End-to-End Scenarios
Simfra's service implementations were developed and tested through realistic application deployments. Each scenario below represents a complete system - provisioned with Terraform, deployed through CI/CD pipelines, and validated with automated test suites. When a scenario required a cross-service integration (DynamoDB Streams triggering Lambda, EventBridge routing to Step Functions, EKS pods assuming IAM roles), that integration was built and debugged until the full application worked end to end. The result is a set of 19 validated deployments that prove Simfra works as a complete AWS environment, not a collection of isolated API stubs.
Every scenario includes Terraform infrastructure, application code deployed through CI/CD (CodeCommit, CodeBuild, CodeDeploy, CodePipeline), and automated tests covering smoke checks, integration workflows, security validation, and performance under concurrency.

Traditional and Serverless
- 3-Tier Application - EC2 instances behind public and internal load balancers, backed by RDS PostgreSQL. Full CI/CD with CodeCommit, CodeBuild, CodeDeploy, and CodePipeline.
- Serverless Trading API - API Gateway V2 with Cognito JWT authorization, Lambda functions in Go, and DynamoDB with KMS encryption. CI/CD deploys Lambda via CodeDeploy AllAtOnce traffic shifting.
- Event-Driven Order Processing - DynamoDB Streams trigger Lambda, which emits EventBridge events that start Step Functions workflows. Includes inventory reservation, payment processing, and SNS/SQS notifications.
- Static Web Hosting - S3 static website with CloudFront CDN and Route53 DNS. Validates content delivery, caching, and origin access control.
Analytics and Batch Processing
- Data Lake Analytics - Kinesis ingestion with dual consumers (Firehose to S3 and Lambda enrichment), Glue crawlers for schema inference, and Athena SQL queries against the cataloged data.
- Batch Rendering Farm - Step Functions orchestrate Lambda validation, Batch array jobs with EFS shared storage, and SNS/SQS completion notifications.
- Trade Surveillance Lakehouse - Kinesis streaming with triple consumers (Firehose, Lambda enrichment, KAV2 pattern detection), Glue crawlers, and Athena compliance queries for wash trade and spoofing detection.
Container Platforms
- ECS Microservices Platform - Three ECS Fargate services with Cloud Map DNS discovery, RDS PostgreSQL, ElastiCache Redis, and ALB with ACM TLS.
- WordPress on ECS - WordPress on ECS Fargate with real NFS-backed EFS for shared wp-content, RDS MySQL, and CloudFront CDN.
- Flagship Retail Community Hub - Hybrid architecture with Lambda API, ECS background worker, five DynamoDB tables, EventBridge event fan-out, and AppConfig for live configuration.
Kubernetes and EKS
- EKS Fraud Detection - Streaming fraud detection on EKS with IRSA pod identities, Kinesis consumption, DynamoDB feature storage, and EventBridge/SNS/SQS alerting.
- Mattermost on EKS - Upstream Mattermost deployed on Kind-backed EKS with RDS, ElastiCache, S3, and SES email delivery.
- GitLab on EKS - Self-managed GitLab via Helm chart on EKS with external PostgreSQL, Redis, five S3 buckets, and SES email.
- Airbyte on EKS - Airbyte data integration platform on EKS with External Secrets Operator, IRSA-based controllers, and custom image builds via CI/CD.
Specialized Workloads
- Multi-Account Security Operations - Organizations with delegated GuardDuty, Security Hub, Config, and Access Analyzer across multiple accounts. EventBridge finding enrichment with Lambda.
- Asset Servicing Operations - Financial platform with CQRS (RDS writes, DynamoDB reads), Kinesis stream processing, ECS polling workers, and DynamoDB Streams reconciliation.
- Multi-Region ARC Failover - Payment gateway across two regions with ARC Zonal Shift for AZ-level impairments and ARC Region Switch plans for full regional failover via Route 53 weighted routing.
- SageMaker ML Pipeline - Full ML lifecycle with CI/CD-built container images: CodeCommit source, CodeBuild Docker builds, ECR storage, SageMaker model training, endpoint deployment, real-time inference, and batch transform.
- Masters of Simfra - Persistent browser MMO 4X strategy game with timestamp-driven resource accumulation, build/research queues, fleet dispatch, asynchronous combat resolution via ECS workers, and live-ops balance tuning via AppConfig.
