rize.py
Script to analyze reserved instance utilization.
Currently: assumes 1-year heavy utilization reserved instances.
Identifies:
- Reservations that aren't being used (and the total monthly cost/waste)
- Running instances that aren't reserved
- Cost savings if you were to reserve all running on-demand instances
- Time to recoup up-front reservation costs
Supported regions: us-east-1, us-west-1, us-west-2, eu-west-1.
Prerequisites
You'll need to install boto and texttable:
easy_install boto
easy_install texttable
Then configure boto with your AWS key:
cat <<EOF > ~/.boto
[Credentials]
aws_access_key_id = foo
aws_secret_access_key = bar
EOF
Running:
Run with defaults:
./rize.py
Exclude instances with security group matching -e :
./rize.py -e '^ElasticMap.*'
Run in us-west-2:
./rize.py -r us-west-2
List all reserved instances and exit:
./rize.py -l
Operate only on VPC instances/reservations:
./rize.py --vpc
