DC site selection matrix for Southeast Asia:
Latency-sensitive front-end: Singapore (5/5)
AI training / batch: Batam (5/5)
Enterprise compliance: Singapore (5/5)
Cost-sensitive compute: Batam (5/5)
Multi-site resilience: Both
26+ submarine cables vs 60% cheaper electricity. The right answer depends on the workload.
The Singapore-Batam Digital Corridor is already being built.
Front-end in Singapore (peering, low-latency apps). Back-end in Batam (AI training, storage, DR). A dedicated 24-fiber-pair submarine cable connects them at under 2ms latency.
This is what happens when one location runs out of space and the other has cost advantages too large to ignore.
