Welcome to Infrastructure Optimizer! 🎉 👏
We are excited to help you with maximizing your cloud resource efficiency and savings!
Before you begin, use this checklist to confirm that your environment satisfies the specifications required to operate Infrastructure Optimizer.
| Info |

The pre-check commands will require the IAM principal to have at least the |
...
Network
By default, Infrastructure Optimizer schedules workload workers to run in private subnets to protect them from direct external accesses.
Use the following command commands to ensure that the AWS VPC where Infrastructure Optimizer will run has at least one private subnets subnet with public NAT Gateways.
Check private subnets that are suitable for running the Infrastructure Optimizer workload Workers:
| Code Block | language | bash
|---|
aws ec2 describe-subnets --filter Name=vpc-id,Values=<vpc_id> --query 'Subnets[?MapPublicIpOnLaunch==`false`].SubnetId'
|
Check whether there is a public NAT Gateway attached:
| Code Block | ||
|---|---|---|
| ||
aws ec2 describe-nat-gateways --filter Name=vpc-id,Values=<vpc_id> --output json | jq '.NatGateways[] | {NatGatewayId, SubnetId, ConnectivityType}' |
...
If no private subnets exist, follow the AWS documentation to create a private subnet and a public NAT Gateway.
...
| Info |
|---|
EKS only: the Infrastructure Optimizer must run in the same VPC as the EKS cluster |
Security
...
A pre-provisioned, user-managed SSH key pair is required to access the Infrastructure Optimizer head nodeManagement Server.
| Info |
|---|
OPTIONAL: Follow the AWS EC2 documentation to generate a SSH key pair. |
For environments with existing PKI setup, the x509 certificates, private key, and optionally, intermediate chain certificates and CA certificates will also be also needed.

EC2 Instance Profiles
The X-Spot controllers and workers Infrastructure Optimizer Controllers and Workers require a set of IAM permissions to manage and scale your workloads efficiently. Use this CloudFormation template to create the EC2 instance profiles.
