5 Data Centers Putting Johor on the Global Map
Malaysia has quietly become one of the most important data center markets in the world. Hyperscale campuses, gigawatt-scale builds, AI supercomputing, and renewable-powered facilities are all converging on a single corridor — and Johor is the epicenter. Here’s a closer look at five of the major data centers driving that shift. A few years ago, if you asked anyone in the industry where Southeast Asia’s data center action was, the answer was simple: Singapore. Today, that answer has changed. Singapore is still the strategic hub it always was, but capacity constraints, sustainability moratoriums, and skyrocketing demand have pushed hyperscalers, cloud providers, and enterprise operators to look just across the Causeway. The result? Johor is now one of the fastest-growing data center markets on the planet and Malaysia, more broadly, is building infrastructure at a scale that’s reshaping how the region handles AI workloads, cloud traffic, and cross-border data flows. Here’s a look at five major data centers in Malaysia that anyone tracking the region’s digital infrastructure should know. 1. Sedenak Tech Park (STeP) — Kulai, Johor Sedenak Tech Park is shaping up to be one of the most significant infrastructure projects in Southeast Asia’s recent history. Once fully operational, STeP is set to become the largest hyperscale data center campus in the region. The scale alone is hard to wrap your head around: 745 acres of dedicated tech park, designed from the ground up for hyperscale tenants, with up to 300 MW of critical IT load. That’s not just an expansion — that’s a regional anchor. STeP is the kind of facility that pulls hyperscalers, AI workloads, and cloud availability zones into Johor at a structural level, not just an opportunistic one. 2. YTL Green Data Center Park — Kulai, Johor YTL Green Data Center Park represents its AI ambition. This is the facility hosting NVIDIA’s AI supercomputing operations in Malaysia — a clear signal that the country isn’t just building generic compute capacity but is positioning itself as a serious AI infrastructure hub. The 500 MW capacity is paired with a 500 MW on-site solar farm, making sustainability a structural part of the build rather than a marketing afterthought. For anyone tracking where AI training and inference workloads are physically being deployed in Southeast Asia, YTL’s Kulai campus is one of the most important sites on the map. 3. AirTrunk Johor Bahru (JHB1) — Johor Bahru AirTrunk’s JHB1 is one of the cleanest examples of why Johor and Johor Bahru specifically — has become so attractive to hyperscalers. At 150 MW, JHB1 is purpose-built for major cloud availability zones, with direct, low-latency connectivity to Singapore that lets operators tap Johor’s land and power advantages without losing the network proximity that makes Singapore so valuable in the first place. This is the model a lot of new builds in the region are following: deploy capacity in Johor, anchor it to Singapore through high-quality fiber. JHB1 was an early proof point that the model works. 4. Cyberjaya I — Cyberjaya, Selangor Not all of Malaysia’s data center story is in Johor. Cyberjaya the country’s original tech corridor near Kuala Lumpur continues to play an important role, particularly for enterprise and regional cloud workloads. Cyberjaya I stands out for its near-zero Water Usage Effectiveness (WUE), a metric that’s quietly become one of the most important measures of sustainable data center operations. As global scrutiny on water consumption in data centers intensifies — particularly for AI workloads, which can be water-intensive — facilities like Cyberjaya I are setting an operational standard the rest of the industry will eventually have to meet. 5. Open DC PE2 — Bayan Lepas, Penang The fifth facility on the list points to something just as important as Johor’s hyperscale story: Malaysia’s data center growth is geographically diversifying. Open DC’s PE2 in Bayan Lepas, Penang, is currently the largest data center on the island and represents the broader push to extend digital infrastructure beyond the Kuala Lumpur–Cyberjaya and Johor corridors. Penang has long been a manufacturing and semiconductor hub; building serious data center capacity there extends the country’s digital footprint into a region with strong industrial demand and its own unique connectivity profile. For enterprises in northern Malaysia and for anyone needing redundant capacity outside the southern corridor PE2’s expansion matters. Why Malaysia, Why Now? Step back from the individual facilities and the bigger picture comes into focus. A few forces are converging at the same time: The result is a market that’s gone from regional player to one of the most important data center geographies in the world — fast. The Connectivity Layer Is Where It All Comes Together Here’s the part that often gets missed in conversations about Malaysia’s data center boom: a data center is only as strategically useful as the network connecting it. A 300 MW hyperscale campus in Kulai is impressive. But what makes it valuable to global operators is the fiber linking it to Singapore, to other Johor campuses, to the rest of Malaysia, and ultimately to the broader Asia-Pacific footprint. AI workloads, cloud availability zones, real-time applications, and cross-border data flows all live or die on that connectivity layer. As Malaysia’s data center market continues its explosive growth — capacity in Malaysia jumped from 120 MW to 690 MW in just the first half of 2025 alone — the demand for diverse, low-latency, resilient fiber routes between these facilities is accelerating with it. Building the Connectivity Layer for Malaysia’s Data Center Era At DCConnect, this is exactly the layer we’re built for — and Johor is where we’ve planted some of our deepest roots. We have a strong, established presence across Johor, with diverse fiber routes interconnecting the major hyperscale campuses, colocation facilities, and cross-border links that define the region’s data center boom. From Kulai to Johor Bahru, and from Johor straight into Singapore, our network is engineered specifically for the kind of demanding, mission-critical traffic that AI and cloud workloads now generate. What sets us apart isn’t just reach it’s reliability you can hold us to. Every route we deliver in Johor is backed by committed Service Level Agreements (SLAs), ensuring your workloads are carried with the uptime, latency, and performance guarantees you’d expect from infrastructure powering AI training, cloud availability zones, and 24/7 enterprise operations. When you run on DCConnect in Johor, your traffic isn’t just connected — it’s delivered with the consistency and excellence your business depends on. If your roadmap touches Johor’s data center boom, whether you’re expanding into STeP, anchoring AI workloads at YTL, deploying in JHB1, or interconnecting across the corridor into Singapore DCConnect is the connectivity partner built to carry it.
