How our approach to radical transformation of customer-facing infrastructure caused no downtime and a successful Christmas trading season

Executive Summary

A major e-commerce group working with Threatplane combined competent project management, careful security engineering and staggered planned rollouts allowed key customer-facing infrastructure to be radically changed with no operational disruption, leading to a successful Christmas trading season.

Customer Profile

Company Overview

Industry: eCommerce Retail

Geography: UK-based with global operations

Company Type: Major Online Retailer

Project Scope

Properties: 279 Domains

Infrastructure: AWS

Downtime Tolerance: Zero

The Challenge

Our customer needed to migrate customer-facing infrastructure, hosting 279 unique DNS domains for multiple brands, TLDs and alternate names, from a legacy WAF to new WAF services in AWS. The criticality of the traffic to these domains and proximity to peak trading periods meant success was paramount.

Business-Critical Availability

As a pure online retailer, any website downtime directly impacts revenue. During peak seasons, even minutes of downtime could cost hundreds of thousands in lost sales.

Complex Domain Portfolio

279 distinct domain names across various brands and aliases, with two dozen domains carrying majority revenue concentration.

Solution Overview

Comprehensive Project Management

We worked closely with the customer to carefully plan every aspect of the migration.

  • Full project plan agreed with customer at outset
  • Each domain risk-assessed and prioritised accordingly
  • Layered contingency strategy provided strong assurance of success and prompted careful, lean planning
  • Testing and preparatory work front-loaded to anticipate and manage all delivery risks

Controlled Migration Sequence

Every step was carefully designed to fail fast and deliver safe outcomes for customers, even in the event of failures.

  • Migration & validation process automated to ensure complete consistency and speed of cutover
  • Sample of domains tested with baseline WAF rulesets and new rules crafted to resolve incompatibilities ahead of time
  • Blue/Green approach to enable fast fallback in the event of issues

Security Capability

The customer gained a modern, performant, flexible WAF capability running on new AWS infrastructure at minimal cost uplift. We also added new features to the deployment, including:

  • OpenSearch based SIEM platform to analyse and triage packets dropped from the WAF
  • Efficient tiered storage solution to minimise use of hot storage while permitting queries against older data
  • Processes to quickly disable or configure particular WAF rules in the event of disruption of legitimate traffic
