Ubuntu AMIs
Ubuntu maintains a page with the latest AMIs in each region for your convenience and reference.
Rocky Linux
Rocky Linux also maintains a handy page for finding AMIs in each region.
Amazon or other specific vendor AMIs
The AWS console can be rather limiting, but you can find the latest AMI with the awscli tool.
Get a list of Amazon images:
aws ec2 describe-images --owners amazon --filters "Name=name,Values=amzn*" --query 'sort_by(Images, &CreationDate)[].Name'
Use AWS Systems Manager paramater store to find the latest one with the name you want:
aws ssm get-parameters --names /aws/service/ami-amazon-linux-latest/amzn2-ami-hvm-x86_64-gp2 --region us-east-1
Then make sure you always use the latest when launching an instance:
aws ec2 run-instances --image-id $(aws ssm get-parameters --names /aws/service/ami-amazon-linux-latest/amzn2-ami-hvm-x86_64-gp2 --query 'Parameters[0].[Value]' --output text) --count 1 --instance-type m4.large
