Extended Principles

9. Availability (SLO Requirement)

Services should define, measure, and actively aim to meet high Service Level Objectives (SLOs) for uptime and latency, typically exceeding the baseline architectural needs.

10. Observability and Telemetry

Services must expose unified telemetry data (metrics, logs, and distributed traces) in a standardized format to enable real-time monitoring, debugging, and operational analysis.

11. Resource Isolation and Circuit Breaking

Services must implement internal mechanisms (like thread pools, bulkhead patterns, or circuit breakers) to isolate resource consumption and prevent cascading failures when dependent services are slow or unavailable.
