Hey All I've tried searching both Google and ET with little success. Here's what I'm hoping for... I would like to find some resources (books/papers etc..) that provide an outline/architecture of a high performance trading environment. For example, if I were a hedge fund, what type of hardware+software architecture would I have? ie. how many data feeds(main + failover), raid systems, backups, db's(Oracle/SQL/in memory). Would I use a message queues? How about clusters(metooxx)? I hope you get the idea. Would you really use TS and a T1 if you had 100mil fund? I wouldn't think so, so where would you start to design an "enterprise solution"? Are there off the self solutions? In my head I see this (I'm pulling the ranges out of thin air) ... Joe DayTrader -> HF w/ 10mill uses TS and a T1 with a Raid. HF w/ 10 mil+ -> HF w/200 mill uses ??????(fill in with resources here!) HF w/200+ builds their own. Any resources would be appreciated.
