When an AI data centre starts a training run, the grid feels it. Oracle's infrastructure chief explained what the company does about that, and more.

I was at Oracle AI World last week. Here's what I heard from its leadership.

### Designing AI data centres

According to Mahesh Thiagarajan, president of Oracle Cloud Infrastructure (OCI), an AI data centre draws so much power that it can affect the power grid itself.

This might arrive as a large step change as swathes of GPUs fire up or shut down, or as the synchronous power draw of massive GPU clusters during AI training.

As a result, a large AI data centre must be designed with UPS batteries to absorb the load swings and software to damp harmonic oscillation. Both are deployed as standard across OCI.

In addition, Oracle has "completely changed" its data centre power strategy in the wake of community concerns, Mahesh says. He pointed to a non-combustion, fuel-cell solution that the company hopes to deploy soon.

### Fusion Claw: when 100 agents weren't enough

Power isn't the only area where Oracle has rethought its approach. Unveiled in September, Oracle's Fusion Claw blends frontier AI for planning and reasoning with deterministic software to handle repetitive, high-volume transactions.

For those still sceptical of it, Chris Leone explained that Fusion Claw came about because agentic applications had hit a ceiling on hard, high-volume problems.

One example Leone gave was a holiday-rental customer pulling a billion records a month into the general ledger, complete with subledger detail to recognise revenue.

The solution started as a "Codex in a container" that sat next to the data. This evolved into Fusion Claw, which comes with a data set and a set of actions and skills, and effectively replaces 50 to 100 specialised agents.

### The three-year roadmap is dead

I also had the chance to speak with Christopher G. Chelliah, an Oracle senior vice president for Japan and APAC. In our conversation, he offered some startling insights. The three-to-five-year IT horizon is no more, traditional sales cycles have collapsed, and platform and language choices no longer matter.

I agree with him, what with users already using AI to reverse engineer the firmware of TVs or port games from legacy platforms. His anecdotes were an eye-opener, though.

Chelliah spoke of a port authority CIO who reached out after seeing a post on optimising port operations on, of all places, LinkedIn. A working prototype, populated with the customer's data, was put together in two weeks.

How's that for a collapsed sales cycle?

So how can APAC organisations get ahead, I asked. His response was threefold: put away the old mindsets and methods, get your feet wet privately, and embrace AI at the organisational level.

The question, then, is no longer whether your organisation is ready for AI. It's what, exactly, is stopping you.
