TL;DR:<\/strong> The AWS Local Zone Hanoi went live on June 19, 2026, bringing single-digit millisecond latency and in-country data processing to Vietnamese enterprises. For companies using DataCore's Address Service, eKYC Service, and Company Intelligence Service, the Local Zone means faster API responses and a cleaner path to data-residency compliance under Decree 13\/2023\/ND-CP. This post covers what this AWS infrastructure is, why it matters for regulated industries in Vietnam, and what it means for data-driven businesses building on Vietnamese data infrastructure today.<\/p>\n\n\n\n

What Is the AWS Local Zone Hanoi and How Does It Work?<\/h2>\n\n\n\n

The AWS Local Zone Hanoi is an extension of Amazon Web Services' Singapore Region (ap-southeast-1), deployed on physical infrastructure located inside Vietnam. Unlike the full AWS Regions in Singapore or Tokyo - which are multi-availability-zone deployments with over 200 managed services - the Hanoi's Local Zone is a smaller, purpose-built compute and storage presence designed for latency-sensitive workloads. When a Vietnamese enterprise deploys an application to this in-country deployment, the data processing happens inside Vietnam, not in a neighboring country's data center.<\/p>\n\n\n\n

AWS operates more than 35 Local Zones globally across 6 continents. The AWS Local Zone Hanoi joins Local Zones already serving Bangkok, Manila, Taipei, and other Southeast Asian cities. Each Local Zone extends its parent AWS Region while keeping the most latency-critical services - compute, storage, networking, databases, and caching - physically close to end users. For Hanoi-based applications, the Local Zone in Hanoi reduces round-trip latency from the 30-50ms typical of a Singapore routing path to under 10ms for workloads running locally.<\/p>\n\n\n\n

The AWS Local Zone Hanoi supports the following core services at launch: Amazon EC2 (compute instances), Amazon EBS (block storage), Amazon VPC (virtual private networking), Amazon RDS (managed relational databases), Amazon ElastiCache (in-memory caching), Amazon FSx (file storage), and Application Load Balancers. Organizations already using the Singapore Region can extend their existing VPC to include this AWS extension without rebuilding their architecture - a significant operational advantage over standing up an entirely new region footprint.<\/p>\n\n\n\n

Connectivity between the AWS Local Zone Hanoi and the parent Singapore Region runs over AWS's dedicated global backbone, not the public internet. This means that data movement between Hanoi-local resources and Singapore-based services such as Amazon S3, Amazon CloudFront, or AWS Lambda benefits from low-latency, high-reliability dedicated links rather than unpredictable internet routing. Enterprises can therefore run a split architecture: latency-sensitive or compliance-critical workloads run in the new Local Zone, while storage, analytics, and services without residency constraints remain in Singapore.<\/p>\n\n\n\n

Why the AWS Local Zone Hanoi Launch Matters for Vietnamese Enterprises<\/h2>\n\n\n\n

Before the AWS Local Zone Hanoi, Vietnamese enterprises had three choices for cloud infrastructure: use a hyperscaler region in Singapore or Tokyo and accept the latency and residency trade-offs; contract with a local Vietnamese cloud provider such as Viettel Cloud or FPT Cloud; or build and operate their own data center infrastructure. None of these options was ideal. The Singapore-based hyperscaler path offered superior service breadth but introduced cross-border data flows. Local Vietnamese cloud providers offered in-country presence but often lagged on managed service capabilities. On-premises infrastructure was expensive to build and operate at scale.<\/p>\n\n\n\n

The AWS Local Zone Hanoi changes this picture substantially. Vietnamese enterprises can now run workloads on world-class managed infrastructure - with AWS SLAs, security certifications, and the global AWS service ecosystem behind them - while keeping compute and primary data storage inside Vietnam. For regulated industries in particular, this combination is transformative. The following three sectors stand to benefit most immediately from AWS's Hanoi infrastructure:<\/p>\n\n\n\n
