Cedar is an open-source authorization policy language, developed by AWS, for expressing fine-grained access-control rules in applications and agents.
No evidence-backed relationships are recorded.
Keeping the Iceberg table format governance-unaware was a deliberate call. That leaves the catalog as the only thing standing on the path of every read. A dev.to guide lists six pieces an operator has to source above it.
Reality
A dev.to design post puts a per-task scope check under every tool invocation and caps the agent's cloud credentials at fifteen minutes. The restrictions work by taking capability away from the model.
Reality
The company says 88 percent of its AI proofs-of-concept never reach widescale deployment, and it blames the identity, session and evaluation layers each team was rebuilding, so APEX builds them once on Amazon Bedrock AgentCore.
Reality
A dev.to writeup deployed AWS's own migration sample, reran the repo's diff-checking script, and reports that the managed runtime, gateway and memory are worth taking while the LangGraph loop stays as written.
Reality
A published EKS control-plane design puts typed proposals, deterministic evidence, Cedar policy evaluation and bounded runbooks between a model's suggestion and production.
Reality
Agent Governance Toolkit puts policy checks in the execution path rather than the prompt. The seam: the kernel is middleware inside the agent's process, so containers still do the isolating.
