An important cog during PayPal’s releases is validation of End-to-End Customer Transaction Flows through automated test runs on the newly upgraded version before its released LIVE. The E2E customer flow tests are also simulated to run on each Availability Zones, to certify Changes, Maintenances on them before enabling to external customer traffic. Hence automated customer flow tests act as Change Reliability Lever. We have evolved this release vetting system to a Synthetic monitoring capability where PayPal Customer flow tests act as synthetics that are externalised to run at regular intervals to ensure they are functioning, available, and responding within specified Performance thresholds. Synthetic monitoring helps in Incident Prevention and reduce MTTD (Mean time to Detect) and thereby restore the site health within minutes. Its also facilitates proactive Alerting and Communicate the impact to the Customers proactively.
