cloud concentration risk

Cloud concentration risk refers to the danger of relying on a single cloud provider for critical services, as a single outage can cause widespread disruption. A recent Azure Front Door outage on October 29 affected airlines like Alaska Airlines and Hawaiian Airlines, taking down websites and mobile apps and causing check-in failures. The fault was triggered by an inadvertent configuration change in Azure Front Door, Microsoft's global edge routing and application delivery fabric. Recovery involved rolling back to a last known good configuration, restoring most services within hours. This incident highlights the vulnerability of industries that depend heavily on one cloud provider, renewing scrutiny of cloud concentration risks across the aviation sector.
