Illustrative exampleScaling a FinTech payment platform
A fast-growing FinTech payments provider
Handling rapid growth without slowing down
- Industry
- FinTech / payments
- Scale
- 50,000+ transactions per second
- Compliance
- PCI-DSS Level 1
- Platform
- Google Cloud
The challenge
- Transaction volume grew 10x
- During peak hours, processing delays hit more than 10 seconds
- Failed transactions and customer complaints
- Upcoming PCI-DSS audits flagged security risks
What it had to do
- Process tens of thousands of transactions per second
- Maintain sub-second latency
- Scale globally
- Meet financial compliance standards
What we built
CloudMagic rebuilt the system as a cloud-native microservices architecture on Google Cloud. Each service scales on its own, traffic is balanced across regions, and the old central database gave way to a globally consistent one built for financial workloads.
