Architect a multi-region Active-Active credit card issuer system by adopting a microservices-based design on AWS. This approach uses strategic AWS service selection to achieve 99.99% availability and high-TPS authorization workflows while maintaining on-premises settlement.

Mitigate DynamoDB tail latency in credit card authorization workflows by applying request hedging patterns. This performance optimization technique ensures high throughput and consistent response times required for mission-critical payment processing.

Yes, you can maintain on-premises settlement during credit card authorization migration. The reference architecture supports a hybrid model, allowing resilient AWS microservices to handle authorization while integrating with existing on-premises settlement systems.

Yes, the architecture satisfies strict PCI DSS compliance requirements for credit card processing workloads. It achieves this through strategic AWS service selection and specific architectural patterns designed for highly regulated financial environments.

Design a credit card reconciliation system for 5,000 TPS by selecting appropriate databases for specific transaction needs and utilizing a microservices architecture. This ensures the required high throughput and 99.99% availability.

You need request hedging for payment microservices on AWS when high-TPS authorization workflows demand strict performance guarantees. It specifically mitigates DynamoDB tail latency, ensuring the system maintains its required throughput and availability.
