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.
Network
By default, Infrastructure Optimizer schedules workload workers to run in private subnets to protect them from direct external accesses.
Use the following command to ensure that the AWS VPC where Infrastructure Optimizer will run has at least one private subnets with public NAT Gateways:
aws ec2 describe-subnets --filter Name=vpc-id,Values=<vpc_id> --query 'Subnets[?MapPublicIpOnLaunch==`false`].SubnetId'
aws ec2 describe-nat-gateways --filter Name=vpc-id,Values=<vpc_id> --output json | jq '.NatGateways[] | {NatGatewayId, SubnetId, ConnectivityType}'
These commands will provide a list of private subnets suitable for running the Infrastructure Optimizer workload workers.
If no private subnets exist, follow the AWS documentation to create a private subnet and a public NAT Gateway.
Security
A pre-provisioned, user-managed SSH key pair is required to access the Infrastructure Optimizer head node.
For environments with existing PKI setup, the x509 certificates, private key, and optionally, intermediate chain certificates and CA certificates will be also needed.
Compute
Infrastructure Optimizer runs on the following OSes:

EC2 Instance Profiles
The X-Spot 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.
