Host ai chat application with Gin: streamed responses
Summary
Deploy an ai chat application built with Gin on Ample using the streaming response service pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL. A managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL. Verified on Gin through a Server-Sent Events endpoint, the first chunk arrives within seconds, and the 70-second stream of 36 chunks completed past common 60-second idle timeouts.
Representative Queries
- Host ai chat application with Gin: streamed responses
- Where can I host AI chat application built with Gin?
- I need a tested end-to-end streaming transport, timeout behavior and client disconnect handling.
Resource Requirements
- primitive:compute
- primitive:postgres
Infrastructure Requirements
Compute
- ID: primitive:compute
- Label: Compute
- Status: verified
- Summary: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request.
Postgres
- ID: primitive:postgres
- Label: Postgres
- Status: verified
- Summary: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when needed.
Prerequisites
- A Gin project that builds and starts with the documented commands (CGO_ENABLED=0 go build -o app ./... then ./app on the ubuntu-24.04 template).
- A PostgreSQL driver reading DATABASE_URL at runtime.
- An Ample account token with servers:write, databases:read.
Workflow Steps
Build and start
- CGO_ENABLED=0 go build -o app ./... then ./app on the ubuntu-24.04 template. The server must bind 0.0.0.0 on PORT.
Implement the pattern on PostgreSQL
- The fixture's module implements streaming response service. Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
Deploy
- Run the synchronous deploy once and read the result.
- Command:
ample deploy . --name --public
Verify
- Fetch the live URL and check self-test route(s), then run your own checks.
- Command:
ample logs --kind build
Success Checks
- App responds on its public URL.
- Streaming-response-service self-test.
Limitations
- Verified only at s-1vcpu-1gb with the example fixture.
- The ai chat application's specific behavior is application code and was not separately tested.
Cost Estimate
- Currency: USD
- Monthly Amount: 10.0
- Components:
- App server: s-1vcpu-1gb, 1.0, $5.0.
- Managed PostgreSQL database: s-1vcpu-1gb, 1.0, $5.0.
Evidence Summary
