Fault‑Tolerant Architecture for High‑Traffic ECommerce Platforms

Author(s) Priyadarshini Jayakumar
Country United States
Abstract This white paper explains the benefits of building fault‑tolerance for platforms that must withstand extreme and unpredictable surges in demand like eCommerce systems. The architecture that powers this fault-tolerance integrates the following proven elements:
(1) Active‑ Active deployments that operate multiple live environments at the same time;
(2) Segmented routing that distributes user traffic across environments by geography, time, and behavior cohorts;
(3) Automated environment provisioning that treats an entire stack, namely infrastructure, application code, and configuration as software using Infrastructure as Code (IaC) and Continuous Integration and Continuous Delivery (CI/CD) pipelines; and
(4) Operations enhanced by artificial‑intelligence(AI) agents for anomaly detection, triage, and self‑healing.
The result is a system that can prevent failures from becoming outages, recover quickly when degradations occur, and sustain customer experience during peak traffic events such as holiday campaigns and flash sales.
