Indonesia, 2021. Amazon Web Services opens a full cloud region in Jakarta, plants its flag in the world’s fourth most populous nation, and declares itself essential infrastructure for the archipelago’s digital economy. Alibaba Cloud had been there since 2018. Three years head start. And AWS still walks in and immediately becomes the preferred vendor for Tokopedia — Indonesia’s largest e-commerce platform. How does that happen?
That answer tells you more about the cloud war in Southeast Asia than any market share chart.
Southeast Asia’s cloud market was worth approximately $15B in 2024 and is projected to reach $40B by 2030. This isn’t server capacity being debated — it’s who controls the digital backbone of a region with 700 million people, the fastest-growing middle class on earth, and six of the top twenty emerging-market digital economies. Every bank, every e-commerce operator, every government digitisation project, every startup raising Series B capital needs to make a cloud infrastructure decision. That decision shapes vendor lock-in cycles of 5–10 years. The providers winning these deals now are building moats that will compound for the rest of this decade.
AWS moved first in Southeast Asia in 2010 with its Singapore region. Alibaba Cloud opened Singapore in 2016. The six-year gap gave AWS time to build the regional partner ecosystem — integrators, DevOps talent pools, certification programmes — that makes switching costs prohibitively high for enterprises once embedded. IDC data as of 2024 puts AWS at approximately 32% APAC cloud market share. Alibaba Cloud globally is #4, behind AWS, Microsoft Azure, and Google Cloud. In Asia Pacific specifically, AWS leads comfortably. The question is whether “Alibaba is behind” is the whole story. It isn’t.
AWS’s dominance in non-China ASEAN has less to do with product parity (the technical capabilities are largely comparable at the infrastructure level) and more to do with origin of capital. When a Southeast Asian startup raises from US VCs, the term sheets often specify AWS credits as part of the package. When a Philippine bank hires McKinsey to design its core banking modernisation, the recommendation comes with AWS Activate Partnership in the appendix. The network effects of US capital flows into the region carry AWS as infrastructure by default.
Alibaba Cloud’s natural customers are Chinese companies expanding into Southeast Asia and businesses already embedded in the Alibaba commercial ecosystem: Taobao sellers building regional logistics, Lazada operators running on Alibaba infrastructure, Cainiao supply chain customers, Ant Financial partners. This is a genuinely large addressable market — there are an estimated 300,000+ Chinese-owned SMEs operating across SEA — but it’s a specific market, not a general-purpose one.
The Indonesia case is the clearest illustration. Lazada, operating in Indonesia, Singapore, Malaysia, Thailand, Philippines, and Vietnam, runs on Alibaba infrastructure — logical, since Alibaba owns it. Tokopedia, which merged with Gojek to form GoTo in 2021, is a major AWS customer. These are the two largest e-commerce platforms in Indonesia by transaction volume. They are literally on different cloud stacks. The market hasn’t converged. It has bifurcated along the lines of capital origin.
Indonesia’s Personal Data Protection Law — officially PDP Law, effective October 2024 — requires that personal data of Indonesian citizens be stored within Indonesian territory. This is the most significant regulatory development in regional cloud since Singapore’s MAS Technology Risk Management guidelines of 2021. Both AWS and Alibaba Cloud responded by building local data centre capacity: AWS Jakarta (operational 2021), Alibaba Cloud Indonesia (operational 2018, expanded 2022–2024).
The PDP Law’s effect isn’t to choose a winner. It raises the compliance cost for any cloud provider that doesn’t have an in-country region, which effectively closes the market to tier-2 providers (Oracle, IBM, Huawei Cloud) for any regulated industry use case. AWS and Alibaba Cloud both clear this bar. Google Cloud, which opened a Singapore region but has been slower on Indonesia-specific infrastructure, is building to catch up.
For enterprise buyers — banks, telcos, healthcare companies, government agencies — local data residency is now a procurement requirement, not a preference. That benefits the two providers who built local infrastructure earliest. Alibaba Cloud’s 2018 Indonesia entry, which looked like aggressive early investment at the time, turned out to be a regulatory compliance moat before the regulation existed.
