As data becomes a core organizational asset, compliance can no longer stop at where data is stored. New regulations signal a clear shift, from meeting data residency requirements to governing the entire data lifecycle.
At the beginning of 2026, Vietnam’s Personal Data Protection Law No. 91/2025/QH15 came into effect, establishing a new legal framework for the collection, processing, and protection of personal data throughout its lifecycle. Decree No. 53/2022/ND-CP had previously introduced in-country storage requirements for certain categories of data and businesses within its scope.
For banks, financial institutions, and the public sector, the value of cloud is measured not only by speed or scalability, but also by its ability to answer three fundamental questions: Where does the data reside? How is it processed and protected? Who is accountable for maintaining control?
AWS Local Zone Hanoi gives organizations another infrastructure option for addressing these questions. Yet the Local Zone is only the foundation. Turning infrastructure capabilities into a system that can be deployed, governed, and operated over the long term requires organizations to begin with their business, data, and legal requirements. This is the gap TechX addresses as an AWS consulting and implementation partner.
AWS Local Zone Hanoi unlocks three layers of enterprise value
AWS recently launched AWS Local Zone Hanoi as an extension of the AWS Asia Pacific (Singapore) Region, bringing selected compute, storage, and networking services closer to businesses and end users in Vietnam. The Local Zone can support end-user applications with latency below 10 milliseconds, while also serving workloads with in-country data residency requirements and selected AI/ML inference use cases.
The significance of AWS Local Zone Hanoi, however, extends well beyond faster response times. According to Mr. Ngo Manh Ha - CEO of TechX, the infrastructure unlocks three distinct layers of value for enterprises.
More options for storing and processing data in Vietnam
Organizations can store or back up data in Vietnam while retaining consistent operating models, APIs, toolsets, and security capabilities across the AWS ecosystem. This provides a stronger foundation for meeting data residency requirements without building an entirely separate technology environment.
Before AWS Local Zone Hanoi became available, some organizations had to maintain dedicated on-premises infrastructure for local data storage or backup while running other application layers in the cloud. This parallel model increased both capital expenditure and operational overhead.
For workloads that can meet their data residency, performance, and service requirements on the Local Zone, organizations may gradually reduce the on-premises infrastructure maintained primarily for local data storage. AWS reports that customers migrating legacy applications to AWS achieve an average of 31% in infrastructure cost savings through the AWS Migration Acceleration Program. This figure is a program-wide benchmark, not a guaranteed saving specific to AWS Local Zone Hanoi. TechX must still evaluate the business case for each workload based on its full investment, operating, and staffing costs.
Connecting existing systems to modernize in phases
AWS Local Zone Hanoi does not force organizations into a binary choice between keeping every system in the data center and moving everything to the cloud. Its value lies in enabling workloads to be placed more flexibly according to each organization’s data, performance, and operating requirements.
Mr. Ngo Manh Ha explained: “AWS Local Zone Hanoi enables data residency without requiring organizations to abandon their established operating model or the familiar AWS toolchain. More importantly, it creates a practical foundation for a hybrid roadmap: core systems can remain in the data center, while suitable workloads are modernized incrementally on AWS.”
To translate this roadmap into execution, TechX assesses system dependencies, classifies workloads, and determines which components should remain in the data center and which are suitable for the Local Zone. AWS Direct Connect provides private, low-latency connectivity between the two environments.
From there, TechX works with the organization to select priority applications for a pilot, validate performance and operational readiness, and expand only when the defined criteria have been met. Modernization can therefore proceed through controlled phases rather than a single, enterprise-wide cutover.
Running sensitive data and AI workloads in Vietnam
Beyond providing another option for in-country data storage, AWS Local Zone Hanoi enables organizations to run sensitive and performance-intensive workloads in Vietnam.
“With next-generation compute capabilities such as C7i, M7i, and R7i, together with object storage and container services including Amazon ECS and Amazon EKS available in Vietnam, organizations can run workloads that process sensitive data locally. From financial transactions to AI applications, suitable workloads can meet data location requirements while maintaining performance comparable to other AWS Regions.”
With compute and storage capabilities deployed in AWS Local Zone Hanoi, organizations gain additional architectural options for financial transaction processing, sensitive data analytics, and AI inference. The shift is significant: for suitable workloads, data can now be processed, not merely stored, within Vietnam.
Not every application, however, can be moved to the Local Zone unchanged. TechX evaluates data sensitivity, performance requirements, system dependencies, and the AWS services involved. It then determines which components are best deployed in Hanoi and which should remain in the data center or the AWS Singapore Region.
Data residency is necessary, but not sufficient for compliance
Storing data in Vietnam is an important part of compliance, but it does not address the full obligation.
