+# Web Server Using Azure Virtual Machine
+
+This example provisions a Linux web server in an Azure Virtual Machine and gives it a public IP address.
+
+## Deploying the App
+
+To deploy your infrastructure, follow the below steps.
+
+### Prerequisites
+
+1. [Install Pulumi](https://www.pulumi.com/docs/get-started/install/)
+2. [Configure Azure Credentials](https://www.pulumi.com/docs/intro/cloud-providers/azure/setup/)
+
+## Running the App
+
+1. Create a new stack:
+
+   ```
+   $ pulumi stack init dev
+   ```
+
+2. Configure the app deployment. The username and password here will be used to configure the Virtual Machine. The
+   password must adhere to the [Azure restrictions on VM passwords](
+   https://docs.microsoft.com/en-us/azure/virtual-machines/windows/faq#what-are-the-password-requirements-when-creating-a-vm).
+
+   The supplied password must be between 6-72 characters long and must satisfy at least 3 of password complexity
+   requirements from the following:
+    - Contains an uppercase character
+    - Contains a lowercase character
+    - Contains a numeric digit
+    - Contains a special character
+    - Control characters are not allowed
+
+   ```
+   $ pulumi config set azure-native:location westus    # any valid Azure region will do
+   $ pulumi config set username webmaster
+   $ pulumi config set password --secret <your-password>
+   ```
+
+   Note that `--secret` ensures your password is encrypted safely.
+
+3. Stand up the cluster by invoking pulumi
+    ```bash
+    $ pulumi up
+    ```
+
+4. Get the IP address of the newly-created instance from the stack's outputs:
+
+   Go to azure portal to service `Virtual Machines`.
+   Find newly created virtual machine and get `Public IP address` from it.
+
+5. Check to see that your server is now running:
+
+    ```
+    $ curl http://<Public IP address from virtual machine>
+    Hello, World!
+    ```
+6. From there, feel free to experiment. Simply making edits and running `pulumi up` will incrementally update your
+   stack.
+
+7. Once you've finished experimenting, tear down your stack's resources by destroying and removing it:
+
+    ```bash
+    $ pulumi destroy --yes
+    $ pulumi stack rm --yes
+    ```
