When one tenant's excessive resource usage degrades performance for other tenants on the same infrastructure, this is called the:
The noisy neighbor alert fires when a tenant uses 150% of their quota — monitoring per-tenant resource consumption and alerting on anomalies is essential in shared infrastructure.

When the platform automatically limits the number of API requests a tenant can make per minute to prevent abuse, this is called:
The tenant throttling limits API calls per minute — throttling is typically implemented at the API gateway layer and returns HTTP 429 (Too Many Requests) when exceeded.

A dashboard that shows resource usage, error rates, and performance broken down by individual tenant is called:
The per-tenant metrics dashboard — this is essential for SaaS operations; it allows you to identify which tenant is experiencing issues or causing load.

When a tenant causing performance problems is moved to a different database shard to isolate their workload, this is described as:
The tenant is placed on a different shard to reduce impact — moving a noisy tenant to their own shard (or an underutilized one) protects other tenants from their load.

When communicating to affected tenants about an incident that only impacts a subset of users, this is called:
Multi-tenant incident communication vocabulary includes: 'This incident affects tenants on cluster X', 'If you're not seeing this issue, you are not affected', 'Affected tenants have been notified directly'.