Vietnam’s Personal Data Protection Law No. 91/2025/QH15 governs the entire personal data lifecycle. Its requirements cover the legal basis for processing and consent; data subject rights; impact assessment records for data processing and cross-border personal data transfers where applicable; the appointment of responsible teams and personnel; access controls; and incident response obligations. Decree No. 53/2022/ND-CP, meanwhile, focuses on in-country data storage requirements for the data categories, businesses, and circumstances within its scope.
In other words, an organization may store data in AWS Local Zone Hanoi and still fall short of compliance if it lacks an appropriate legal basis for collection, cannot control who has access, or cannot demonstrate how the data has been processed and shared.
“Infrastructure answers the question, ‘Where does the data reside?’ Compliance answers a broader set of questions: ‘How is the data collected, processed, shared, and protected and who is accountable?’ AWS Local Zone Hanoi is an important prerequisite, but it is not sufficient on its own to ensure compliance.”
Rather than moving all data to the Local Zone and treating the matter as resolved, organizations must understand their data, identify the obligations that apply, and translate each requirement into a specific control.
Techx as the two-way translator between legal requirements and cloud architecture
The legal framework defines what an organization must comply with, but it does not prescribe how those requirements should be implemented in the technology stack. The challenge lies in translating data regulations into concrete decisions about architecture, access, and control.
As Vietnam’s first AWS Premier Tier Services Partner, with extensive implementation experience in banking and financial services, TechX translates the requirements of Personal Data Protection Law No. 91/2025/QH15 and Decree No. 53/2022/ND-CP into specific technical designs:
Classify and map data: Determine which data must be stored or processed in Vietnam, which data can use services in the AWS Singapore Region, and which data flows require additional restrictions, encryption, or assessment.
Place workloads according to actual requirements: Select the appropriate components for AWS Local Zone Hanoi, the AWS Singapore Region, the existing data center, or dedicated infrastructure based on compliance, performance, resilience, service availability, and cost.
Build controls in from the outset: Establish a Landing Zone with guardrails for data location, access control, encryption, key management, logging, monitoring, backup, and recovery. Audit trails enable organizations to trace activity and provide evidence for audits or regulatory inquiries.
Validate and maintain compliance continuously: TechX pilots priority workloads before scaling. After go-live, its managed services capabilities help organizations monitor configurations, access rights, security events, and the ongoing effectiveness of controls.
This approach enables organizations to balance compliance, performance, resilience, cost, and speed of innovation, without moving every workload to the Local Zone or maintaining cross-border data architectures without clear visibility into data flows.
Expanding the Deployment Options for Xora Agentic AI Factory
The principal barrier to adopting AI agents in banking and the public sector is not technology alone. Organizations must also determine where training, context, and conversational data reside; who can access them; which actions an agent is authorized to perform; and whether its decision-making process can be traced.
AWS Local Zone Hanoi creates the opportunity for TechX to deploy Xora’s end-to-end AI agent lifecycle in Vietnam, from the data layer and orchestration layer to the agent execution layer on AWS infrastructure operated in accordance with global security standards. This gives Xora Agentic AI Factory a stronger foundation for deployment in sectors with stringent data location, security, and compliance requirements.
For banking and financial services, this architecture broadens the scope for use cases such as AIOps monitoring for core systems, internal operations agents, customer data analysis assistants, and workflow automation involving sensitive data. In the public sector, greater control over data location and data flows provides another architectural option for organizations with stringent governance requirements.
“AWS Local Zone Hanoi gives Xora an additional architectural answer for AI agent use cases that were previously constrained by requirements to keep data within Vietnam. TechX’s direction is to build a spectrum of deployment options, from the Local Zone to dedicated infrastructure models such as AWS Outposts so that each organization can find the right balance between data control, cost, and speed of innovation,” said Mr. Ngo Manh Ha.
Under this approach, TechX can combine AWS Local Zone Hanoi and AWS Outposts to deploy Agentic AI Factory in Da Nang, where TechX has established its new Cloud and AI operations center. Organizations can therefore choose between an AWS-operated Local Zone with data residency controls and dedicated AWS Outposts infrastructure, depending on their compliance, cost, and innovation requirements.
AWS Local Zone is the foundation; value comes from how it is implemented
AWS Local Zone Hanoi adds an important building block to Vietnam’s cloud, data, and AI landscape. Yet data residency creates business value only when it forms part of an integrated architecture with clear workload placement principles, end-to-end data controls, and continuous operations.
With its capabilities across cloud, data, AI, and Security, Governance & Compliance, TechX helps organizations move from legal and business requirements to an AWS architecture that can be implemented in practice. Xora Agentic AI Factory extends that value by enabling customers to introduce AI agents into critical processes in a controlled, traceable, and accountable manner.
