People are now more accustomed to quick, high-quality content delivery.

With 4K streaming, live gaming, and instant algorithmic feeds becoming the new norms these days, the “Content Delivery Network” (CDN) has evolved from a simple caching layer into a complex, physical infrastructure challenge. 

For streaming giants and hyperscalers, the software layer is only half the battle. 

The other half is strategic physical placement to distribute content efficiently.

What is a Content Delivery Network (CDN)?

A Content Delivery Network (CDN) is a geographically distributed group of servers that work together to provide fast delivery of Internet content.

A CDN enables the rapid transfer of assets required for loading Internet content, including HTML pages, JavaScript files, stylesheets, images, and videos. 

The popularity of CDN services continues to grow, and today, the majority of web traffic is served through CDNs, including traffic from major sites such as Facebook, Netflix, and Amazon.

The Shift to “Private” CDNs

When technologies change, so does the way we live and behave. 

While traditional public CDNs (such as Akamai or Cloudflare) are available basically everywhere, streaming giants often build their own proprietary content delivery infrastructure, such as Netflix’s Open Connect.

These private CDNs rely entirely on colocation: renting physical space, power, and cooling in third-party data centers to place their caching servers as close to the end-user as possible.

Why Colocation is Critical for CDN Performance

For a CDN to function effectively, it cannot float in the “cloud”; it must be “grounded” too.

The performance of modern streaming relies entirely on the physical infrastructure, and it must have physical facilities that offer three non-negotiable assets: 

Interconnection, Reliability, and Proximity.

1. Interconnection: the Fuel to Faster Content Delivery

In Indonesia, geography has become the primary adversity due to its archipelago. 

Serving content from a server in Singapore or Tokyo is doable, but not recommended either. Colocation provides dense interconnection ecosystems, allowing CDNs to connect directly with ISPs, carriers, and cloud providers. This eliminates unnecessary hops and dramatically reduces latency.

2. Direct Peering and Neutral Interconnection Ecosystems

Direct peering removes the middlemen between networks.

Carrier-neutral colocation facilities enable direct peering with dozens or even hundreds of networks. This ensures faster, more predictable routes for content delivery.

A CDN node is useless if it cannot talk to the local Internet Service Providers (ISPs) that deliver the “last mile” to the consumer’s home. This is why facilities like Digital Realty Bersama, which hosts APJII’s IIX-JK2 Internet Exchange, Indonesia’s largest internet exchange provider, are so valuable for CDN operators as they provide immediate access to Indonesia’s most extensive peering ecosystem.

3. Proximity: Reducing Latency Through Optimized Network Paths

CDNs perform best when data travels along the most efficient network routes.

When servers are colocated near major internet exchange points, CDNs can serve content using the shortest and most efficient routes possible, cutting round-trip time significantly.
Streaming traffic can be quite unpredictable, especially during a live sports final or a season premiere. 

Why Jakarta is the Next Hotspot for Streaming Quality

For the past years, Indonesia has been shifting its focus from a strategy of connectivity to one of sovereignty.

Indonesia is Southeast Asia’s largest digital economy, with over 200 million internet users. However, its geography with more than 17,000 islands presents a unique content delivery challenge.

For global platforms, its capital city, Jakarta, is the primary gateway. But not all Jakarta data centers are created equal. To win this market, CDNs need a facility that acts as a “meeting place” for networks, not just a storage locker for servers.

The Digital Realty Bersama Advantage

Digital Realty Bersama operates at the intersection of global standards and local connectivity. Our facilities, such as CGK11, are designed specifically to host the critical nodes of global CDNs:

1. Direct Access to IIX-JK2

Digital Realty Bersama facilitates direct connection to the Indonesia Internet Exchange (IIX-JK2).

Streaming companies colocating with us can peer directly with hundreds of local Indonesian ISPs. This drastically lowers bandwidth transit costs and ensures the smoothest playback experience for Indonesian viewers.

2. Carrier Neutrality 

Data centers such as Digital Realty Bersama have a carrier-neutral ecosystem.

You aren’t locked into a single telco. At CGK11, you can choose from over 25 network service providers, enabling you to build a redundant and resilient network mesh that guarantees 100% uptime for your viewers.

3. Global Consistency via PlatformDIGITAL®

For engineering teams managing infrastructure across 50 metros globally, consistency is key.

Digital Realty’s PlatformDIGITAL® allows you to deploy the same architecture in Jakarta as you do in the USA, London, or Tokyo. We support high-density deployments tailored for AI-driven recommendation engines and heavy video workloads.

Technical Checklist: What to Ask Your Colocation Provider

There are several requirements one must take note of when considering colocation.

Because CDN infrastructure is highly sensitive to latency, network diversity, and uptime, the data center you choose will directly influence your performance. To ensure your CDN nodes operate at peak efficiency, here are the critical questions and specifications to evaluate:

When planning to deploy a CDN node or edge cache in Jakarta, this checklist can be considered a standard to ensure the facility meets enterprise standards:

1. Uptime & Resilience

For a CDN, downtime hits much harder than a typical enterprise workload. 

A single outage can force traffic to spill over to your other PoPs, congesting them and damaging your users’ Quality of Experience (QoE). This will “turn off” their experience. Marketing labels like “Tier III” are fine, but the real question to ask is: Does this facility stay online, no matter what?

Requirements: 

• 99.999% power uptime
• Concurrent maintainability (at least Tier III Facility certified)
• 24/7 on-site engineering support
• Fast response SLAs for Remote Hands

In Jakarta, data centers such as Digital Realty Bersama’s CGK10 and CGK11 sites have consistently delivered 100% uptime so far, backed by Tier III and Tier IV design standards. 

This level of resilience is especially crucial in handling high-value traffic, where even a few seconds of downtime can be significant.

2. Interconnectivity

In Jakarta’s network landscape, location matters greatly. 

If the CDN node isn’t located near the Internet Exchange (IX), traffic may be routed across the city to reach local ISPs. This will only add latency, introducing extra failure points and slowing down user experience.

Digital Realty Bersama hosts APJII’s IIX-JK2 Internet Exchange directly inside the facility. That means your CDN node sits right next to hundreds of local ISPs, massively reducing hops and improving delivery speed.

Beyond that, DRB connects you to PlatformDIGITAL®, enabling your Jakarta deployment to integrate easily with global infrastructure. With ServiceFabric™, operators can extend and orchestrate their ecosystem across Digital Realty sites worldwide — treating Jakarta as part of a unified global network.

3. Compliance & Security: Meeting Indonesia’s Regulatory Reality

Facilities can no longer build a data center just for the sake of building it.

When choosing to colocate, Indonesia has strict laws when it comes to colocations and for the data centers themselves. These buildings must be certified properly and accordingly to official standards, or companies will not be able to colocate there. 

We have written an article highlighting what customers must consider when choosing a data center, which can be found here: Essential Data Center Certifications to Know.

The Future of CDNs 

The era of buffering is over, and it has to.

As streaming quality pushes toward 8K, as gaming becomes fully real-time, and as billions of IoT devices come online, CDNs must evolve far beyond simple content caching.

At the infrastructure level, the role of colocation will only become more important. As CDNs move toward massive edge distribution, they’ll rely heavily on carrier-neutral data centers and dense interconnection hubs to reach users efficiently. Facilities that host major exchange points, such as Digital Realty Bersama with APJII’s IIX-JK2, will serve as critical anchors in this expanding edge ecosystem.

In short, the future of CDNs will be more distributed, more intelligent, and more dependent than ever on the physical infrastructure that supports global connectivity. The CDNs that use smart technology and place their infrastructure in the right data centers will deliver the best digital experiences in the future.
