Cloud-Native Migration for E-Commerce Apps
Transitioning an on-premise e-commerce application to a cloud-native environment can seem daunting. However, with the right tools and approach, the process can be straightforward and rewarding. In this guide, we explore a practical cloud-native migration using YugabyteDB, Hasura Cloud, and Vercel, while sharing insights that can help streamline your deployment.
Understanding the Original E-Commerce Architecture
I recently explored a sample e-commerce application built with Next.js, GraphQL, and Postgres. The app includes features like product inventory, order management, a recommendation system, and checkout functionality. Naturally, I wondered how much effort it would take to move this setup from a local environment to a fully cloud-native stack.
The original architecture used on-premise components:
- PostgreSQL as the database
- Hasura GraphQL engine hosted locally
- Next.js backend and frontend served from a local server
Migrating such an application requires careful planning, especially when integrating distributed cloud services.
Lesson 1: Database Compatibility Is Critical
For a robust cloud-native deployment, you need a relational database that scales horizontally and withstands failures, such as zone-level outages. I opted to migrate PostgreSQL to YugabyteDB, a Postgres-compatible distributed SQL database.
Despite initial doubts about compatibility, the migration went smoothly after two key changes:
- Updated Docker Compose to launch a YugabyteDB container instead of Postgres.
- Adjusted the database URL in Hasura settings:
postgresql://yugabyte:yugabyte@yb-tserver:5433/yugabyte
The application started without issues, and the frontend connected seamlessly. For teams looking to deploy locally with YugabyteDB, a separate Docker Compose configuration is recommended.

Lesson 2: Switching to Cloud-Native Services Is Easier Than You Think
Replacing on-premise components with cloud-native services can save time and reduce operational complexity. In this migration, the key replacements were:
- PostgreSQL → Yugabyte Cloud
- Hasura on-prem → Hasura Cloud
- Local Next.js server → Vercel
First, I provisioned a three-node Yugabyte Cloud cluster across multiple availability zones, ensuring high resilience. Next, I deployed Hasura Cloud using the Standard Tier, which provides automatic scaling and high availability. Finally, the Next.js frontend and backend were hosted on Vercel, connecting seamlessly to Hasura via environment variables.
By adopting these services, the e-commerce app was fully operational on a cloud-native stack.

Lesson 3: Zero-Code Changes Are Rare
Although most configuration adjustments were simple, some code-level tweaks were necessary. For example:
- Updating Next.js logic to use Hasura Cloud’s admin secret correctly
- Optimizing SQL scripts for distributed transactions in YugabyteDB
The original SQL script inserted 85,000 products using individual transactions. In a distributed environment, this approach is inefficient. I replaced it with roughly 17 batch inserts, reducing the initial load time dramatically.
This highlights an important point: while cloud-native migration simplifies infrastructure management, some application-level changes are unavoidable.
Practical Steps for Your Cloud-Native Migration
To replicate this migration, follow these steps:
- Deploy locally: Set up the original architecture with PostgreSQL on your laptop.
- Transition to YugabyteDB locally: Use Docker Compose to run YugabyteDB instead of Postgres.
- Deploy to the cloud: Use Yugabyte Cloud, Hasura Cloud, and Vercel for a fully cloud-native setup.
