~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This section describes how to install and start H2O Flow (H2O-3 web offering) in a Google Compute environment using the available Cloud Launcher offering.

1. In your browser, log in to the Google Compute Engine Console at https://console.cloud.google.com/. 

2. In the left navigation panel, select **Cloud Launcher**.

4. Click **Launch on Compute Engine**.

 - Specify a name for this deployment.
 - Select a zone for the deployment.
 - Select or customize a machine type and memory amount.
 - Specify the number of nodes for the virtual machine.
 - Specify the boot disk type and size (in GB).
 - Specify the network and subnetwork names. 

 Click **Deploy** when you are done. H2O-3 will begin deploying. Note that this can take several minutes.

5. A summary page displays when the compute engine is successfully deployed. This page includes the instance ID and the username (always **h2oai**) and password that will be required when starting H2O-3. Click on the Instance link to retrieve the external IP address for starting H2O-3.

6. Start H2O-3 using one of the following methods:

  **Python**: Run the following

  ::

    h2o.connect(url="https://[external ip]:443", auth=(username, password))

  **R**: Run the following

  ::

    h2o.connect(ip="[external ip]", port=443, https=TRUE, username=username, password=password)

  **Flow**: In your browser, go to http://[External_IP]:443 or https://[External_IP]:80 to start Flow. Enter your username and password when prompted. 

   **Note**: When starting H2O Flow, you may receive a message indicating that the connection is not private. Note that the connection is secure and encrypted, but H2O uses a self-signed certificate to handle Nginx encryption, which prompts the warning. You can avoid this message by using your own self-signed certificate.
