These issues were evident at Tech Week Singapore from Sept. 29 to 30, where equipment suppliers drew crowds at exhibitions such as Data Center World Asia and Cloud and AI Infrastructure.

As AI systems become more complex, operators face mounting pressure to deliver greater computing capacity while curbing electricity and water consumption by the vast, stand-alone facilities being erected across the globe today.

"Data centers evolved from computer rooms used by governments, banks and large institutions during the 1950s and 1960s," said Srini Rao, head of ecosystems at Novagate Cloud.

Indonesia has 468 MW of operational capacity and nearly 2,000 MW in development.

Meanwhile, Malaysia leads the three markets with 1,318 MW operational capacity and 5,438 MW in its development pipeline.
