Work Breakdown Structure and deployment architecture for a comprehensive Online Class Management System spanning requirements, design, user management, course delivery, assessment, and reporting. The WBS decomposes the project into nine major phases from requirements gathering through deployment, while the deployment architecture illustrates a multi-tier cloud infrastructure with external zones, DMZ, application servers, databases, and monitoring. This structure demonstrates enterprise-grade system design principles including load balancing, database replication, caching, message queuing, and security controls essential for scalable educational platforms.
