How to win $1,000,000,000 - The Technology of Lotteries
summary
Allwin Lottery Solutions runs systems that handle spikes from ~6,000 to 10,000 logins per minute, sells ~1.35M tickets on an average Saturday, and deals with odds like 1-in-139M for EuroMillions and ~1-in-300M for Powerball with jackpots up to $2B. Engineering stories include a scanner bug that showed winners as non-winning (scanner disabled for four months, regulator fine near €500,000), an OnDemand Resources workaround for Apple, and the tradeoffs of Cassandra vs relational designs across monolith and microservice eras.
