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.)

PREREQUISITES

Before you start

• Authorized access to the AWS EC2 app source and its export tooling
• An inventory of every component in scope and out of scope
• A validated backup or copy before any cutover
• An Ample account token with servers:write, databases:read

TESTED CONFIGURATION

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

STEP BY STEP

How to do it

1. 1

Inventory the source

List what AWS EC2 app provides beyond the component you are moving. Out of scope here: Cron jobs, local files on the instance disk, security-group networking and IAM instance roles are not migrated; use managed databases, buckets and encrypted env instead.

2. 2

Source step 1

Collect the process environment from the instance (systemd unit or process manager config) into an env file kept out of the repository

3. 3

Source step 2

Replace the instance's process manager with the repository's start command; Ample supervises the process and restarts it

4. 4

Source step 3

Inventory what else runs on the instance: databases, cron, reverse proxy rules, local files

5. 5

Deploy on Ample in parallel

next build then next start -H 0.0.0.0 -p $PORT on the node-22 template. Pass the exported variables with --env; keep the source running.

ample deploy . --name <app-name> --public --env-file .env.production

6. 6

Validate before cutover

Run the app's own checks and, for data, compare counts and checksums; the example checks are the pattern self-tests (/p/configuration-secrets, /p/relational-records).

7. 7

Cut over

Add the custom domain with ample domain add, update DNS from the instance or load balancer, keep the instance until verified, then stop it.

8. 8

Rollback

Point DNS or configuration back to the source. The source was never modified; deletion is a separate, user-executed step after validation.

EXAMPLES

Tested examples

• Next.js pattern fixture (destination) (tests/deploy-canaries/next-js-patterns): Verified destination basis: Next.js compute.

SUCCESS CHECKS

How to know it worked

• destination app responds on its public URL (/ on the live URL, expect ample canary next js patterns)
• configuration-secrets check from the destination example (/p/configuration-secrets on the live URL, expect see the pattern fixture checks)
• relational-records check from the destination example (/p/relational-records on the live URL, expect see the pattern fixture checks)
• data or object counts and checksums match the source

LIMITATIONS

Know the limits

• Documentation only: nothing is executed automatically and no execution binding is offered.
• The source-side procedure is documented from AWS EC2 app's standard tooling and was not executed in this catalog's evidence; the destination side was verified with the pattern fixture.
• No full source-product parity is claimed: Cron jobs, local files on the instance disk, security-group networking and IAM instance roles are not migrated; use managed databases, buckets and encrypted env instead.
• Verified on the node-22 template at s-1vcpu-1gb; region, compliance and request-duration limits are unknown.
• Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures on the managed side are not verified beyond the pattern checks.

COST

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

Destination always-on monthly price of the tested sizes; apps auto-pause when idle. Source costs are unknown to Ample.

EVIDENCE

Verification evidence

• canary_run on 2026-09-21T02:34:39Z at revision 1d28ae0-dirty (CLI 0.1.21): Destination side verified: the Next.js pattern fixture deployed on Ample (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template) and its checks passed (the app built, started and answered on its public HTTPS URL with encrypted configuration delivered). The source-side export from AWS EC2 app is documented from the vendor's standard tooling and was not executed by this catalog's evidence. (expires 2027-03-20T02:34:39Z)

EXECUTION

Execution binding

No execution binding. This recipe is documentation only; nothing is executed automatically.
