High Performance Political Revolutions

on YouTube ↗37m

" summary

A Rails fundraising platform that handles spikes of 300,000 requests/min and 42 credit-card transactions/sec and still never drops contributions; it runs a 12-year Rails app for 16,600 organizations and uses ActBlue Express tokenization with a dedicated vault, batches settlements to reduce bank posts, and keeps a 97% hit rate via Fastly CDN. Operational tools include NGINX load balancing, Postgres replicas, Redis, statsd-ruby + Graphite for metrics, and Sidekiq queues plus Papertrail logs; the system accepts donations continuously and succeeds in practice.
