This deliverable is a fully functional, production-ready web application built for high availability and performance. The architecture utilizes modern Client-Side Rendering (SPA) and a Serverless/Microservices backend, integrated and deployed entirely within the designated cloud environment via an automated CI/CD pipeline for zero-downtime releases. 2. Key Technology & Architecture Component Architecture & Technologies Deployment & Scaling Front-End (SPA) Built using a leading framework (e.g., React/Angular) with Tailwind CSS. Fully responsive and adheres to WCAG 2.1 AA accessibility standards. Static assets served via Global CDN for low latency. Back-End (API/Data) RESTful APIs secured with JWT. Core logic leverages a Serverless approach for efficiency and auto-scaling. Hosted on PaaS (e.g., Cloud Run/Functions) for elastic auto-scaling based on real-time load. Data Persistence Scalable NoSQL (e.g., Firestore) or managed Relational Database service. Includes automated daily backups and point-in-time recovery. 3. Quality & Assurance Requirements Requirement Area Deliverable Assurance Security HTTPS encryption (TLS 1.2+). OWASP Top 10 protection. Role-Based Access Control (RBAC) enforced. Performance Page Load Time (LCP) under 2.5s. API latency under 200ms. Optimized for Core Web Vitals. Operations Integrated Logging, Monitoring (APM), and Alerting. CI/CD for automated testing and Blue/Green/Canary deployments. 4. Final Deliverables Production Deployment: Functional application accessible at the agreed-upon public URL. Source Code: Complete, version-controlled repository (Front-end and Back-end). Documentation: Architecture diagrams, API specs, and operational guides. Access: Credentials for monitoring dashboards and CI/CD pipeline management.
