Being Uber with Node
summary
Moves a live service from a LAMP prototype to a Node-based dispatch, claiming zero lost requests during rolling deploys and live migration. Implements request manager to drain and restart processes, a slave master election and state serialization for failover, a MongoDB wrapper with journaling, and connection-node tiers fronting phones. Runs on about ten servers across dispatch, connection, and API tiers, powers expansion to new cities, and ships a realtime map called godview that actually works in production.
