A fast-growing fintech platform was previously running its core transaction processing, application workloads, and supporting infrastructure on Google Cloud Platform (GCP). With increasing user growth and transaction volumes, the platform encountered scaling, cost, and compliance bottlenecks. Key challenges included:
- Complex Platform Migration: Transitioning critical containerized applications (Kubernetes), databases (PostgreSQL), and supporting infrastructure (Redis, RabbitMQ, Neo4j, etc.) from GCP to AWS while preserving performance, security, and service reliability.
- Scalability and Future-Proofing: Designing an AWS architecture to accommodate rapid business growth and variable traffic patterns, with auto-scaling support, high availability, and disaster recovery for financial workloads.
- Security, Compliance, and Regulatory Alignment: Establishing a robust security foundation in AWS to meet or exceed current GCP controls—covering encryption, network segmentation, access management, audit logging, and compliance for payment and banking integrations.
- Minimized Downtime and Business Disruption: Orchestrating a phased migration (infrastructure, database, application cutover) with comprehensive rollback options, extensive testing, and synchronized change windows to ensure service continuity for end-users, partners, and payment systems.
- Seamless Integration and Service Mapping: Accurately mapping GCP services (GKE, Cloud SQL, Memorystore, Pub/Sub, VPC, Cloud Storage, etc.) to AWS equivalents (EKS, RDS, ElastiCache, SQS, VPC, S3), and updating application endpoints/configurations for interoperability.
- Operational Excellence & Knowledge Transfer: Delivering extensive migration documentation, operational runbooks, post-migration support, and training for the platform's technical team to ensure sustainable day-to-day operations on AWS.
