💳 SP Transaction Hub — Cloud Storage Modernization Case Study

Executive Summary

Completed: July 2025
Timeline: 13 weeks
Team: 10 specialists
Financial technology and transaction processing

SP Transaction Hub, a rapidly growing fintech company, provides secure digital payment infrastructure — including UPI payments, merchant services, collections, payouts, and virtual accounts — to businesses across India.

To meet growing scalability and compliance demands, Zaptoz designed and implemented a secure, automated, and compliant AWS-based storage and backup solution.

The new architecture ensures encryption, lifecycle automation, cross-region backups, and centralized compliance monitoring — fully aligned with RBI and PCI-DSS standards.

This transformation reduced storage costs by over 45%, improved audit readiness, and achieved a recovery time (RTO) under 1 hour and recovery point (RPO) of 15 minutes, all while handling high transaction volumes with full data integrity.

Challenges

SP Transaction Hub faced several infrastructure and compliance challenges before modernization:

Security & Compliance Gaps:

Data lacked encryption at rest and in transit, with limited access control.

Manual Backups:

Backups were manually executed and error-prone, risking audit failures.

Scalability Issues:

On-premises storage couldn't scale for high transaction workloads.

The Zaptoz Solution

Zaptoz delivered a secure, automated AWS storage strategy focused on data protection, compliance, and cost optimization.

Key Solution Components

Amazon S3 for storing payment data with versioning, server-side encryption (KMS), and access logging.

Amazon S3 Glacier & Deep Archive for long-term data retention and cost optimization.

Amazon EBS (gp3 & io2) volumes for high-performance application and database workloads, fully encrypted.

AWS Backup automated daily, weekly, and monthly backups for S3, RDS, and EBS, including cross-region replication.

Amazon CloudWatch for real-time monitoring, anomaly detection, and usage insights.

AWS CloudTrail for full audit logging of all storage and backup API activities.

AWS IAM enforced least-privilege access for roles handling sensitive financial data.

Security, Compliance & Governance

Data Classification:

Amazon Macie automatically scanned all S3 buckets to detect and classify sensitive PII and financial data, triggering alerts for remediation.

Compliance Monitoring:

AWS Config tracked all resource configuration changes, ensuring adherence to RBI and PCI-DSS baselines.

Backup Verification:

AWS Backup Audit Manager generated verifiable compliance reports and validated backup integrity.

Threat Detection:

Amazon GuardDuty monitored for unusual access patterns and potential intrusions.
