Run the Cloud FinOps DiagnosticThe Challenge
DotPe, a leading Indian fintech and retail-tech platform, was processing growing transaction volumes on infrastructure that wasn't keeping pace. PCI-DSS, SOC2, and ISO 27001 compliance demanded encryption, granular IAM controls, and full audit readiness, none of which were fully in place. A complex AWS-to-GCP migration needed to be executed with zero downtime, while manual deployment processes were creating security exposure and delaying the product roadmap.
Our Solution
GYSP executed a zero-downtime AWS-to-GCP migration, transitioning workloads to GKE using IaC-driven Terraform deployments for consistency and repeatability. Microservices were Dockerized across AWS EKS and GCP GKE. Secure CI/CD pipelines with integrated security scanning eliminated manual handoffs. Cloud Armor was implemented for DDoS protection, KMS for encryption, and automated ETL pipelines via AWS DMS enabled secure data warehouse transfers. Real-time threat response playbooks were built to achieve 100% compliance readiness across all three certification frameworks.

Frequently Asked Questions
How did GYSP execute a zero-downtime AWS-to-GCP migration for DotPe?+
GYSP used a progressive migration approach, standing up the GCP environment with Terraform IaC while AWS remained live, then migrating workload by workload using Blue/Green deployment strategies. AWS DMS handled data replication with minimal lag during the cut-window. Traffic was switched at the DNS level only after each component was fully validated in GCP, with instant rollback paths available throughout.
What is Google Cloud Armor and how does it protect fintech platforms?+
Google Cloud Armor is a managed DDoS protection and web application firewall (WAF) service sitting in front of GCP load balancers. It filters malicious traffic before it reaches the application, applies rate limiting, and enforces WAF rules against OWASP Top 10 threats. For DotPe, processing growing transaction volumes, Cloud Armor provided the first line of defence against volumetric and application-layer attacks without adding application-side latency.
How did GYSP achieve PCI-DSS, SOC2, and ISO 27001 compliance simultaneously for a fintech?+
GYSP built compliance into the infrastructure from day one. KMS encryption was applied to all data at rest and in transit, IAM controls enforced least-privilege access, and audit logging was enabled across all GCP services. Real-time threat response playbooks defined the incident management process required by all three frameworks. Automated reporting meant audit evidence was continuously generated rather than manually assembled at audit time.
What is AWS DMS and how was it used for DotPe's data migration?+
AWS Database Migration Service (DMS) is a managed service that replicates data between source and target databases with minimal downtime. GYSP used DMS to continuously replicate DotPe's transactional data from the AWS source to the GCP target during the migration window, ensuring the new data warehouse was fully populated and in sync before the application-layer cutover, with no data loss during the transition.
