Is it possible to create a Parameter Store parameter in mutiple region ?

Hello.

Try adding the "--region" option as shown below.

aws ssm put-parameter --name "/dev/service-a/secret-key" --type "SecureString" --value "my-super-secret-secret" --region "ap-northeast-1"

Hi,

if you want to replicate the same parameter (name, value) across multiple regions and manage it from a single central region, this article provides all code and CFN templates to achieve it: https://technology.customink.com/blog/2022/01/10/aws-systems-manager-ssm-cross-region-replication/

Hi,

AWS Systems Manager Parameter Store is hosted in multiple Availability Zones in a single AWS Region, and does not support cross region replication out of the box, so unfortunately you will have to manage it manually.
