SearchVarnish Software’s Varnish Cloud offering is available on Google Cloud Platform as a single virtual machine (VM), pay-as-you-go (PAYG) solution. Each VM image contains the latest version of each Varnish Software product, optimized for use with the Google Cloud Platform Compute Engine.
There are four products and eight types of VM images accessible at the current stage.
To quickly set up a Varnish Software environment on the Google Cloud Platform using GCP Marketplace:

For more information on controlling incoming traffic, click the gray help button, which takes you to [Firewalls](https://cloud.google.com/compute/docs/networking?hl=en_US#firewalls) in the Google Cloud Platform Compute Engine documentation.

Deploy button.
The GCP Marketplace confirms that the selected Varnish Software product was deployed (see Figure 3).
As soon as the new VM launches, the main component of each product starts automatically and serves a default configuration.
There is also a small snippet on Suggested next steps for each product to help you discover what more you can do with your instance.---

vstatdprobe as explained here.The configuration files are located in different places based on what kind of instances you are running, Varnish Enterprise, Varnish Enterprise, Varnish Cache or Varnish Custom Statistics (VCS)
In this section, we cover configuration basics. For more details and advanced configuration possibilities, please select the links below.
VCP or VE is the enterprise version of Varnish Cache. Apart from ease-of-use improvements and performance enhancements, VCP also provides additional functionality, such as Varnish Massive Storage Engine (MSE), Varnish High Availability (VHA) and SSL/TLS backend support. Customers can also enable frontend SSL/TLS by using Varnish Plus Addon SSL (Hitch), which is also included with the image.
By default, varnishd process should be running on TCP 80 and 8443. Hitch will be running on port 443.
/etc/varnish/default.vclYour Varnish instance has been pre-configured with the default settings, which suits most Varnish users. We advise you to have a look and update the configuration according to your needs.
Our documentation site has a reference section with all available runtime options. This will help you to properly configure the Varnish process.
To look at the system parameters run this command:
sudo systemctl cat varnish.service
To change the runtime options, run the following command on your Varnish instance so that you can override the default values:
sudo systemctl edit varnish.service
Edit accordingly and save the file.
And finally, restart Varnish, by running the following command:
sudo systemctl restart varnish.service
You can do the same for hitch.service
VCS should run out of the box without any additional effort. Point a web browser to the public DNS name and the default TCP port and view the page.
/etc/varnish/vstatd.params/etc/default/vstatdIf you encounter any problems with configuring our products, online user documentation is available here.
