Trends Shaping Indonesia’s Data Center Landscape

Indonesia’s data center market is growing rapidly:

• The nation hosts 100+ operational facilities and dozens more under development.
• Jakarta remains the dominant data center market, accounting for a significant portion of national capacity.
• Secondary hubs like Batam are emerging as strategic locations due to geography and connectivity.
• Major operators are integrating renewable energy and advanced cooling techniques to build AI-ready, sustainable infrastructure capable of supporting high-density computing.

Indonesia’s data center ecosystem is transitioning from a concentrated set of enterprise and colocation facilities to a mature, diversified infrastructure landscape anchored by hyperscale and renewable-ready campuses. Facilities like BDx’s Jatiluhur CGK4 and DCI Indonesia’s H1 Campus (JK6) exemplify the country’s capacity ambitions, while multi-tenant and global operator facilities ensure connectivity and service diversity. As demand for cloud, AI, and edge computing continues growing, Indonesia’s largest data centers will play an increasingly central role in enabling digital transformation across ASEAN and beyond.
