Developer Tools Platform

Summary

A multi-tenant developer tooling platform providing CI/CD pipeline execution, log aggregation, code analysis, and dependency scanning across isolated tenant organizations. Tenant isolation is the primary correctness constraint: a security boundary violation between tenants is a critical incident, not a performance event. PostgreSQL row-level security enforces data isolation; Redis manages job queues and distributed locks; Elasticsearch indexes pipeline log output for search; Kafka delivers webhook events to tenant-registered endpoints; MinIO stores pipeline artifacts. Resource quota enforcement prevents any single tenant's burst from affecting others.

Problem Statement

Developer tooling platforms have a particularly dangerous multi-tenant failure mode: a misconfiguration that exposes one tenant's source code, pipeline secrets, or artifact store to another tenant is a critical security breach, not just a data quality issue. Unlike SaaS billing or user management, the cross-tenant leakage of build artifacts or environment variables has direct exploitation potential. At the same time, the workload is bursty and heterogeneous: a single tenant triggering a monorepo CI build against 50 microservices generates more job queue volume in 60 seconds than a small tenant generates in a week. Shared infrastructure must enforce resource quotas hard enough to protect other tenants while remaining operationally simple enough for a small platform team to run. Webhook delivery adds an outbound reliability dimension: the platform must deliver pipeline completion events to tenant-registered HTTP endpoints without accumulating unbounded retry queues when tenant endpoints are down.
