Deploy the ExtraHop Command Appliance in Google Cloud Platform

The following procedures explain how to deploy a virtual ExtraHop Command appliance in a Google Cloud environment. You must have experience deploying virtual machines in Google Cloud within your virtual network infrastructure.

To ensure that the deployment is successful, make sure you have access and ability to create the required resources. You might need to work with other experts in your organization to ensure that the necessary resources are available.

System requirements

Your environment must meet the following requirements to deploy a virtual Discover appliance in GCP:

  • You must have a Google Cloud Platform (GCP) account
  • You must have the ExtraHop deployment file, which is available on the ExtraHop Customer Portal.
  • You must have an ExtraHop product key.
  • You must have firewall rules configured to allow DNS, HTTP, HTTPS, and SSH traffic for ExtraHop administration. See https://cloud.google.com/vpc/docs/using-firewalls.
  • You must have access to a GCP instance type that most closely matches the guidelines described in the Command Appliance Performance Guidelines.

    The performance of the ExtraHop Command appliance depends on the number of sensors you are deploying in combination with the number of devices you expect the system to discover in your environment. To determine the appropriate sizing, see the Command Appliance Performance Guidelines.

Deployment Size Recommended Instance Type
Small n1-standard-4 (4 vCPU and 15 GB RAM
Medium n1-standard-8 (8 vCPU and 30 GB RAM)
Large n1-standard-16 (16 vCPU and 60 GB RAM)
Extra Large n1-standard-32 (32 vCPU and 120 GB RAM)
