Architecture and key concepts

EVA’s 5 layers

EVA turns raw infrastructure data into actionable operational intelligence through five functional layers working in sequence.

• Layer 1 — Ingestion & processing: edge collectors, Kafka pipeline and canonical normalization.
• Layer 2 — Correlation & topology: Union-Find engine and topology inference.
• Layer 3 — Machine Learning: anomaly detection and root cause prediction.
• Layer 4 — Generative AI: incident narrator and natural-language query.
• Layer 5 — Presentation & automation: NOC, reports and EOE orchestration.

Multi-tenant by design

Every record carries a tenant_id extracted from the JWT and applied as a mandatory filter on every query, ensuring full isolation between customers.
