Host Admin Dashboard with ASP.NET Core: Application Activity History

Summary

Deploy an admin dashboard built with ASP.NET Core on Ample using the transactional workflows pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, with a managed PostgreSQL 16 database auto-provisioned and injected as DATABASE_URL. Verified on ASP.NET Core: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Not separately tested: your domain records, validation rules, and concurrency policy; treat the admin dashboard-specific behavior as your application code.

Workload Requirements

• Framework: ASP.NET Core
• Workload: Admin dashboard
• Release Status: Published
• Support Status: Verified
• Execution Status: Ready

Resource Requirements

• Compute: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
• Postgres: 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

• An ASP.NET Core project that builds and starts with the documented commands (dotnet publish -c Release -o out in the builder, then dotnet .dll on the dotnet-10 template with ASPNETCORE_URLS bound to PORT)
• A PostgreSQL driver reading DATABASE_URL at runtime (auto-provisioned when omitted, or supplied with --env)
• An Ample account token with servers:write, databases:read

Workflow Steps

1. Build and start: dotnet publish -c Release -o out in the builder, then dotnet .dll on the dotnet-10 template with ASPNETCORE_URLS bound to PORT.
2. Implement the pattern on PostgreSQL: Copy the transactional workflows approach into your schema; keep migrations idempotent and run them with --release-command.
3. Deploy: Run the synchronous deploy once and read the result.
4. Verify: Fetch the live URL and run your own checks.

Success Checks

• App responds on its public URL
• Transactional-workflows self-test

Limitations

• Verified on the dotnet-10 template at s-1vcpu-1gb; other sizes, templates, and ASP.NET Core major versions are not verified.
• The admin dashboard itself behavior is application code and was not separately tested.

Cost Estimate

• Currency: USD
• Monthly Amount: $10.00
• Components:
  • App server: s-1vcpu-1gb, Quantity: 1.0, Monthly Amount: $5.0
  • Managed PostgreSQL database: s-1vcpu-1gb, Quantity: 1.0, Monthly Amount: $5.0
• Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.

Evidence Summary

• ASP.NET Core pattern fixture deployed on Ample; checks passed for transactional-workflows and configuration-secrets.
• Summary of checks includes optimistic version check and event row transactions.
