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 law firms data classes may be handled at all; this blueprint models public information only

How to do it

1. Model the law firms domain
   Create the tables client_entities, matters, document_requests, shared_documents, uploads. Clients with conflict-check status lives in client_entities; keep the sensitive classes (privileged communications and case files, identity and financial documents, opposing-party information) out of this schema.

2. Workflow step 1
   Model document requests per engagement with due dates and status

3. Workflow step 2
   Validate uploaded files (type, size) before storing them in the private bucket and linking them to the request

4. Workflow step 3
   Authorize uploads by client entity

5. Workflow step 4
   Deploy and verify rejection of disallowed files and a linked upload

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

   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=...
   

7. Verify
   Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the law firms workflow.

   ample logs <deployment_id> --kind build
   

Tested examples

• Next.js pattern fixture (tests/deploy-canaries/next-js-patterns): Verified browser file uploads 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)
• browser-file-uploads self-test from the example (/p/browser-file-uploads on the live URL, expect see the pattern fixture checks)

Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision 515b7316fc6e5a81679407ae0c811146ceb2c5c7).

• 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 (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 browser file uploads checks passed: content-type and size validation that rejects disallowed files, an object written to a private bucket and a row linking the record to the object key (reject=ok upload=ok linked=ok). The blueprint's Law firms schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-20T02:34:39Z)
