Challenge

A major payment processing company in Latin America operated critical transaction systems from aging on-premise infrastructure. With transaction volumes growing 40% year-over-year and regulatory pressure for improved disaster recovery, they faced mounting technical debt and availability concerns. Their legacy deployment process required planned maintenance windows, resulting in lost revenue during peak hours.

Key Challenges:

  • Aging on-premise infrastructure with 15+ year-old systems
  • Planned downtime required for every deployment (avg. 4 hours/month)
  • No disaster recovery site - single point of failure
  • Manual deployment process taking 3-5 days per release
  • PCI-DSS compliance gaps requiring immediate attention
  • Infrastructure costs growing 25% annually with no scalability

Solution

We designed and executed a phased migration strategy using the AWS Migration Acceleration Program methodology. The approach prioritized critical payment rails while building modern CI/CD capabilities in parallel. We implemented a multi-AZ architecture with automated failover and established GitOps practices for infrastructure management.

What We Implemented:

  • Multi-AZ architecture across 3 availability zones with automated failover
  • Blue-green deployment pipeline enabling zero-downtime releases
  • Infrastructure as Code with Terraform for reproducible environments
  • Containerized workloads on EKS with auto-scaling policies
  • Centralized logging and monitoring with CloudWatch and Datadog
  • Secrets management with AWS Secrets Manager and HashiCorp Vault

Solution Architecture

Component 1
VPC with public/private subnets across 3 AZs
Component 2
Amazon EKS for container orchestration (production workloads)
Component 3
Amazon RDS PostgreSQL Multi-AZ for transactional databases
Component 4
Amazon ElastiCache Redis for session management and caching
Component 5
Amazon MSK (Kafka) for event streaming between services
Component 6
AWS WAF + Shield Advanced for DDoS protection
Component 7
AWS Transit Gateway for hybrid connectivity
Component 8
Amazon CloudFront for API acceleration
