Building a Multi-Tenant Image Service Platform
This 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.System OverviewComponent NamingArchitecture PrinciplesTechnology StackHigh-Level ArchitectureData ModelsURL DesignCore Request FlowsImage Processing PipelineSecurity & Access ControlDeployment ArchitectureCost OptimizationMonitoring & Operations

CSP-Sentinel Technical Design Document
CSP-Sentinel is a centralized, high-throughput system designed to collect, process, and analyze Content Security Policy (CSP) violation reports from web browsers. As our web properties serve tens of thousands of requests per second, the system must handle significant burst traffic (baseline 50k RPS, scaling to 100k+ RPS) while maintaining near-zero impact on client browsers.The system will leverage a modern, forward-looking stack (Java 25, Spring Boot 4, Kafka, Snowflake) to ensure long-term support and performance optimization. It features an asynchronous, decoupled architecture to guarantee reliability and scalability.

Migrating E-commerce Platforms from SSG to SSR: A Strategic Architecture Transformation
This comprehensive guide outlines the strategic migration from Static Site Generation (SSG) to Server-Side Rendering (SSR) for enterprise e-commerce platforms. Drawing from real-world implementation experience where SSG limitations caused significant business impact including product rollout disruptions, ad rejections, and marketing campaign inefficiencies, this playbook addresses the critical business drivers, technical challenges, and operational considerations that make this architectural transformation essential for modern digital commerce.
