Code Architecture Planner

Act as a senior software architect with 15+ years of experience designing scalable, maintainable systems. Design a comprehensive software architecture for [PROJECT DESCRIPTION] with an expected scale of [EXPECTED USERS/LOAD]. Provide a detailed architectural plan covering: **1) High-Level System Architecture** - Overall system architecture diagram description - Core components and their responsibilities - Service boundaries and communication patterns - Data flow between components - Integration points and external dependencies **2) Technology Stack Recommendations** - Frontend framework and justification - Backend language/framework selection - Database choices (relational, NoSQL, caching) - Message queues and event streaming - Deployment and containerization strategy - Monitoring and logging solutions **3) Database Design & Schema** - Database architecture (single/multiple databases) - Core entity relationships and schema design - Data partitioning and sharding strategy - Backup and disaster recovery approach - Performance optimization techniques **4) API Design & Communication** - API architecture (REST, GraphQL, gRPC) - Endpoint design and versioning strategy - Authentication and authorization approach - Rate limiting and security considerations - Inter-service communication patterns **5) Security Architecture** - Authentication and authorization framework - Data encryption (at rest and in transit) - Security best practices implementation - Vulnerability mitigation strategies - Compliance considerations (GDPR, SOX, etc.) **6) Scalability & Performance Strategy** - Horizontal and vertical scaling approaches - Load balancing and traffic distribution - Caching strategies (Redis, CDN, application-level) - Database optimization and query performance - Monitoring and alerting setup **7) Deployment & Infrastructure** - Cloud provider recommendations and services - CI/CD pipeline architecture - Container orchestration (Kubernetes, Docker) - Infrastructure as Code (Terraform, CloudFormation) - Development, staging, and production environments **8) Development & Maintenance Strategy** - Code organization and project structure - Testing strategy (unit, integration, end-to-end) - Documentation and knowledge management - Team collaboration and development workflow - Technical debt management approach **9) Risk Assessment & Mitigation** - Single points of failure identification - Disaster recovery and business continuity - Performance bottlenecks and mitigation - Security risks and countermeasures - Scalability limitations and solutions **10) Implementation Timeline & Phases** - Development phases and milestones - MVP feature set and core functionality - Progressive enhancement strategy - Resource requirements and team structure - Go-to-market technical considerations Format as a comprehensive architectural document with clear sections, technical diagrams descriptions, and specific technology recommendations with rationale. **Input Variables to Replace:** - PROJECT DESCRIPTION: [Detailed description of your software project] - EXPECTED USERS/LOAD: [Expected number of users, requests per second, data volume]
