But with virtualisation, server provisioning is now a breeze, according to Yap. "Instead of weeks or even months, you now cut down to minutes where I can execute server provisioning. Within a day we should be able to provision it and then go in the application to run the tests."
Virtualisation also makes disaster recovery a much easier affair, says Yap. At the same time it also helps to increase uptime. "In the past in disaster recovery I need to have the same full set of similar machines, components and cards, if not, it will not work," says Yap.
"Now you don't need to because it is software controlled rather than hardware controlled. Therefore it does really help to improve the way disaster recover can be done," says Yap.
Looking back at his virtualisation journey, Yap says one key benefit has been physical space optimisation. "You do not need to find a bigger space because there is good optimisation in the floor area," he says.
So what is next for Yap in his virtualisation strategy? The next phase for him is in the area of desktop virtualisation. He believes there are members of the Resorts World Sentosa workforce that do not require dedicated desktops. "I think that's where we can have more simplicity in client devices. All this simplicity means lower costs, better efficiency and productivity," he says.
