Doug Patti is a developer in Jane Street’s Client-Facing Tech
team, where he works on a system called Concord that undergirds
Jane Street’s client offerings. In this episode, Doug and Ron
discuss how Concord, which has state-machine replication as its
core abstraction, helps Jane Street achieve the reliability,
scalability, and speed that the client business demands. They’ll
also discuss Doug’s involvement in building a successor system
called Aria, which is designed to deliver those same benefits to
a much wider audience.
