Provision a Google Axion C4A Arm VM

In this section you’ll create a Google Axion C4A Arm-based virtual machine on Google Cloud Platform. You’ll use the c4a-standard-4 machine type, which provides 4 vCPUs and 16 GB of memory. This VM will host your TimescaleDB application.

Note

For help with GCP setup, see the Learning Path Getting started with Google Cloud Platform .

Provision a Google Axion C4A Arm VM in Google Cloud Console

To create a virtual machine based on the C4A instance type:

  • Navigate to the Google Cloud Console .
  • Go to Compute Engine > VM Instances and select Create Instance.
  • Under Machine configuration:
    • Populate fields such as Instance name, Region, and Zone.
    • Set Series to C4A.
    • Select c4a-standard-4 for machine type.

  • Under OS and storage, select Change, and then choose an Arm64-based operating system image.
    • For this Learning Path, select SUSE Linux Enterprise Server.
    • For the license type, choose Pay as you go.
    • Increase Size (GB) from 10 to 100 to allocate sufficient disk space.
    • Select Choose to apply the changes.
  • Under Networking, enable Allow HTTP traffic and Allow HTTPS traffic. Also add the tag allow-tcp-3000 to enable remote Grafana access.
  • Select Create to launch the virtual machine.

After the instance starts, select SSH next to the VM in the instance list to open a browser-based terminal session.
