VirtuArch Solutions demonstrates a production-grade AWS security architecture spanning identity, network, application, and data tiers across two availability zones in eu-west-1. Microsoft Entra ID integrates via SCIM sync to IAM Identity Center, enforcing SSO and RBAC across EC2, Fargate, Lambda, and ECS workloads protected by security groups and NACLs. KMS, Secrets Manager, and Certificate Manager encrypt data at rest and in transit, while VPC endpoints for S3, KMS, SSM, CloudWatch Logs, SQS, and ECR eliminate internet exposure for sensitive operations. CloudFront, ALB, API Gateway, and Route 53 front the application tier; RDS Aurora (primary/standby), ElastiCache, DynamoDB, and Redshift power the data layer with multi-AZ resilience and encryption. CloudTrail, GuardDuty, Security Hub, Config, Inspector, and Macie provide continuous compliance monitoring and threat detection across all layers. Fork this diagram on Diagrams.so to customize subnets, security groups, or add additional AWS services like WAF rules, VPN endpoints, or cross-region replication. This architecture exemplifies zero-trust principles, least-privilege access, and defense-in-depth controls essential for regulated workloads.
