Australia and New Zealand (ANZ) ranks fourth in worldwide adoption of grid computing.
According to the fourth Oracle Grid Index Report, ANZ ranked fourth behind the US, Germany and Nordic region.
The report found ANZ's adoption progressed by more than one index point, the sharpest rise in adoption worldwide in a six-month period.
The Asia Pacific & Japan (APAC) region progressed faster than the US and Europe -- recording 83 per cent growth in either planned or actual deployment.
ANZ has consistently kept pace with or led the APAC region since the Grid Index began in April 2005.
Companies that deploy a grid computing solution, utilising low cost commodity hardware, create a consolidated computing infrastructure that virtualises and provisions computing resources dynamically. This leads to a higher quality of service, improved performance and better reliability.
One local organisation that has implemented grid computing is the West Australian Department of Education.
The department has deployed Oracle Real Application Clusters 10g to link 19 Intel-based servers into a computing grid that will support 335,000 teachers and students across 800 state schools and training institutes.
The department's program manager Murray Neville said the solution is handling more than 30 per cent of its user base without performance bottlenecks.
"We use the grid to remove single points of failure in our infrastructure to create a highly available architecture; the grid allows us to scale out as our needs grow by simply adding new nodes over time," he said.
Oracle Australia's sales vice president Robert Gosling believes grid computing has reached a 'tipping point' where adoption rates are fast approaching mainstream.
"One thing is for sure, ANZ is leading the world in its pace of adoption and that's very exciting," he said.
NRMA has implemented grid computing for its call centre application and membership database.
Each cluster is comprised of three Dell 2850 servers running Linux accessing a single Oracle database hosted on EMC SAN storage.
The call centre application runs on Oracle Database9i while the membership database runs on Oracle Database 10g.
NRMA CIO Craig Gibbons said customers depend on 24 hour service, 365 days a year so an outage is unnaceptable.
Gibbons said internal policy at NRMA states that only two minutes of data loss is permissible for the Road Service application.
"Furthermore, all operations must be up and running within one hour, even if physical disaster strikes our operations. Grid computing delivers high availability."
Other organizations that have embraced grid computing includes the Commonwealth Bank of Australia, National Australia Bank and Clough Engineering.
