Staging environment reference

The table below compares staging with a second environment that an operator adds.

Item	Staging	Second environment
Deploy command	VSA_ADP_KB_ID=<kb-id> make deploy-staging	Operator-defined (mirror deploy-staging)
Region	us-west-2	Any region where Amazon Nova 2 Sonic is available
CDK stack prefix	vsa-staging-*	vsa-<stage>-*
AgentCore voice runtime	vsa_supervisor_bidi_staging	vsa_supervisor_bidi_<stage>
AgentCore text runtime	vsa_supervisor_text_staging	vsa_supervisor_text_<stage> (configure separately)
Nova 2 Sonic region	us-west-2 (native; matches execution-role region)	Must match the execution-role region
Auto-deploy	Yes — GitHub Actions on push to main after Tier 1/2/3 evals pass	Operator-defined
Demo seed	Runs automatically as part of make deploy-staging	make seed STAGE=<stage> after fresh deploy

Note

Amazon Nova 2 Sonic voice is available in select regions. The staging environment uses us-west-2 natively; the execution-role region and the Nova 2 Sonic invocation region must match. Cross-region invocations are rejected by the bidirectional stream allowlist. Consult the Amazon Bedrock service documentation for the current Nova 2 Sonic regional availability table before choosing a second-environment region.
