Singapore is known as the best place in the Asia-Pacific region to set up a data center because it has a stable government, great internet access and a business-friendly climate. As the country moves forward with its Smart Nation projects, the need for data center services keeps growing. Building and running their facilities is too expensive and complicated for many businesses. This is why colocation, which is renting space for servers and other hardware in a third-party facility, is a strategic necessity.
The value of the data center market in Singapore was $3.25 billion in 2025 and is expected to reach $5.11 billion by 2031, with a compound annual growth rate (CAGR) of 7.83%. This growth is due to the use of cloud technologies. By 2030, wholesale colocation is expected to make up more than 67% of revenue. The government’s push for sustainability is also changing the future of the industry by including the construction of a 700 MW low-carbon data center park on Jurong Island.
This list shows five of the top colocation providers for data centers that have a strong presence in Singapore. We compiled it using market reports from companies such as ResearchAndMarkets.com and Cushman & Wakefield. It takes into account things like market leadership, portfolio size, infrastructure quality (Tier standards) and a company’s dedication to innovation and sustainability.

How to choose the right colocation provider for data centres in Singapore
To begin, please consider your plans for growth and scale. If you only need one rack, a company like Equinix that has many retail options is a good choice. If you think you’ll need many racks or a whole suite, you should look into providers like Digital Realty or AirTrunk that specialize in wholesale.
Second, think about how much connectivity you need. Businesses that need to connect to many cloud providers, partners and networks need a carrier-neutral facility with many options, like those offered by Equinix or STT GDC.
Third, think about power density and how long it will last. You need a provider that can handle high-density racks (like 20 kW+) if you are running AI or high-performance computing workloads. Check that they follow Singapore’s strict energy efficiency rules (PUE of 1.3 or lower) and that they are committed to using green energy.
Fourth, check for compliance and geographic redundancy. Ensure that the provider has distributed their facilities to support disaster recovery plans. Most importantly, make sure they have the right certifications, such as ISO 27001, PCI DSS, SOC 2 and MTCS Tier 3, which are required for businesses that are regulated.
Finally, you should know how much it will cost to own it. Colocation is a viable option because it doesn’t require a lot of money to build a data center. However, it’s important to compare pricing models, power costs (which were reported to be USD 0.21–0.24 per kWh in Q1 2025) and any extra fees for cross-connects and remote hands services.
Singapore is the best place in APAC for data centers because it has world-class providers that offer a wide range of services to meet the needs of different businesses. Equinix provides an unrivaled interconnection ecosystem for building hybrid clouds. STT GDC stands as a homegrown leader with a strong focus on sustainability and scale. Digital Realty specializes in powering the largest hyperscale deployments. Keppel Data Centres leads the way with groundbreaking sustainable designs. AirTrunk is rapidly scaling to meet the demands of the world’s biggest digital infrastructure consumers.
The right choice depends on your organization’s specific requirements for scale, connectivity, power density and sustainability. We recommend engaging with shortlisted providers to tour their facilities, review their service level agreements and assess their ability to support your long-term digital strategy.
Frequently asked questions
1. What services do colocation providers for data centers in Singapore typically offer?
Providers give your servers and IT hardware a place to stay, like a single rack, a private cage, or a suite. They provide the infrastructure that supports them, such as backup power (UPS and generators), advanced cooling and physical security. Core services also include carrier-neutral connectivity options (cross-connects to networks and clouds) and remote hands support for simple tech tasks.
2. How much does colocation cost in Singapore?
Costs vary a lot depending on the space (per rack or cabinet), power use (per kW) and bandwidth. A full rack of retail colocation may cost a monthly fee, but wholesale prices are usually based on how much power the customer has agreed to pay for (per kW). The average price of electricity for businesses, which is part of the cost of colocation, was between USD 0.21 and 0.24 per kWh in early 2025.
3. How do I know if a colocation provider is reliable?
Tier III or IV certification for facility design and redundancy is one of the most important signs that uptime guarantees of 99.99% are possible. ISO 27001 (security), SOC 2 (controls) and PCI DSS (payment card industry) are all examples of industry-standard compliance certifications that show operational reliability. It’s also a good sign if you have a lot of experience working with big clients in your field.
4. Are colocation providers in Singapore suitable for small businesses?
Yes, many providers offer flexible, low-barrier entry points like quarter-rack or half-rack cabinets. This lets small businesses use enterprise-level infrastructure and connectivity without having to spend a lot of money to build their own facility. It has a set monthly cost and can grow with the business.
5. What should I prepare before engaging a colocation provider?
You should make a detailed list of all your hardware (servers, storage, networking equipment), including their physical sizes (U-size) and how much power they need (amperage/voltage). Set your needs for bandwidth, latency and growth. If you know exactly what you want to achieve with your business continuity and disaster recovery, the provider will be able to suggest the best solution.
6. How does sustainability affect colocation in Singapore?
New data centers in Singapore must meet strict standards set by the government, including using green energy and having a low PUE (power usage efficiency). The best providers are coming up with new ideas like using renewable energy sources, liquid cooling and seawater cooling. For both following the rules and reaching your own company’s environmental goals, it’s important to choose a provider that is sustainable.
