All 177 designsReal-time Financial Transaction Microservice
Design a high-performance, low-latency microservice that processes real-time financial transactions, focusing on how the choice and optimization of a memory allocator like jemalloc would influence its resource footprint, throughput, and responsiveness.
SysDesAi
Real-time Session Expiration Notification
Design a secure, real-time web application where the backend proactively notifies the frontend about HTTP session expiration using WebSockets. Detail the server-side architecture for detecting session destruction and pushing notifications, and the client-side mechanism for handling these events gracefully to ensure a smooth user experience.
SysDesAiScalable Web Service Infrastructure
Design a highly available and scalable web service infrastructure that handles millions of concurrent users. Detail how you would implement load balancing, including the choice of algorithms (e.g., Least Connections, Weighted Round Robin), health check mechanisms, and strategies for zero-downtime deployments and session persistence.
