team
Team at 'experienced backend team' maturity level
This scenario is rated 'experienced backend team' complexity. Engineers with 2+ years of production backend experience, including database tuning and monitoring.
Gap signal: Team frequently reaches for external help during incidents or struggles to debug multi-system issues independently.
process
Failure mode awareness and runbooks
The team must understand the 7 documented failure modes for this scenario: cache_stampede, thundering_herd, connection_exhaustion, tenant_noisy_neighbor. Each should have a documented detection procedure and runbook.
Gap signal: The team has no documented runbooks for the scenario's failure modes or cannot name them without reference material.
monitoring
Production-grade observability stack
The scenario requires real-time metrics, structured logging, and distributed tracing on all critical components. Alerting must be configured before going live.
Gap signal: No dashboards exist for the critical path metrics in the scenario.
infrastructure
Minimum team maturity: Experienced Backend Team
This scenario has high operational complexity. It is recommended for Experienced Backend Team teams or higher.
Gap signal: The requirement 'Minimum team maturity: Experienced Backend Team' is not yet in place.
infrastructure
Runbooks and alerting for high-severity risks
5 high-severity risks identified. Each requires a documented runbook, alerting threshold, and on-call response procedure before running in production.
Gap signal: The requirement 'Runbooks and alerting for high-severity risks' is not yet in place.
infrastructure
Event stream operations expertise
This architecture includes event stream infrastructure (Kafka, Kinesis, or similar). Operations requires consumer group management, partition assignment, dead-letter handling, and lag monitoring.
Gap signal: The requirement 'Event stream operations expertise' is not yet in place.
infrastructure
Mitigation for 2 high-risk topology node(s)
Nodes with high or critical risk exposure: Read-Heavy API Backend, Redis. Each requires documented mitigation before production deployment.
Gap signal: No mitigation strategy is documented for the high-risk nodes in the topology.
Infrastructure Requirements
Apache Kafka
high burdenDistributed event streaming platform designed for high-throughput, fault-tolerant, ordered, and durable log-based messaging between producers and cons
Managed: Amazon MSK (Managed Streaming for Kafka), Confluent Cloud, Azure Event Hubs (Kafka-compatible), Redpanda Cloud
PostgreSQL
medium burdenACID-compliant relational database with strong consistency, JSONB support, full-text search, and mature replication.
Managed: Amazon RDS for PostgreSQL, Amazon Aurora PostgreSQL, Google Cloud SQL for PostgreSQL, Azure Database for PostgreSQL, Supabase, Neon
Redis
low burdenIn-memory key-value store with optional persistence, supporting strings, hashes, lists, sets, sorted sets, and pub/sub.
Managed: Amazon ElastiCache for Redis, Google Cloud Memorystore, Azure Cache for Redis, Redis Cloud, Upstash
Observability Requirements
Monitor generic risk probe signals
Seed 'Cache Stampede (Dog-Pile) Risk Probe' identifies 2 metrics relevant to cache_stampede.
Seed 'Cache Stampede (Dog-Pile) Risk Probe' identifies 2 metrics relevant to cache_stampede.
Monitor connection pressure signals
Seed 'Connection Pool Pressure Under Load' identifies 4 metrics relevant to connection_exhaustion. Execution preview confirms this risk manifests under modelled load.

Redis command latency p99 > 0.5ms; gateway hot path p99 exceeding 2ms with Redis as the bottleneck (not upstream service
This signal indicates the architecture is approaching 'Tier 1: Redis Rate Limit Throughput'. Likely bottleneck: Single Redis instance processing all rate limit Lua scripts serially for all tenants across all gateway replicas.
Tier 1: Redis Rate Limit Throughput
Tenant reports that rate limit increase takes > 30 seconds to take effect across all gateway replicas; configuration cha
This signal indicates the architecture is approaching 'Tier 2: Configuration Propagation Latency'. Likely bottleneck: Local in-process cache TTL too long, or cache invalidation signal (Redis pub/sub or Kafka) not reaching all replicas.
Tier 2: Configuration Propagation Latency
Kafka producer batch queue filling faster than it can be flushed; usage event lag on the billing consumer > 5 minutes; K
This signal indicates the architecture is approaching 'Tier 3: Kafka Usage Event Throughput'. Likely bottleneck: Usage event Kafka produce throughput insufficient for peak request rate, or consumer lag accumulating faster than it can drain.
