About the Project

Antrein is a fault-tolerant virtual waiting-room platform designed to handle extreme traffic surges during high-demand events. It is built using Go-based microservices communicating via gRPC and Server-Sent Events (SSE), deployed on Kubernetes with a custom Go reverse proxy. The system supports dynamic, event-based infrastructure provisioning, automatically scaling compute resources up and down based on event start and end times to ensure both performance and cost efficiency.
