Modernising a Customer Reviews Service for Ecommerce

Customer reviews were an important part of the ecommerce experience, helping shoppers build confidence in products before buying. The existing reviews service worked, but it had been built before the wider platform moved toward a cloud-native AWS architecture. Over time, that created unnecessary friction. The service used a different deployment model, sat outside the platform's newer security boundaries, and required separate handling whenever it needed to change. That made a relatively simple customer-facing feature more awkward to maintain than it needed to be. The goal was not to redesign the reviews domain from scratch. The existing data model still worked. The priority was to preserve the behaviour the business relied on while bringing the service into the same operational model as the rest of the platform.

The reviews service now runs like the rest of the platform. It uses the standard deployment pipeline, follows the same security model, and can be maintained by the client's team without special-case handling. For the business, the value was operational stability around a customer-facing feature. Reviews remained part of the buying journey, but the service behind them became easier to change, easier to deploy and easier to support. The rebuild removed an architectural outlier and gave the client a cleaner foundation for future ecommerce improvements.
