Building a Multi-Tenant Image Service Platform
34 min read • Published onThis document presents the architectural design for a cloud-agnostic, multi-tenant image processing platform that provides on-the-fly transformations with enterprise-grade security, performance, and cost optimization. The platform supports hierarchical multi-tenancy (Organization → Tenant → Space), public and private image delivery, and deployment across AWS, GCP, Azure, or on-premise infrastructure. Key capabilities include deterministic transformation caching to ensure sub-second delivery, signed URL generation for secure private access, CDN integration for global edge caching, and a “transform-once-serve-forever” approach that minimizes processing costs while guaranteeing HTTP 200 responses even for first-time transformation requests.
