A cost-efficient storage migration project from AWS S3 to MinIO, leveraging FastAPI for backend integration. The solution ensures S3-compatibility, improved flexibility, stable performance, and significant cost savings with open-source object storage.
Project: Cloud Infrastructure Optimization & Cost Reduction
The Challenge:
Rising AWS S3 storage costs were impacting financial sustainability, coupled with a need for greater deployment flexibility and control over our storage infrastructure.
The Solution:
Led the migration from AWS S3 to a self-hosted MinIO object storage solution. The key was ensuring full S3-compatibility while refactoring the backend for maintainability.
- Engineered a centralized service layer to consolidate storage logic from 40+ duplicated API endpoints.
- Ensured seamless integration with existing systems using MinIO's S3-compatible API.
- Implemented a new monitoring stack for on-premise object storage performance.
Technical Highlights:
- Backend: FastAPI, Python
- Storage: AWS S3, MinIO
- Architecture: API consolidation, S3-Compatible Integration, On-Premise Deployment
The Outcome:
- Significant reduction in cloud storage costs,
- Achieved greater infrastructure flexibility and control,
- Established a more maintainable and scalable codebase,
- Stable performance under high-load conditions.
