All software is developed in the U.K. in Java, which Moss said was more mature than .Net when it moved from ASP over three years ago.

For storage, Betfair's tier-1 system is supplied by Hitachi Data Systems (HDS) which houses the transaction database, and for tier-2 storage like logs, and the data warehouse, NetApp is the preferred vendor.

There is about 22TB of both HDS and NetApp storage capacity, he said.

Moss said he has been lucky that there are some highly-skilled IT people in Tasmania because there aren't many specialist IT companies.
