For more details go to Zing System requirements. At least 2 vCores are needed and adding more improves the throughput.

You can also install the standard Zing packages inside any HVM Linux-based AWS EC2 instance (but not on PV instances). Amazon Linux is preferred for that use case, but RHEL, Ubuntu, Debian or SLES can also be used. Read more about this on Zing on Amazon Linux. Installation on other cloud providers like Google or Azure is also possible as long as the guest OS system is one of the supported by Zing.
If you are not sure if your system is supported and don't won't to read through all those documentation, just go to https://azul.com/zingtrial, our automatic self service page, for downloading the Zing trial installation package. It offers the same functionality as the full version.
