Multi-AZ AWS architecture implementing ASPICE 3.1 process controls across presentation, application, data, and toolchain layers for automotive and safety-critical software development. Traffic flows from End Users through Route 53 and CloudFront to dual availability zones, each with public subnets hosting ALBs, private app subnets running EC2 and ECS Fargate microservices, private data subnets with RDS MySQL, DynamoDB, and ElastiCache, and isolated ASPICE toolchain subnets managing requirements, design, testing, and configuration. AWS WAF, Shield, IAM, CloudWatch, and CloudTrail provide security, compliance monitoring, and audit trails required for functional safety standards. This architecture demonstrates how to embed ASPICE process governance (SWE, SUP, MAN processes) into cloud infrastructure while maintaining high availability and regulatory traceability.
