Regional Deployment and Disaster Recovery Architecture for Customer Workloads
Defined and deployed a more resilient AWS architecture for customer-facing services that needed clearer recovery patterns, stronger release discipline, and better operational separation across environments.
Technical Implementation
- Defined a primary-region and warm-standby recovery model in Terraform so networking, compute, database, and DNS resources could be reproduced in both regions from the same source rather than maintained as separate manual stacks.
- Mapped application dependencies across ECS and Kubernetes workloads, ALB listeners, background jobs, and stateful services so failover order matched the actual runtime topology instead of a simplified infrastructure diagram.
- Implemented Route 53 health checks and failover records, ALB target group routing, RDS backup and replica patterns, and S3 replication where required so the recovery path was built into the architecture rather than left as an operational note.
- Validated the design through GitLab CI release gates, Terraform plan review, CloudWatch alarm checks, and tabletop failover drills that stepped through DNS changes, application startup order, and data-layer recovery actions with the client team.
Client Delivery & Handover
The project was run with both application and infrastructure teams so recovery design, release validation, and support expectations were agreed during implementation. Operational walkthroughs and tabletop-style sessions were used to test understanding of the deployment and failover model before handover. Deliverables included recovery diagrams, deployment standards, runbooks, environment documentation, and guidance for future resilience testing so the client could maintain and rehearse the design after the engagement.
Outcome
The result was a more deliberate deployment architecture, improved resilience planning, and a clearer operating model for handling high-impact production changes.
