INFRASTRUCTURE

What it needs

• Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.)
• Postgres: verified (Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.)
• S3-compatible object storage: verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)

Before you start

• A Next.js project (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template)
• A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
• Bucket credentials from ample bucket create passed as encrypted S3_* environment variables
• A review of which digital agencies data classes may be handled at all; this blueprint models public information only

Exactly what was tested

• build: npm run build --if-present
• install: npm install
• runtime: node
• size: s-1vcpu-1gb
• start: npm run start
• template: node-22

How to do it

1. 1

Model the digital agencies domain

Create the tables client_entities, engagements, approval_rounds, deliverables, document_access. Client brands lives in client_entities; keep the sensitive classes (unreleased creative and campaign plans, client analytics exports, brand credentials) out of this schema.

2. 2

Workflow step 1

Model client entities and engagement periods; every document belongs to one engagement

3. 3

Workflow step 2

Authorize by client entity and role before any storage access (401 without identity, 403 for the wrong client)

4. 4

Workflow step 3

Store documents in the private bucket and stream them through the app

5. 5

Workflow step 4

Deploy and verify the negative authorization tests and an authorized download

ample deploy . --name <app-name> --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...

6. 6

Deploy

Run the synchronous deploy once and read the result. Re-running with no change is a no-op.

7. 7

Verify

Run the pattern self-test(s) from the example (/p/private-document-library) and your own acceptance checks for the digital agencies workflow.

ample logs <deployment_id> --kind build

Tested examples

• Next.js pattern fixture (tests/deploy-canaries/next-js-patterns): Verified private document library basis for this blueprint.

How to know it worked

• app responds on its public URL (/ on the live URL, expect ample canary next js patterns)
• private-document-library self-test from the example (/p/private-document-library on the live URL, expect see the pattern fixture checks)

Know the limits

• The technical basis (private document library on Next.js) was verified with the pattern fixture; the digital agencies schema and workflow are an original design for this blueprint and were not executed as a separate application.
• No health, financial, privacy or other compliance claim is made. Unreleased creative is confidential; brand platform credentials never belong in these flows.
• Public content and synthetic examples only until actual data-handling requirements have been reviewed.
• Verified on the node-22 template at s-1vcpu-1gb; region, request-duration limits and other sizes are unknown or unverified.
• Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.
• PutObject and GetObject with path-style addressing are verified; other S3 operations and CDN cache rules are not.

Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371).

• app server x1 s-1vcpu-1gb: 5.00 USD
• managed PostgreSQL database x1 s-1vcpu-1gb: 5.00 USD

Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.

Verification evidence

• canary_run on 2026-09-21T02:34:39Z at revision 1d28ae0-dirty (CLI 0.1.21): Next.js pattern fixture deployed on Ample (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template); the private document library checks passed: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). The blueprint's Digital agencies schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-20T02:34:39Z)
