To prevent disruptions and scale up its service while keeping costs down, Twitter has had to drastically change its core infrastructure, taking up open source tools while doing so.
Twitter processes about 6,000 messages a second, adding up to more than 500 million messages per day or about 3.5 billion a week. And at one peak time, Twitter handled a record 143,000 messages in one second during the airing of the movie “Castle in the Sky” in Japan earlier this year, said Chris Aniszczyk, head of open source computing at Twitter during LinuxCon Europe in Edinburgh on Monday.
