AWS Organizations

AWS Organizations is a Policy-based management for multiple AWS accounts.

About AWS Organizations

AWS Organizations offers policy-based management for multiple AWS accounts. With Organizations, you can create groups of accounts, automate account creation, apply and manage policies for those groups. Organizations enables you to centrally manage policies across multiple accounts, without requiring custom scripts and manual processes.

Using AWS Organizations, you can create Service Control Policies (SCPs) that centrally control AWS service use across multiple AWS accounts. You can also use Organizations to help automate the creation of new accounts through APIs. Organizations helps simplify the billing for multiple accounts by enabling you to setup a single payment method for all the accounts in your organization through consolidated billing. AWS Organizations is available to all AWS customers at no additional charge. More information can be found here.

Using AWS CloudFormation StackSets With AWS Organizations

Use AWS CloudFormation StackSets to roll out Cloudaware CloudFormation stack over multiple AWS accounts in your AWS Organization and allow Cloudaware to collect AWS Organization Sub-Accounts.

Requirements

• Ensure that you are using AWS Organizations. Read more

• Ensure all features are enabled in your AWS Organization. NOTE: this action is irreversible! Read more

Pre-configuration

1. Sign in to AWS Console as an administrator.

2. Enable trusted access with AWS Organizations:

2.1. Select CloudFormation under Management & Governance.

2.2. Select StackSets. Click Enable trusted access.

Once it is done, StackSets creates the necessary IAM roles in the AWS Organizations master account and target accounts where stack instances will be deployed.

The IAM service-linked role created in the Organization master account has the suffix CloudFormationStackSetsOrgAdmin. You can modify or delete this role only if trusted access with AWS Organizations is disabled. 

The IAM service-linked role created in each target account has the suffix CloudFormationStackSetsOrgMember. You can modify or delete this role only if trusted access with AWS Organizations is disabled, or if the account is removed from the target organization or organizational unit (OU).

StackSet Creation

1. Log in to your Cloudaware account → Admin → Amazon Organizations & Accounts. Click +Add.

2. Select 'Using IAM Role'. Download the Cloudaware CloudFormation template ensuring the following permissions are in place:

"organizations:Des*"
"organizations:Li*"

3. Gо back to AWS Console. Select Services → CloudFormation under Management & Governance → StackSets.

4. Click Create StackSet.

5. Select 'Template is ready' and 'Upload a template file'. Click Choose file to upload the Cloudaware CloudFormation template you downloaded earlier. Click Next.

6. Give a name to the stack set. Replace 'auto-generate' role with a custom Role Name in CloudAware Role Name. Insert External ID*.

*Get External ID generated by clicking ‘Generate Random’ button in 'Add Amazon Details' form in Cloudaware.

7. Select the policies to be enabled. Click Next.

8. Select 'Service-Managed Permissions'*. Click Next.

*If you prefer using Self-Managed permissions, set up:

• AWSCloudFormationStackSetAdministrationRole in the master account using the template https://s3.amazonaws.com/cloudformation-stackset-sample-templates-us-east-1/AWSCloudFormationStackSetAdministrationRole.yml

• AWSCloudFormationStackSetExecutionRole which trusts the root account in each(!) sub-account using the template https://s3.amazonaws.com/cloudformation-stackset-sample-templates-us-east-1/AWSCloudFormationStackSetExecutionRole.yml

9. Optional: set deployment options*. Click Next.

*You can limit the stackset deployment to specific OUs to limit account discovery in the AWS Organization. Read more to learn how to specify the OUs as deployment targets. 

IMPORTANT: If you already have a specific OU onboarded by Cloudaware and would like to add another one(s) - please create a stackset with new OU(s) specified using the same Role Name and External ID as you used when adding your first OU.

10. Review the stackset details. Click Submit. Wait for the stackset to be created.

11. Contact your dedicated account manager at tam@cloudaware.com to provide the custom Role Name and External ID used during the stackset creation, along with your AWS Organization Master Account ID.

The auto-collection of AWS Organizational Sub-Accounts in Cloudaware may take time.

Identify AWS Organizational Accounts That Got Onboarded Successfully

1. In Cloudaware navigate to AMAZON WEB SERVICES → Security, Identity, Compliance → Organizations.

2. You should see at least one AWS Organization and N number of AWS Organizational Accounts.

Identify AWS Organizational Accounts That Didn't Get Onboarded Successfully

1. In Cloudaware menu navigate to AMAZON WEB SERVICES → Security, Identity, Compliance → AWS Organizational Accounts.

2. Click Browse Objects:

3. Paste the following query and click Search:

`Deleted From AWS` equals null -> `AWS Organization Account Name` ASC, `Account`.`Account Name` as "Actual Account", `Account ID`, `Email`, `Joined Method`, `Joined Timestamp`, `Parent Root ARN`, `Status`

Any AWS Organizational Account where 'Actual Account' is blank can't be automatically added since Cloudaware is unable to assume its IAM role.

Troubleshooting

If you do not see any AWS Organizations, there are two possible reasons:

1. Insufficient permissions on AWS Organizations Master Account.

2. AWS Organizations Master Account has not been added to Cloudaware.

If AWS Organization Master Account has been added to Cloudaware but auto-collection doesn't take place, check if Role Name and External ID are custom as they shouldn't be left auto-populated by Cloudaware during the StackSet creation.
