With all of the new visual studio plug-ins now available, how feasible is it to host OLLama on IIS as a public resource for our company?

Yes, you can run OLLama on a Windows Server and make it accessible as a public resource for clients. While OLLama is designed to run locally and serve models through an API, setting it up on IIS (Internet Information Services) is possible with some configuration. Steps to Set Up OLLama on a Windows Server: Install OLLama on Windows Server Download and install OLLama for Windows from OLLama’s website. Open a terminal (PowerShell or Command Prompt) and verify it works by running:ollama run mistral (Replace "mistral" with the model you plan to use) Run OLLama’s API Server OLLama provides an API by default. You can start the server manually:ollama serve By default, it listens on localhost:11434. Enable External Access By default, OLLama binds only to localhost. To allow external access:ollama serve --host 0.0.0.0 You might need to configure Windows Firewall to allow traffic on port 11434. Set Up a Reverse Proxy on IIS Install IIS (if not already installed) Enable URL Rewrite and Application Request Routing (ARR) Open IIS Manager → Select your server Install URL Rewrite and ARR from the Microsoft IIS extensions site. Create a New Site or Bind to an Existing One Set up a new site in IIS or use an existing one. Point it to a folder with a minimal web app (if needed). Configure a Reverse Proxy to OLLama In IIS Manager, select the site and open URL Rewrite. Create a new rule: Match URL: * Conditions: None Action: Action Type: Rewrite Rewrite URL: http://localhost:11434/{R:1} Preserve Host Headers: Yes Apply the rule. Secure the Public API Since OLLama does not have built-in authentication, you should: Enable HTTPS on IIS Restrict API Access (e.g., IP whitelisting, API key middleware) Use a Firewall or WAF to prevent abuse Test the Setup Access OLLama’s API externally via your domain or public IP:curl -X POST "https://yourdomain.com/api/generate" -H "Content-Type: application/json" -d '{ "model": "mistral", "prompt": "Hello, world!" }' Alternative Approach (Without IIS) Instead of IIS, you can also use Nginx or a lightweight FastAPI/Flask wrapper if IIS adds unnecessary complexity. Would you like help with setting up any specific step?

Step 1: Install OLLama on Windows Server Download and Install OLLama for Windows Visit OLLama's website and download the Windows installer. Run the installer and follow the prompts. Verify the Installation Open PowerShell or Command Prompt and run: ollama run mistral If the model loads and responds, the installation is successful. If you need another model, you can install it by running: ollama pull llama3 Step 2: Start OLLama's API Server OLLama includes a built-in API that listens on localhost:11434. Start the API Server: ollama serve This runs OLLama in API mode on localhost:11434. Allow External Access (Required for IIS or public access): By default, OLLama only listens on localhost, meaning no external devices can connect. To change this, run: ollama serve --host 0.0.0.0 This allows OLLama to be accessed from other devices. Step 3: Configure Windows Firewall to Allow Traffic Since we opened OLLama’s API to external access, we need to allow inbound traffic on port 11434. Open Windows Defender Firewall Press Win + R, type wf.msc, and hit Enter. Click on Inbound Rules → New Rule. Create a New Rule Rule Type: Port Protocol: TCP Port: 11434 Action: Allow the connection Profile: Select all profiles (Domain, Private, Public) Name: OLLama API Click Finish. Step 4: Install and Configure IIS (Internet Information Services) We will set up IIS as a reverse proxy to OLLama so clients can access it via an easy-to-use domain or IP. 1. Install IIS on Windows Server Open PowerShell (Admin) and run: Install-WindowsFeature -name Web-Server -IncludeManagementTools After installation, restart the server. 2. Enable Required IIS Features IIS needs Application Request Routing (ARR) and URL Rewrite to act as a proxy. Open IIS Manager (inetmgr). Select the server (left panel). Click Manage Server → Get New Web Platform Components. Install: Application Request Routing (ARR) URL Rewrite Step 5: Set Up a Reverse Proxy on IIS Now, we configure IIS to forward incoming requests to OLLama. 1. Create a New Site in IIS Open IIS Manager. Right-click Sites → Add Website. Site name: OLLamaAPI Physical path: C:\inetpub\wwwroot Binding: http \| Port: 80 (or 443 for HTTPS) Click OK. 2. Configure Reverse Proxy in IIS Select the new site (OLLamaAPI). Open URL Rewrite. Click Add Rules... Choose Reverse Proxy (if available) or create a custom rewrite rule: Requested URL: * Conditions: None Action Type: Rewrite Rewrite URL: http://localhost:11434/{R:1} Preserve Host Headers: Yes Apply and restart IIS. Step 6: Secure the API (Optional but Recommended) Since this will be a public API, we should add security measures. Enable HTTPS (SSL) Use Let’s Encrypt or a commercial SSL certificate. Add HTTPS binding in IIS Manager → Sites → OLLamaAPI. Restrict Access by IP Use IIS IP Restrictions to allow only certain clients. Add Authentication You can add Basic Authentication in IIS or implement API key authentication. Step 7: Test External Access From another machine, try: curl -X POST "http://yourserver.com/api/generate" -H "Content-Type: application/json" -d '{ "model": "mistral", "prompt": "Hello, world!" }' If it responds, your setup is complete!
