Answer 1

I don't think you can currently do this in the AWS GUI. But here is a way to list all your instances across all regions with the AWS CLI:

for region in `aws ec2 describe-regions --region us-east-1 --output text | cut -f4`
do
     echo -e "\nListing Instances in region:'$region'..."
     aws ec2 describe-instances --region $region
done

Also, if you're getting a

You must specify a region. You can also configure your region by running "aws configure"

You can do so with aws configure set region us-east-1, thanks @Sabuncu for the comment.

Update

Now (in 2019) the cut command should be applied on the 4th field: cut -f4

A quick bash oneliner command to print all the instance IDs in all regions:

@imTachu solution works well. To do this via the AWS console...

• AWS console
• Services
• Networking & Content Delivery
• VPC
• Look for a block named "Running Instances", this will show you the current region
• Click the "See all regions" link underneath

Answer 5

Every time you create a resource, tag it with a name and now you can use Resource Groups to find all types of resources with a name tag across all regions.

Answer 6

You may use cli tool designed for enumerating cloud resources (cross-region and cross-accounts scan) - https://github.com/scopely-devops/skew

After short configuration you may use the following code for list all instances in all US AWS regions (assuming 123456789012 is your AWS account number).

from skew import scan

arn = scan('arn:aws:ec2:us-*:123456789012:instance/*')
for resource in arn:
    print(resource.data)
