If the comparison with Singapore is about scarce capacity, the comparison between Vietnam and Indonesia in data centres (DC) is about data sovereignty. Both countries are populous, both are digitising fast, and both have written laws that pull part of their data back into onshore storage. An operator choosing where to build must therefore read the two data laws like a terrain map: where data flows freely, and where it is stopped.
Different starting points: Indonesia legislated one beat earlier
Indonesia built its electronic-systems framework early through the government regulation on electronic systems and transactions (commonly cited as GR 71/2019), which distinguishes public-sector and private-sector electronic system operators and attaches stricter data-localisation expectations to the public sector and essential services. Vietnam came later but moved toward systematisation: the Data Law 60/2024/QH15 (effective 1 July 2025) for the first time sets a unified data classification framework at statute level, separating core data and important data from ordinary data flows under their own management regime. The legislative techniques differ, but the outcome converges: sensitive data of citizens and of the state apparatus is increasingly hard to keep entirely offshore.
The Vietnam angle: data classification is the main valve
For a DC in Vietnam, the first legal question is not “may we build” but “which class of data will we hold”. Core data and important data under the Data Law 60/2024/QH15 carry stricter management, protection and transfer requirements, and the detailed catalogues of these two classes are documents an operator must cross-check before signing tenants from the public sector, finance or telecoms. Beside the Data Law, the Cybersecurity Law 24/2018/QH14 and Decree 53/2022/ND-CP continue to govern in-country storage duties for certain Vietnamese user data held by regulated businesses. On the service layer, the Telecommunications Law 24/2023/QH15 determines whether data centre and cloud services fall into a managed or licensed category. The three instruments stack into a mesh through which every tenant data flow must pass at least one screen.
The engineering certification layer is still market-led
Although the data laws differ, the engineering certification layer of DCs in both countries looks much alike, because tenants set the standard: Uptime Institute Tier ratings for redundancy, ISO 27001 for information security management, and international audit frameworks such as SOC 2 when serving foreign financial tenants. Indonesia adds a domestic-market scale advantage — more than 270 million people create a local tenant base large enough to fill the DCs around Jakarta and Batam — while Vietnam holds submarine-cable geography and lower operating costs for workloads serving northern ASEAN and East Asia. Engineering certification is therefore not the deciding variable between the two countries; the deciding variable is where the target tenant data is allowed to sit.
The Indonesia frame for comparison
When reading the Indonesian frame, an investor should hold three points as reference only. First, the public-versus-private electronic system boundary is their main classification axis, and the public sector faces markedly tighter data localisation. Second, Indonesia also has a standalone personal data protection law, stacking another duty layer on system operators. Third, special zones and the Batam area run their own DC policies tied to power supply and Singapore connectivity. All three points must be confirmed by Indonesian counsel against the instruments in force when the project runs, because that country data framework is still completing its guiding documents.
Conclusion by workload type
Workloads serving each country government and critical data are effectively locked to territory — no location debate exists for that tenant group. Regional commercial workloads (gaming, e-commerce, AI inference) are where the two countries truly compete: Indonesia wins on its giant home market, Vietnam wins on cost and its East Asia gateway. Many operators therefore choose a two-node architecture — one data-anchoring DC in each country for regulated tenants, and a regional service layer placed where costs are best — instead of betting everything on a single territory.
Frequently Asked Questions
1. What mandatory certification applies to data centres in each country, at framework level?
In Vietnam, the frame sits not in a standalone DC certificate but in data duties: classification under the Data Law 60/2024/QH15, in-country storage under the Cybersecurity Law 24/2018/QH14 and Decree 53/2022/ND-CP for regulated groups, and service management under the Telecommunications Law 24/2023/QH15; Tier and ISO 27001 are market standards. In Indonesia, the frame revolves around GR 71/2019 on electronic systems, with data-localisation expectations split between the public and private sectors.
2. Who handles quality assessment for DCs in each country, and how long does it take?
Engineering certification in both countries is performed by the Uptime Institute and independent ISO certification bodies on audit schedules the operator books, faster or slower depending on the level sought and facility readiness. Legal duties in Vietnam sit with the data, cybersecurity and telecom regulators task by task. In Indonesia, the focal points are the ministry in charge of communications and information and sector regulators. No standard duration fits every project; the plan must be broken down certification by certification and duty by duty.
3. How do EU and US standards apply to DCs in each country?
For DCs, EU and US standards arrive through tenants: European tenants require GDPR-compatible processing chains, and US financial tenants require SOC 2 audits and payment-industry security frameworks. Those duties do not change whether the DC sits in Vietnam or Indonesia. What changes is host-country data law: both countries hold data classes that may not move abroad freely, so the service architecture must split data flows by territory before international audit standards even enter the discussion.
4. How do DC compliance costs compare between the two countries?
In Vietnam, compliance spending concentrates on data-classification counsel, local-storage design for regulated tenants, Tier and ISO audits, and low operating costs. In Indonesia, spending includes data-localisation counsel under GR 71/2019 and personal-data-law compliance, in exchange for a very large home market that supports higher occupancy. Every Indonesian detail in this article is framework only — check with local counsel before deciding where to build.
