myGLOBAL PEET is a comprehensive AWS-native SaaS platform integrating core data services, event-driven workflows, domain-specific modules, and AI inference across six subnets within a VPC. Data flows from Platform Entry through CloudFront, WAF, and ALB into the Core Data layer (Aurora, RDS, DynamoDB, S3), then through EventBridge, Kinesis, and MSK Kafka to domain modules (myWORKS, mySUPPORT, mySITE, myBOT, myATHENA) and AI services (Bedrock, SageMaker, Comprehend). This architecture demonstrates enterprise-grade patterns for multi-tenant SaaS: centralized authentication via Cognito, event-driven orchestration with Step Functions, AI inference via Bedrock and EKS, and actionable output delivery through SNS and SES. Solutions architects can fork this diagram to customize domain modules, adjust subnet sizing, or integrate additional AWS services like AppConfig or Systems Manager. The design balances security (KMS encryption, Lake Formation governance), scalability (ECS, EKS, Lambda), and observability (CloudWatch, X-Ray) for mission-critical field service platforms.
