Professional training: asset library using Next.js
Summary
A asset library blueprint for professional training built with Next.js on Ample. Domain schema: course_groups (certification, cohort, start_at, end_at): certification cohorts; memberships (course_group_id, participant_email, employer, role): participants and trainers; sessions (course_group_id, starts_at, module, location_or_link): training sessions; materials (course_group_id, module, object_key, visibility): course materials and exam guides; uploads (id, owner_reference, object_key, content_type, size, uploaded_at): validated uploads linked to their owner. Public information: certification catalog, cohort dates, trainer credentials. Kept out of scope until handling is reviewed: exam results, employer billing, participant identity. Exam results and certifications are personal records; only cohort logistics and materials are modeled. Technical basis verified on Next.js: 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).
Infrastructure requirements
- 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.)
Prerequisites
- 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 createpassed as encrypted S3_* environment variables - A review of which professional training data classes may be handled at all; this blueprint models public information only
Exact tested configuration
- template:
node-22 - runtime:

s-1vcpu-1gb - install:

npm run build --if-present - start:
npm run start
Steps
- Model the professional training domain. Create the tables course_groups, memberships, sessions, materials, uploads. Certification cohorts lives in course_groups; keep the sensitive classes (exam results, employer billing, participant identity) out of this schema.
- Workflow step 1. Model assets linked to their owning group or workspace
- Workflow step 2. Validate uploads and store them in the private bucket; link each object to its row
- Workflow step 3. Authorize downloads by membership
- Workflow step 4. Deploy and verify rejection of disallowed files and a linked upload
- 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=... - Verify. Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the professional training 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.
Success checks
- 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-uploadson the live URL, expect see the pattern fixture checks)
Limitations
- The technical basis (browser file uploads on Next.js) was verified with the pattern fixture; the professional training 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. Exam results and certifications are personal records; only cohort logistics and materials are modeled.
- 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 verified.
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.

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 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 Professional training schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-20T02:34:39Z)
