Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Usage instructions
WARNING : The region east-us1 must not be used to deploy Cosmian products ! It is only present due to an AWS testing constraint but this region does not allow the deployment of confidential VM for the moment.
Make sure to enable the configuration related to AMD SEV-SNP option located in the advanced details tab within the marketplace deployment page.
As the Cosmian KMS is deployed on top of a Cosmian Verifiable VM, cosmian_vm_agent starts for the first time, it initializes several components:
- It generates a self-signed certificate and sets the CommonName of the certificate to the value of the machine hostname.
- It generates a LUKS container (/var/lib/cosmian_vm/container) and mounts it at /var/lib/cosmian_vm/data. Note that /var/lib/cosmian_vm/tmp is a tmpfs. It is encrypted but it should contain only volatile data since it is erased at each VM reboot. Data in this directory is encrypted due to the fact that the RAM is encrypted.
- It generates the TPM endorsement keys.
It is recommended to configure 1. and 2. on your own for production systems.
The certificate can be changed at will:
- Edit your DNS register to point to that VM.
- Create a trusted certificate using the method of your choice (e.g., Let's Encrypt) or use cosmian_certtool.
- Edit the cosmian_vm_agent configuration file to point to the location of the TLS certificate and private key.
The LUKS container can be regenerated using cosmian_fstool with your own size and password (to store by yourself in a secure location). It is recommended to use an additional backup disk to store the container. You can skip all these first startup steps by setting COSMIAN_VM_PREINIT=0 when starting cosmian_vm_agent.
Once the image is instantiated (on GCP, Azure, or AWS), the <code>cosmian_vm_agent</code> automatically starts as a systemd service when the VM boots.
You can now install any packages or applications you want on the VM.
Your VM is now set and ready.
Finally, please follow the deployment process to configure your KMS properly: https://docs.cosmian.com/deployment/cosmian_vm_kms/
