Welcome to your first step towards cloud efficiency and savings with Infrastructure Optimizer!
Before you begin, use this checklist to confirm your environment satisfies the specifications required to operate Infrastructure Optimizer.
Network
Component | Requirements |
VPC | Contains at least one private subnet. Check with this command: aws ec2 describe-subnets --filter Name=vpc-id,Values=<YOUR VPC ID> --query 'Subnets[?MapPublicIpOnLaunch==`false`].SubnetId' |
NAT Gateway | Has a NAT Gateway with public connectivity. Verify with this command: aws ec2 describe-nat-gateways --filter "Name=vpc-id,Values=<YOUR VPC ID>" | jq '.NatGateways[] | {NatGatewayId, ConnectivityType}'
|
Security
Component | Details |
SSH Key | This will be used to attach to the Management Server. |
Trusted Certificate | Required only if deploying in a private environment. |
Compute
Component | Requirements |
Operating System | Using Linux variants. |
Permissions
We understand that cloud control and security are important to you.
To use Infrastructure Optimizer and start saving right away, you must create the following least-privilege IAM roles:
This policy needs to be attached to the user who performs the installation and operation.
