Answer 1

You may find useful new EC2 instance family equipped with local NVMe storage: C5d.

See announcement blog post: https://aws.amazon.com/blogs/aws/ec2-instance-update-c5-instances-with-local-nvme-storage-c5d/

Some excerpts from the blog post:

• You don’t have to specify a block device mapping in your AMI or during the instance launch; the local storage will show up as one or more devices (/dev/nvme*1 on Linux) after the guest operating system has booted.
• Other than the addition of local storage, the C5 and C5d share the same specs.
• You can use any AMI that includes drivers for the Elastic Network Adapter (ENA) and NVMe
• Each local NVMe device is hardware encrypted using the XTS-AES-256 block cipher and a unique key.
• Local NVMe devices have the same lifetime as the instance they are attached to and do not stick around after the instance has been stopped or terminated.
