Digital Realty has begun providing colocation infrastructure to Samsung Electronics at its ICN10 facility in Seoul, a deal that highlights how large corporate users in South Korea are seeking more resilient, high-density digital infrastructure as artificial intelligence, cloud services and mission-critical enterprise workloads put heavier demands on power, cooling and connectivity. The announcement was made on March 25 by Digital Realty, which said the arrangement would support Samsung Electronics’ enterprise IT operations from its Seoul site.
The ICN10 facility, located in Sangam-dong in Mapo-gu, has been operating since 2022 and is described by the company as South Korea’s first carrier-neutral data centre. Digital Realty says the building has a maximum IT load of 12 megawatts and around 132,000 square feet of space, with high-density power architecture, network connectivity and the resilience needed for large-scale computing environments. Those specifications matter because enterprise clients are no longer looking only for secure rack space; they increasingly want facilities that can handle denser compute loads without compromising uptime.
For Samsung Electronics, the move points to a practical shift in how even large technology groups manage parts of their own internal infrastructure. Rather than relying exclusively on self-operated facilities, major companies are turning to specialist operators for colocation capacity that can be scaled more quickly and managed to global standards. Digital Realty framed the arrangement as support for a large-scale customer environment in Korea, while emphasising stable, high-performance infrastructure for global enterprises. That wording suggests the deal is less about consumer-facing products and more about the backbone systems that keep a multinational company running across data-intensive operations.
The timing is notable because Seoul’s data-centre market is expanding while facing mounting strain over where future capacity can be built and how it will be powered. Cushman & Wakefield said the Greater Seoul Area reached 533 megawatts of capacity in the first half of 2025, with a further 715 megawatts in the development pipeline, alongside land secured for another 250 megawatts. Its later market update said the second half of 2025 saw double-digit year-on-year growth, while AI demand and tighter power-related rules were reshaping development patterns. That combination of growth and constraint is pushing operators and customers alike to value operational certainty.
South Korea’s broader technology push adds another layer to that demand story. Reuters reported this week that Seoul approved a 250 billion won investment in AI chip startup Rebellions, part of a wider effort to strengthen domestic semiconductor and advanced computing capabilities. Reuters also reported that SK Hynix is pursuing a US listing partly to fund major chipmaking investments tied to rising AI demand. Those moves sit outside the colocation market itself, but they reinforce the same structural point: processing power, data movement and digital infrastructure are becoming more strategically important across the economy.
Digital Realty’s position in Seoul also reflects a larger contest among global and regional operators seeking to capture Asia’s enterprise and cloud demand. Market research and adviser reports point to South Korea as one of the faster-growing data-centre markets in the region, driven by digital-first consumers, cloud adoption and increased enterprise modernisation. JLL’s 2026 outlook said the global data-centre sector could nearly double between 2025 and 2030, while other market estimates show South Korea’s colocation and broader data-centre segments expanding strongly through the decade. Forecasts from commercial research firms should be treated cautiously, but taken together with operator activity and land acquisition trends, they show why Seoul has become a closely watched infrastructure market.
The Samsung agreement may not be transformative in size on its own, yet it carries signalling value. When one of the country’s largest technology groups places enterprise workloads with an external colocation provider, it gives weight to the argument that carrier-neutral, high-density facilities are becoming integral to mainstream corporate IT strategy rather than serving only cloud giants and telecom operators. It also strengthens Digital Realty’s credentials in a market where network diversity, reliability and location all matter.
Questions remain over how quickly South Korea can add capacity in and around Seoul without worsening power bottlenecks or pushing new builds further from the capital’s main concentration of corporate demand. Legal and advisory analyses have pointed to the mismatch between the location of generation capacity and the heavy concentration of data centres around metropolitan Seoul. That tension is likely to shape the next phase of expansion, forcing operators to balance geography, power access and customer proximity more carefully than before.
