Deploying Workloads and Compute in Singapore, Malaysia, and Thailand: How to Interconnect China and Southeast Asia?

Why interconnection demand is increasingly concentrated around Singapore, Johor, and Bangkok

In recent years, as power and land supply for local data centres in Singapore has tightened, neighbouring Johor in Malaysia and Bangkok further north in Thailand have rapidly absorbed substantial new data centre and compute construction, making the Singapore–Johor–Bangkok belt a major hotspot corridor for data centre and compute interconnection in the Asia-Pacific region.

In practical deployments by Chinese enterprises expanding overseas, an increasingly common architecture places external gateways or regional headquarters systems in Singapore while hosting expanded business servers, disaster recovery environments, development and test platforms, or compute nodes in Johor or Bangkok, all linked back to domestic R&D centres and the headquarters internal network. In daily operation, this cross-region architecture typically faces two network challenges:

• Despite close physical distance, cross-border paths over the public internet are prone to detours and congestion: Although mainland China and cities across Southeast Asia are both in Asia, international egress links across different carriers on the public internet often become congested during evening peak hours or link fluctuations, and packets sometimes detour through other regions—causing higher latency and intermittent connections that impair remote operations response and real-time API calls.
• Mixed traffic types cause large file transfers to crowd out daily interactive sessions: Domestic teams need real-time access to admin consoles, databases, and code environments in Southeast Asia data centres or clouds while also regularly pushing release packages overseas, synchronising production data, or sending back backup files. When all of this traffic runs together over standard public internet broadband, bulk data synchronisation easily crowds out daily backend operations and remote connections, making them laggy and unresponsive. (If your primary scenario involves connecting multi-site GPU clusters, pulling open-source large models, and running remote algorithm development, see How Enterprises Can Build a Dedicated Compute Network Connecting Multi-Site GPU Nodes and R&D Teams.)

Connect to the nearest PoP along the China–Southeast Asia corridor using existing broadband for bidirectional transmission

To meet interconnection needs between China and the Singapore, Johor, and Bangkok region, we provide cross-region and cross-border enterprise infrastructure interconnection services that help enterprises connect both ends without modifying application software:

• Connect to the nearest PoP along the corridor to reduce cross-border public internet detours: We cover the connectivity corridor between China and Southeast Asia (spanning Singapore, Johor, and Bangkok). Domestic offices and data centres as well as Southeast Asia sites along this corridor can connect to the nearest PoP on the corridor, with our cross-region transmission channel handling stable transmission across the cross-border segment. For other countries or regions outside this connectivity corridor, we will confirm access conditions with you in a formal proposal after reviewing your specific site locations.
• Use existing broadband at both ends for faster provisioning and on-demand bandwidth scaling: Both domestic and Southeast Asia sites can connect to our cross-region transmission channel directly over their existing local broadband links to the public internet, without waiting for lengthy cross-border physical dedicated line construction, achieving faster provisioning than traditional carrier dedicated lines. As your Southeast Asia workloads expand, R&D headcount grows, or data synchronisation volume increases, channel bandwidth can be adjusted on demand at any time.
• Bidirectional support for daily office access, R&D collaboration, and bulk data transfers: The channel fully supports TCP, UDP, and HTTP(S) protocols, carrying both daily interactive traffic—such as domestic teams accessing Southeast Asia business systems and running remote operations and debugging—and bulk data synchronisation, disaster recovery replication, and large file transfers between the two regions, with full support for bidirectional access and connection initiation from either side.
• Optional appliance and path high availability for critical sites: For sites handling core production transactions, critical compute scheduling, or headquarters hub functions, you can opt for dual-appliance high availability and transmission path high availability to reduce the risk of downtime from a single device or single local broadband failure (for configuration details, see our cross-border and multi-site network redundancy guide).

How local resources and cross-region transmission are divided, and what to prepare for your initial consultation

When setting up Southeast Asia nodes, many enterprises do not have network engineers stationed overseas and want to know how both sides coordinate implementation. In actual delivery, the division of responsibilities is straightforward:

When reaching out for a consultation, you do not need to troubleshoot cross-border routing on your own first or prepare complex network topology diagrams or packet capture reports in advance. For our initial discussion, simply let us know which domestic offices or data centres are involved, which cities host your Southeast Asia sites (and whether they are public clouds, colocation data centres, or offices), and the main business operations running between the two regions, and we can evaluate a suitable access approach for you. Because data centre and local broadband conditions vary across cities, specific network performance metrics, SLA terms, and pricing will be confirmed with you item by item in a formal proposal based on actual network conditions at each site.
