Secure, event-driven AWS data pipeline (S3 + Lambda) demonstrating scalable ingestion and processing aligned to Well-Architected principles
AWS Data Pipeline Architecture
Diagram illustrates event-driven ingestion and processing workflow using S3 and Lambda.
Event-driven serverless architecture designed for scalable, secure ingestion and processing of mission data.
- Amazon S3 (data ingestion and storage)
- AWS Lambda (serverless processing)
- AWS IAM (access control)
- Amazon CloudWatch (logging and monitoring)
- AWS CLI (command-line interaction and validation)
- User uploads JSON data to S3 Raw Bucket
- S3 triggers AWS Lambda via event notification (ObjectCreated)
- Lambda processes and transforms the data
- Output is written to S3 Processed Bucket
- Execution logs are captured in CloudWatch

}This solution is designed using an event-driven serverless architecture aligned to AWS best practices.
- Scalability: Amazon S3 and AWS Lambda enable automatic scaling based on incoming data volume
- Decoupling: S3 event notifications allow loosely coupled ingestion and processing layers
- Separation of concerns: Raw and processed data are stored in separate buckets to maintain data integrity and traceability
- Extensibility: Additional processing steps (e.g., enrichment, analytics) can be added without modifying ingestion logic
- IAM roles enforce least-privilege access between S3 and Lambda
- Data stored in S3 can be encrypted at rest using AWS-managed encryption capabilities
- Access to buckets can be restricted via bucket policies
- Logging via CloudWatch enables auditability and monitoring

Lambda vs EC2:
Lambda provides scalability and low operational overhead, but introduces execution limits and less control over runtime -
Event-driven vs batch processing:
Event-driven enables real-time processing but adds architectural complexity -
S3 storage tiers:
Standard storage is used for simplicity, with tradeoffs in cost compared to archival tiers
This architecture aligns with AWS Well-Architected Framework principles:
- Security: IAM roles, encryption, controlled access
- Reliability: S3 durability and event-driven processing
- Performance Efficiency: Serverless scaling with Lambda
- Cost Optimization: Pay-per-use model
- Operational Excellence: Logging and monitoring via CloudWatch
This architecture reflects common Intelligence Community data ingestion patterns, where event-driven processing enables scalable, auditable, and secure transformation of mission data across distributed systems.
