Launch EC2 with storage requirements

Question

I have to launch an EC2 instance, running RHEL 8, with some storage requirements. And I was wondering how to set it up.

1. \>= 60 GB free storage for requirements:
     -   \>= 50 GB of free storage on the partition that contains /var/lib/. The partition mountpoint should not have the noexec option.
     -   \>= 5 GB of additional space in /var/log
     -   \>= 5 GB of additional space in /var/lib/
2. \>= 500 GB of dedicated storage

Answer

It depends on whether you want those directories as separate partitions/file systems or not (in order to limit their growth). If you want a single large filesystem then you can launch an EC2 instance with an EBS volume of a size that meets your requirements (60 + 50 + 5 + 5 + 500 = 620 GB).

But you can also launch the instance with four EBS volumes of appropriate sizes and mount them using the options that you want - or any option in between. It's completely up to you.

Note that you can [expand EBS volumes if you need to](https://repost.aws/questions/QUD-McikY1QwmFsC5BtZFF9g/extending-aws-ebs-volumes).