Thailand is AWS country with a complication. AWS opened Bangkok in 2022. The Thai government’s digital economy push — Government Cloud (G-Cloud) — uses AWS as a tier-1 provider. Alibaba Cloud opened Thailand in 2022 as well, largely targeting Chinese tourism infrastructure companies and regional Alibaba supply chain participants. AWS has the wider Thai enterprise footprint. Alibaba Cloud has the Chinese business community in Thailand — which, given that Thailand hosts one of the largest ethnic Chinese diaspora populations in ASEAN, is not a small addressable market.
Malaysia is a genuine contest. AWS opened Kuala Lumpur in 2024 — later than most SEA peers. Alibaba Cloud launched Malaysia in 2023. Both arrivals are recent, which means both are competing for the same enterprise migrations simultaneously. Malaysia Digital Economy Corporation (MDEC) has signed MoUs with both providers. The Malaysian government is actively using cloud vendor competition to negotiate better pricing and data sovereignty terms. This is smart procurement. Malaysia will likely end up with a multi-cloud government stack, which is the outcome both AWS and Alibaba Cloud will publicly endorse and privately consider a partial loss.
Vietnam and Philippines are AWS-heavy markets, largely due to US capital flows into both economies’ startup ecosystems and the US military-commercial relationship in the Philippines. Alibaba Cloud’s presence in both markets is growing but remains primarily China-corridor focused.
There is a trust differential operating in non-China ASEAN markets that no vendor presentation will include in its slides. In Singapore, Philippines, Malaysia, and Vietnam — all nations with active US security partnerships or US capital market exposure — AWS carries a “trusted partner” designation that Alibaba Cloud does not. This doesn’t mean enterprises won’t use Alibaba Cloud. It means that for sensitive workloads — financial data, government services, health records — the default recommendation from consultants, regulators, and security teams is US cloud infrastructure.
This isn’t irrational. It’s geopolitical risk management. And it’s a structural ceiling on Alibaba Cloud’s total addressable market in the non-China, non-Alibaba-ecosystem segments of ASEAN. The Huawei situation — where US pressure led to effective bans in many Western-aligned markets — has created a category risk perception for Chinese tech infrastructure providers broadly. Alibaba Cloud is not Huawei. But the category association costs it enterprise deals that its product quality alone would have won.
The counter-reading: Chinese tech infrastructure in ASEAN is not declining. It is concentrating in the specific segments where it has genuine competitive advantage — China-connected businesses, price-sensitive startups, markets where US capital isn’t the dominant funding source (Cambodia, Laos, Myanmar). These aren’t vanity markets. They are where infrastructure gets embedded earliest in digitising economies.
If you are building a SaaS product for the global or US-adjacent market from a Southeast Asian base: AWS. The ecosystem, the talent availability, the VC term sheet alignment, and the compliance documentation quality all point the same direction. Use the credits, build with the most-documented APIs, hire developers who already know the stack.
If your business is building China market connectivity — cross-border e-commerce, Chinese tourist-facing services, Alibaba supply chain integration, Chinese corporate expansion into SEA — Alibaba Cloud gives you latency advantages, a native WeChat/Alipay/Ant integration ecosystem, and pricing that undercuts AWS for equivalent compute at the entry tier by 15–30%.
If you are a regulated enterprise (bank, insurance, healthcare) in Indonesia, Malaysia, or Thailand: you need a local region with in-country data residency. Both providers now qualify. The decision comes down to your consultants’ biases and your procurement team’s supplier diversity requirements. Neither answer is wrong.
The infrastructure war in Southeast Asia isn’t over — it’s entering its most commercially intense phase. The next five years will see every major ASEAN economy build out digital government services, national health data systems, central bank digital infrastructure, and e-procurement platforms at scale. These are decade-scale contracts. AWS is better positioned for the majority of them. But Alibaba Cloud will win a meaningful share — particularly in markets where China is the dominant trade partner, and particularly in verticals where the Alibaba commercial ecosystem creates genuine integration advantages.
The more interesting story may not be AWS vs Alibaba at all. It may be whether either can hold off Huawei Cloud, which is building SEA infrastructure quietly and pricing aggressively in markets where the US trust deficit doesn’t apply. Indonesia’s infrastructure ministry has already signed agreements with Huawei for non-cloud connectivity projects. The cloud follow-on is not far behind.
By 2028, Southeast Asia’s cloud market will have a clearer map. Right now, it has a frontier — and the capital flowing in to claim it is the most consequential infrastructure investment in the region’s digital history. Watch where the government procurement dollars go. That’s where the winner gets confirmed.
