Cloud Infrastructure Overhaul
High-scale distributed systems migration with zero downtime and automated CI/CD resilience.
Project Description
Enterprise Cloud Migration
Operating across 14 geographical regions, the client's legacy on-premises architecture experienced severe throughput degradations during seasonal demand spikes, resulting in escalating operational support overhead and delayed feature releases.
Citi Solution architected and executed a zero-downtime migration to a hybrid AWS and Azure containerized mesh. Using declarative Terraform blueprints and automated Kubernetes autoscaling, the infrastructure decouples transactional nodes while establishing multi-cloud redundancy.
The modernized architecture achieved a verified 99.99% service level availability, eliminating deployment downtime entirely through automated canary rollback pipelines and end-to-end SOC2 compliance telemetry.
