Compliant, Secure, and Built for Transaction Scale

We build on AWS PCI-DSS certified services (ECS, RDS, KMS, CloudFront) and implement the full control framework around them. That includes network segmentation with dedicated VPCs for cardholder data, encryption at rest and in transit with customer-managed KMS keys, CloudTrail logging for every API call, and automated compliance checks via AWS Config and Security Hub. You get a compliance matrix mapped to every PCI-DSS requirement with evidence collection built in.

Infrastructure cost depends on transaction volume and compliance requirements. A startup processing under 100K transactions/month typically runs $3K-8K/month on AWS. Mid-scale operations (1M+ transactions) range $15K-40K/month. We architect for cost efficiency from day one with reserved capacity, Savings Plans, spot instances for non-critical workloads, and right-sizing. Most clients see 30-50% cost reduction after our optimization pass.

Yes. We run a phased migration that maintains zero downtime for transaction processing. First we set up the compliant landing zone with all security controls. Then we migrate workloads in priority order, starting with non-critical systems, validating each phase before moving the next. Payment processing migrates last with full rollback capability. Typical migrations complete in 8-16 weeks depending on complexity.

We use a combination of ElastiCache (Redis) for hot data, DynamoDB with DAX for single-digit millisecond reads, CloudFront edge locations for API acceleration, and purpose-built VPC networking with placement groups. Database queries are optimized with read replicas positioned in the same AZ as compute. We also implement connection pooling and keep-alive to eliminate cold start overhead.

Our architectures auto-scale horizontally at every layer. ECS/EKS services scale based on custom metrics (queue depth, transaction latency, CPU), not just generic thresholds. DynamoDB uses on-demand capacity. We pre-warm load balancers and CloudFront distributions before known events. SQS queues absorb burst traffic and prevent downstream overload. We also run load tests simulating 10x normal traffic before every major event.

Yes. We implement active-passive or active-active multi-region architectures depending on your RPO/RTO requirements. DynamoDB Global Tables provide sub-second replication. RDS uses cross-region read replicas with automated failover. Route 53 health checks trigger DNS failover in under 60 seconds. S3 Cross-Region Replication handles object storage. We test failover procedures quarterly and document every runbook.
