Please be aware that for the sake of simplicity, this guide covers a single Zone FiFo install.
Although this is supported and is acceptable for a private server, testing and evaluating FiFo - in a real-world production cloud environment you should deploy in a sensible manner that ensures high availability and data integrity that matches your use case.
It is recommended that you deploy across at least 5 physically separate zones.
FiFo uses LeoFS for storage and requires a minimum of 2 dedicated LeoFS zones. It is recommended that you setup LeoFS first, so that your storage is ready and available for the FiFo zone installation steps.
Now that you're familiar with the install overview, lets move on to FiFo's Requirements.
