Performance and Scaling for Special Events at eTF1
summary
MyTF1 validated platform replication and full-scale load tests to handle World Cup live traffic, simulating 1.5M logins, 10k connections/sec, ad bursts up to 75k req/sec and production peaks of 2.4M concurrent users (~576k req/sec at CDN edge). Tests used a GCP Cassis stress cluster and AWS EKS with tuned HPA, pre-warmed node groups and ALB adjustments; observability with Datadog and Prometheus/Grafana was used for profiling, and plans include adopting KEDA and Carpenter to address remaining infra and monitoring gaps while keeping authentication live.
