Context & Pain Points
Legacy on-premises virtualization infrastructure suffered from scaling bottlenecks, single-points-of-failure, and lack of cross-account routing, stalling organizational business metrics.
What We Had To Solve
- Migrating critical production transaction state machines without halting day-to-day business operations.
- Interconnecting dozens of legacy VPCs with central security inspection zones cleanly.
- Establishing strict, identity-based resource policies and role boundaries for separate organizational teams.
How We Built It
- Used AWS Transit Gateway as a centralized network hub, routing traffic between virtual private clouds and on-premises data centers.
- Orchestrated database replication pipelines using Amazon RDS with automated backup snapshots and read replicas.
- Engineered comprehensive AWS Organizations structures with Service Control Policies (SCPs) to enforce hard boundaries.
Outcomes That Mattered
Zero Business Downtime
Performed cutover migrations of legacy transaction systems with absolutely zero service interruptions.
Centralized Transit Routing
Scaled network interconnections to over 30 isolated VPCs with zero routing loops.
40% Operational Savings
Pruned legacy datacenter hosting contracts in favor of right-sized, scalable AWS instances.
Outcome
Migrated core insurance ledger services to highly secure, multi-account AWS Organizations with cross-region disaster recovery, cutting operational overhead by 40% and boosting reliability.
