Support envelope
Validated regions, status and the known limitations each project documents, collected in one place for four samples centered on Amazon Bedrock and Amazon Bedrock AgentCore.
The support envelope applies to the exact tested implementation: the reference implementations, regions and configurations each project names. Replacements and other regions require independent validation (root README (opens in new tab)). The limitation bullets below are quoted from the project files without paraphrase.
1. LearnBuilding an Enterprise Agentic AI Platform
| Fact | Value | Source |
|---|---|---|
| Validated regions | AWS-run events: us-west-2. Self-paced: us-west-2 (default), us-east-1, or eu-west-1. Other regions are not supported. The contentspec.yaml deployableRegions list is us-west-2, us-east-1 and eu-west-1. Workshop Studio events provision the account in us-west-2 (content/introduction/getting-started/aws-event.en.md). | contentspec.yaml (opens in new tab) |

| Status | Published on AWS Builder Center (Workshop Studio); last published 2026-08-18 Publication state and date come from the Workshop Studio catalog entry, not from the repository, which holds no publish record to quote. | Workshop Studio catalog (opens in new tab) |
| Version | not documented The workshop has no version badge, tag or CHANGELOG. contentspec.yaml declares only the Workshop Studio schema version 2.0. | none |
Known limitations, as documented
- Region lock
Other regions are not supported

- AWS Agent Registry availability
the AWS Agent Registry control plane is not yet generally available everywhere, which breaks Modules 3b and 4.

- Model access
Serverless Bedrock models enable on first invocation; Anthropic models need a one-time use-case submission per account.

- Where commands run
Run everything in the IDE terminal/notebooks, not your local machine.

2. BuildAgentCore Visual Workflow Platform
| Fact | Value | Source |
|---|---|---|
| Validated regions | One of seven selected release Regions: us-east-1, us-east-2, us-west-2, eu-central-1, eu-west-1, eu-west-2 or eu-west-3; us-east-1 is the default Every other value of AWS_REGION is refused by deploy.sh, by the CDK app at synth, and by the deploy API. Outside us-east-1 the WAF web ACL is REGIONAL on the Cognito user pool and the CloudFront distribution runs without an edge ACL. eu-central-1 and eu-west-2 run without managed Web Search; eu-west-3 also has no AWS Agent Registry. | README.md: Prerequisites (opens in new tab) |
| Default region | us-east-1 | README.md: Quickstart (opens in new tab) |
| Status | Version 0.1.0 released 2026-07-17, with unreleased changes recorded in CHANGELOG.md | CHANGELOG.md (opens in new tab) |
| Version | 0.1.0 plus unreleased changes | CHANGELOG.md (opens in new tab) |
Known limitations, as documented
- WAF outside us-east-1
The same rule set as a

- Seven-Region release envelope
Production deploys to exactly one of seven selected Regions:
us-east-1,us-east-2,us-west-2,eu-central-1,eu-west-1,eu-west-2oreu-west-3.deploy.sh, the CDK app and the deploy API refuse every other Region, includingus-west-1and every APAC Region.eu-central-1andeu-west-2run without managed Web Search;eu-west-3also has no AWS Agent Registry. Expanding the set requires the Region matrix, feature gates, tests and live certification to change together.Source: README.md: Deploying to another region (opens in new tab)
- RBAC enforcement can be switched off
Scope-based RBAC (
services/rbac.py) ships enforcing by default (RBAC_ENFORCE=true).RBAC_ENFORCE=false ./scripts/deploy.shallows every request and logsRBAC advisory (would-deny): ...instead; it exists to size the blast radius of an upgrade, not as a long-term posture.Source: RBAC_ROLLOUT.md: The advisory escape hatch (opens in new tab)
- Control plane has no VPC egress
The proxy must be reachable from the deploy Lambda. The control plane has no VPC egress, so a VPC-private LiteLLM cannot be probed and the deploy will fail at step 3 even though a VPC-mode Runtime could reach it at invoke time.

3. GovernEnterprise MCP Governance Gateway
| Fact | Value | Source |
|---|---|---|
| Validated regions | us-west-2 by default; configurable; no tested-regions list is published | README.md (opens in new tab) |
| Default region | us-west-2 | README.md: Deploy (opens in new tab) |
| Status | Sample and demonstration stack; not hardened for production | README.md: Security notes (opens in new tab) |
| Version | not documented No version badge, tag or CHANGELOG in the project folder. | none |
Known limitations, as documented
- Not hardened for production
This is a sample / demonstration stack. It is deployed to a real account and is safe to demo, but it is not hardened for production
- Access token versus ID token
Query F is a known demo limitation, not a bug.
custom:roletherefore never reaches the policy engine, so the role-gatedpermitnever fires.Source: README.md (opens in new tab)
- Tighten the gateway-resource IAM scope for multi-gateway accounts.
This sample deploys a single gateway, so the wildcard effectively resolves to it. If your account runs multiple gateways in the region, restrict the statement to the specific gateway ARN after the first deploy, or use a two-phase deploy (create the gateway, then update the policy with its exact ARN).

4. ScaleEnterprise Agentic AI Platform Blueprint
| Fact | Value | Source |
|---|---|---|
| Validated regions | Validated in eu-west-1; SCP allow-list us-west-2, us-east-1, eu-west-1 The SCP region allow-list comes from PLATFORM_APPROVED_REGIONS in packages/platform-baselines/src/approved-regions.ts. A different Region is a new validation target, not a configuration-only substitution. | README.md: 5. Prerequisites (opens in new tab) |

- Runtime network posture
Network posture:
networkMode = PUBLIC, matching the live commit.Source: d03-workstream-runtime-memory-stack.ts (opens in new tab)
- Evaluation gate
This is a scaffolded implementation
- Region support
A Region is supportable only after independent service-availability, model and residency, IAM/SCP, availability-zone, strict synth, positive/adversarial, rollback, observability, and teardown gates pass there. Do not extrapolate from Ireland.
