Description

This curriculum spans the technical, organisational, and financial dimensions of cloud-based disaster recovery, comparable in scope to a multi-workshop operational resilience program that integrates architecture design, cross-functional coordination, and ongoing governance across business units and cloud environments.

Module 1: Assessing Business Impact and Defining Recovery Objectives

Conduct stakeholder interviews across finance, operations, and IT to quantify acceptable downtime for critical applications in terms of revenue loss per hour.
Negotiate RTOs (Recovery Time Objectives) and RPOs (Recovery Point Objectives) with business unit leaders for tier-1 systems, balancing technical feasibility with operational constraints.
Map application dependencies using network flow analysis to identify hidden interdependencies that could delay recovery.
Classify workloads into recovery tiers based on regulatory exposure, customer impact, and support SLAs.
Document data gravity implications when replicating large datasets across regions, factoring in egress costs and transfer duration.
Establish criteria for declaring a disaster, including thresholds for system unavailability and communication protocols with executive leadership.

Module 2: Cloud Provider Selection and Multi-Cloud Strategy

Evaluate regional availability and service maturity across AWS, Azure, and GCP to determine alignment with required recovery geographies.
Compare native replication capabilities of object storage services (e.g., S3 Cross-Region Replication vs. Azure Geo-Redundant Storage) for durability and activation latency.
Assess contractual obligations around data sovereignty when replicating workloads across national boundaries.
Design failover pathways between primary and secondary clouds, including DNS cutover mechanisms and identity federation continuity.
Negotiate enterprise support agreements that include guaranteed response times during declared disaster events.
Implement consistent tagging and resource naming conventions across providers to enable automated recovery orchestration.

Module 3: Architecting Resilient Infrastructure

Deploy stateless application tiers across multiple availability zones using auto-scaling groups with health check integration.
Configure database replication (e.g., PostgreSQL logical replication or SQL Server Always On) with automated promotion scripts for secondary region.
Implement immutable infrastructure patterns using infrastructure-as-code templates to ensure configuration consistency during rebuilds.
Design storage replication workflows for file shares and databases, including bandwidth throttling during peak business hours.
Integrate third-party monitoring tools to detect regional outages and trigger failover decision workflows.
Size secondary region compute capacity based on projected load during recovery, including surge demand from displaced users.

Module 4: Data Protection and Replication Management

Schedule incremental backups with application-consistent snapshots, coordinating with transaction freeze windows for databases.
Validate backup integrity through automated restore testing in isolated environments on a quarterly basis.
Manage encryption key replication across regions using cloud key management services with role-based access controls.
Implement retention policies aligned with legal hold requirements, including write-once-read-many (WORM) configurations.
Monitor replication lag for critical data streams and set alerts for deviations beyond RPO thresholds.
Optimize data transfer costs by scheduling bulk replication during off-peak hours and leveraging compression.

Module 5: Failover and Failback Orchestration

Develop runbooks that specify manual and automated steps for transitioning DNS, IP addressing, and load balancer configurations.
Test automated failover scripts in non-production environments, including rollback procedures for partial failures.
Coordinate identity provider failover to ensure uninterrupted authentication during recovery.
Validate application functionality post-failover by executing synthetic transactions across critical business paths.
Establish communication protocols with external vendors and partners who depend on recovered systems.
Define criteria for initiating failback, including data consistency checks and primary region stability validation.

Module 6: Testing and Validation Frameworks

Schedule annual full-scale disaster recovery drills with participation from operations, security, and business continuity teams.
Conduct quarterly tabletop exercises to validate decision-making chains and escalation procedures.
Measure actual RTO and RPO against targets and document root causes of deviations.
Use infrastructure-as-code to spin up isolated recovery environments for testing without impacting production.
Integrate recovery testing into change management processes to assess impact of configuration updates.
Document test outcomes and update recovery plans within 10 business days of exercise completion.

Module 7: Governance, Compliance, and Continuous Improvement

Align recovery controls with regulatory frameworks such as HIPAA, GDPR, or SOC 2, including audit trail retention.
Assign ownership of recovery plans to system stewards with accountability measured in performance reviews.
Integrate recovery metrics into enterprise risk dashboards for executive visibility.
Update documentation immediately following infrastructure changes, enforced through CI/CD pipeline gates.
Conduct post-mortem analyses after unplanned outages to refine recovery procedures.
Review third-party vendor recovery capabilities annually and track compliance through service organization controls reports.

Module 8: Cost Optimization and Resource Management

Right-size standby resources using reserved instances or sustained use discounts without compromising recovery capacity.
Implement auto-suspend policies for non-critical recovery environments during non-testing periods.
Compare cost of active-passive versus active-active architectures for mission-critical systems.
Track data transfer and storage expenses across regions to identify budget overruns early.
Use tagging and cost allocation tools to attribute recovery spending to business units.
Negotiate capacity reservations with cloud providers for priority access during regional outages.
