About the Project
The client needed a secure and automated system to ingest, validate, transform, and store large volumes of files received from multiple internal and external sources. Manual file transfers were creating delays, errors, compliance risks, and inconsistent reporting.
Inexture built a fully automated ETL + file transfer ecosystem with enterprise-grade security, real-time notifications, and scalable cloud infrastructure.
Client Requirements
- Secure file upload, download & retention
- Encryption for data in transit & at rest
- Automatic mapping & transformation of raw file formats
- Schedule-based and real-time ETL execution
- Retry & error-handling pipelines
- High availability for ingestion
- Data validation & cleansing rules
- Logging, auditing & compliance support
Challenges We Solved
- Highly inconsistent file formats across sources
- Large daily file volume causing processing delays
- No existing infrastructure for tracking errors or retries
- Required secure transfer for confidential financial datasets
- Needed auto-scaling solution without increasing costs
- Required flexibility for future ETL workflows
Our Solution & Architecture
Inexture architected a secure, cloud-native ETL system using automated schedulers, containerized processors, and real-time notifications.
Automated ETL Pipeline
- Auto ingestion from secure endpoints
- Schema validation & cleansing
- Transformation & mapping logic
- Processed output delivered to destination systems
Secure File Transfer Module
- SFTP & HTTPS digital transfer channels
- AES-256 at-rest encryption
- TLS 1.2/1.3 during transit
Scalable Cloud Infrastructure
- AWS S3 for storage
- AWS Lambda for serverless processing
- AWS RDS for structured datasets
- CloudWatch for logs & monitoring
Advanced Workflow Automation
- Scheduled CRON triggers
- Event-driven ETL executions
- Multi-stage process orchestration
