Salesforce’s Cloud Atlas team operates a globally distributed identity data store that must maintain five nines of availability, roughly five minutes of downtime per year. The team redesigned service protection after per-instance rate limiting proved insufficient under autoscaling and increasingly bursty, unpredictable agent-driven traffic. The new approach combines intelligent load shedding, which monitors queue time as an early indicator of system pressure before error rates spike, with coordinator-free global quota management. Servers independently measure and share customer usage to throttle noisy tenants without a centralized coordinator, preventing one customer’s surge from affecting others. This design prevents cascading failures by shedding lower-priority work before overload spreads across dependent services, ensuring graceful degradation rather than widespread outage.
