance reporting to the Office of the Australian Information Commissioner (OAIC)? A: If the disaster involves a confirmed data breach or unauthorized access to personal information, the Data Protection Officer (DPO) must initiate the Notifiable Data Breaches (NDB) scheme protocol within 72 hours of discovery, independent of technical restoration tasks.

Q3: Are disaster recovery tests mandatory, and how often must they be run? A: Yes. Per APRA CPS 234 requirements, Template Registry must conduct end-to-end recovery simulations at least annually, with documented post-incident reviews submitted to the Board Risk Committee.
