Vietnam's e-commerce market is one of Southeast Asia's fastest-growing, and the infrastructure demands that come with it are unforgiving. 11.11, Tet, and flash sale events can spike traffic 10x overnight. Shopee, Lazada, TikTok Shop, and your own website all need to sync in real time. We build the omnichannel cloud infrastructure that scales when it matters most.
Vietnam's e-commerce market has grown to one of the largest in Southeast Asia, with Shopee, Lazada, TikTok Shop, and Tiki collectively handling billions of dollars in annual gross merchandise value. Vietnamese consumers have embraced online shopping with remarkable speed — but this growth has exposed serious infrastructure gaps for many retailers.
The most acute problem is peak load. During 11.11, Tet promotional periods, and flash sales, traffic can spike 10x or more within minutes of an event starting. Retailers whose infrastructure can't handle this traffic lose sales, damage customer trust, and underperform competitors on marketplace algorithms. Downtime during a sale event is not just a revenue loss — it can result in marketplace penalties and ranking drops that persist for months.
Beyond peak load, omnichannel complexity adds another layer of challenge. Keeping inventory, pricing, and order data synchronised across Shopee, Lazada, TikTok Shop, your own website, and physical stores — in real time — requires robust integration architecture. FirstCloud Vietnam builds that architecture, and we have operated it through multiple peak sale events without incident.
Auto-scaling cloud architecture that expands capacity within seconds as traffic surges and scales back down after events to control costs. We design for sale-event peaks as the baseline, not the exception — with load testing against projected 11.11 and Tet traffic levels before every major commercial event.
Connect Shopee, Lazada, TikTok Shop, and Tiki to your central order management system with real-time inventory, pricing, and fulfilment status synchronisation. We build idempotent integration layers that handle API rate limits, partial failures, and marketplace-specific data formats without data inconsistencies.
Real-time synchronisation between KiotViet, MISA, Haravan, and other Vietnamese POS systems and your online channels. We ensure that when stock sells in-store, it's immediately reflected across all marketplace listings — eliminating overselling, improving fulfilment accuracy, and providing unified inventory visibility across all locations.
API integration with Vietnam's major logistics partners — GHN, GHTK, J&T, Viettel Post — for automated shipping label generation, real-time tracking, and delivery status synchronisation. We build smart order routing rules that select the optimal carrier based on destination, delivery speed, and cost for each shipment.
We document your existing e-commerce stack, integration points, peak traffic patterns, and failure modes — establishing the current-state baseline and identifying the highest-priority risks.
Week 1We architect the marketplace, POS, logistics, and CRM integration layer — designing for resilience, real-time data consistency, and the ability to add new channels without re-engineering the core.
Weeks 2–4A complete staging environment replicating production is built to enable safe testing of integrations, new features, and scaling configurations without any risk to live operations.
Weeks 4–8We simulate sale event traffic patterns — including sudden spikes to 10x normal volume — to validate auto-scaling behaviour, identify bottlenecks, and confirm that SLAs will hold under real conditions.
Week 8–9Production cutover with full observability from day one — real-time dashboards, alerting, and on-call engineering support during your first major sale event on the new infrastructure.
Week 10+Yes — this is exactly the scenario we design for. Our auto-scaling architecture uses predictive and reactive scaling policies. Before major sale events, we pre-warm capacity based on historical traffic patterns and projected campaign reach. During the event, horizontal scaling adds compute within 60 seconds of a traffic surge. We conduct full load tests simulating peak conditions before every major commercial event, so there are no surprises on the day. All our retail clients have operated through 11.11 and Tet events on our infrastructure without downtime.
Yes, we have production integrations with all three platforms, plus Tiki. We use each platform's official seller APIs for order management, inventory synchronisation, product listing management, and fulfilment status updates. For Shopee and Lazada, we're also experienced with their logistics integration APIs. All integrations include error handling, retry logic, and alerting for API failures — so you're not discovering sync issues when a customer complains about an out-of-stock order.
We build an event-driven inventory synchronisation layer that publishes stock movement events from every channel — POS sales, online orders, warehouse receipts, returns — to a central message queue. Each connected system consumes these events and updates its own records in near-real-time. This means a sale at your Da Nang store is reflected in your Shopee inventory within seconds, not hours. We've tested this architecture under high-volume scenarios without race conditions or data inconsistencies.
Yes. We have integration experience with all major Vietnamese POS systems — KiotViet, MISA, Haravan, and Sapo — as well as international platforms used in Vietnam. For systems without standard APIs, we use webhook integrations or periodic polling with conflict resolution logic. The integration covers inventory sync, order routing, customer loyalty point management, and reporting data consolidation. We can also build a unified reporting layer that shows combined online and offline performance in a single dashboard.
We enforce PCI-DSS compliance for all environments that handle payment card data. This means cardholder data is never stored in raw form in your systems — we use tokenisation with PCI-compliant payment gateway providers (VNPAY, OnePay, Stripe) and maintain a minimised cardholder data environment that reduces your PCI scope. All payment flows use TLS 1.3 in transit. We also implement fraud detection rules, 3D Secure enforcement, and transaction velocity limits to protect both your customers and your chargeback rates.
