Migrating a peak-critical e-commerce platform to AWS

The Problem

The retailer's e-commerce platform ran on ageing on-premise infrastructure that struggled to handle seasonal peaks, resulting in repeated outages during high-traffic events.

The Solution

We migrated the platform to AWS in risk-managed waves, rebuilding the checkout and inventory services on auto-scaling infrastructure with infrastructure as code and blue-green deployment.

The Outcome

The platform absorbed its highest-ever traffic during the following peak trading period with zero downtime, while overall infrastructure spend fell year-on-year.
