[MULTI-CLOUD FEDERATION]

ENGINEERING HUB

Platform & Engineering Architecture

Designed for SRE, FinOps, and DevOps teams. Zero agent installation, 100% read-only cloud IAM connectors, and native IaC stack integrations across AWS, Azure, GCP, and Kubernetes.

//SYSTEM TOPOLOGY SPECIFICATION // SPEC-REF: AO-ARCH-2026

AP-SOUTH-1 REGIONAL ANCHORSTRICT READ-ONLY

ARCHITECTURE MODULE · PLANE 01STRICT READ-ONLY · EPHEMERAL STS

Customer Cloud Ingestion Plane

Communicates directly with native cloud control APIs using short-lived, time-bound Security Token Service (STS) assume-role nonces. No resident daemon, zero node overhead, and 0 stored cloud credentials.

ARCHITECTURAL INVARIANTS

Zero agent binaries or daemonsets on customer compute instances
Session TTL bounded between 900s and 3,600s with dynamic rotation
Immediate role revocation SLA (<1 second) via single IAM policy detach

FEDERATED PROTOCOLS

AWS STS AssumeRole with ExternalId Nonce
Azure Managed Identity & App Registrations
GCP Workload Identity Federation
Kubernetes Read-Only ClusterRole & ServiceAccount

DAEMON FOOTPRINT0 MB (Agentless)

STORED STATIC KEYS0 (Zero Keys)

SECURITY & INFRASTRUCTURE DIMENSION	ARTHAOPS TWO-PLANE ARCHITECTURE	TRADITIONAL APM AGENTS	LEGACY CLOUD COST SAAS
Host & Compute Footprint	0 MB (Agentless, 100% native cloud API polling)	Resident DaemonSet / agent binary on every node	Optional heavy daemon with 100-300MB RAM footprint
