A colocation provider gives your business a safe place for your servers. However, it does more than give you space. Beyond that, it provides the power, cooling, security, and network links that keep your systems running. In fact, CBRE, Global Data Center Trends 2026 reported that global data center vacancy stayed low in 2026. At the same time, power supply remained limited, which slowed new capacity growth in major markets.
As a result, you should look beyond the size of a building. Instead, a good data center needs enough power, strong connections, and the flexibility to grow alongside your business.
What defines an advanced colocation provider?
More importantly, an advanced colocation provider keeps your business running well now, while also preparing you for what comes next. To do that, it should offer steady power, open space, and strong connections. At the same time, it should give you room to grow. JLL, 2026 Global Data Center Outlook expects global data center capacity to almost double between 2026 and 2030. As a result, cloud services, AI, and digital businesses are driving this growth.
At the same time, a modern facility must also be able to handle heavier workloads. AI and other advanced tools need more computing power, which in turn puts more pressure on power and cooling systems. In fact, Uptime Institute, Global Data Center Survey 2025 found that data center operators still face problems with power supply, costs, and upgrades.
Because of this, you should look closely at what a colocation provider gives you before you pick one.
What are Hyperscalers vs. Colocation?
A hyperscaler builds and runs its own large data centers. Meanwhile, a colocation provider lets you use shared data center space while you keep full control of your own servers and gear. While both models help you grow online, they give you different levels of control, choice, and fit for your needs. In fact, JLL, 2026 Global Data Center Outlook expects both hyperscale and leased data center space to keep growing through 2030.
| Category | Hyperscale | Colocation |
| Ownership and control | Run by the operator | Customer controls their own equipment |
| Facility design | Built for one company’s needs | Built for many customers |
| Flexibility | More fixed | More open to change |
| Connectivity options | Focused on its own network | Access to many networks |
| Expansion | Adds large-scale capacity | Adds space, locations, or services |
| Best for | Large, steady workloads | Companies with hybrid cloud and multi-location needs |
Still, these two models are not an either-or choice. In fact, many businesses use both. For example, they may pick a colocation provider for its open, flexible fit and direct links, while at the same time running steady workloads on a hyperscale platform.
Why does connectivity matter in colocation?
Connectivity matters in colocation because your systems need to talk to the world around them. In practice, a colocation provider does not work alone. Instead, your servers often need to reach cloud platforms, business partners, offices, customers, and other data centers. As a result, connectivity has become an important part of the colocation environment. S&P Global, 2026 Trends in Data Center Services & Infrastructure points to connectivity as a key part of the data center market.
With that in mind, picking a colocation provider is not just about where your servers sit. More importantly, it is also about how easily your data can move between places.
A strong connectivity setup can give you:
- More network choices: Connect with different network providers.
- Better reliability: Multiple routes mean you rely less on just one connection.
- Private connections: Link locations without relying only on the public internet.
- Easier cloud access: Direct links make it easier to reach cloud services.
- Simpler expansion: Your locations work together more smoothly.
As your connectivity needs keep growing, a good colocation provider keeps upgrading its gear to match.
Why is power density changing colocation?
Power density is changing colocation because modern tech uses much more power than older systems. As a result, AI, cloud computing, and high-performance tools need stronger systems to run well. In fact, Uptime Institute, Global Data Center Survey 2025 reported that higher-power gear keeps becoming more common as businesses take on heavier workloads.
At the same time, more power also means more heat. Because of this, a colocation provider needs better cooling to keep your gear safe. Meanwhile, S&P Global, 2026 Trends in Data Center Services & Infrastructure found that more companies are trying out liquid cooling as rack power needs keep going up.
Ultimately, for your business, the question is simple. Can the facility support the tech you may need later?
How does colocation support multi-site growth?
A colocation provider supports growth across many sites by helping you expand into new facilities, cities, or regions without building everything from scratch. As a result, you can add capacity, enter new markets, and build a stronger setup. In fact, JLL, 2026 Global Data Center Outlook expects leased data center space to keep growing through 2030.
At the same time, many locations only work well when they can communicate with each other effectively. That’s why strong links between facilities are essential for moving data quickly and keeping things running smoothly.
How does connectivity extend beyond the data center?
Dedicated fiber takes connectivity beyond a colocation provider by creating private links between data centers, network hubs, and your key business locations. As a result, this helps you connect different parts of your setup as you grow.
This is where ARNet fits into a wider colocation plan. ARNet provides dedicated dark fiber links across Southeast Asia, helping businesses build reliable connections between important locations. For example, its Dark Fiber solution offers dedicated fiber links, while its regional network connects key locations across the region.
Ultimately, for businesses building digital systems across Southeast Asia, the data center is only the bigger picture. By pairing the right colocation provider with dedicated fiber links, you can build a stronger network that is ready for future growth.
