AWS Organizations

AWS Organizations
AWS Organizations allows you to consolidate multiple AWS accounts into one organization that can be centrally managed.
AWS Organizations offer consolidated billing and account management capabilities, which allow you to better meet your budgetary, security and compliance requirements.
Administrators can create new accounts in an organization or invite existing accounts to join.
AWS Organizations allows you to automate AWS account creation and management and to provision resources with AWS CloudFormation Stacksets.
AWS security services policies and management can help you maintain a secure environment
Access to AWS resources and services can be controlled by the government
Centrally manage policies across multiple AWS account accounts
Audit your environment to ensure compliance
With consolidated billing, you can view and manage your costs.
AWS Organization Features: Configure AWS services across multiple accounts
Centralized management all your AWS accounts

Consolidated billing for all member accountConsolidated billing is an AWS Organizations feature.
The master account can be used to consolidate all member accounts and pay them.
To meet compliance, budgetary, security or compliance needs, accounts can be grouped in hierarchical groups. Each OU can be attached with different access policies.
You can also nest OUs to a depth of up to five levels. This allows you flexibility in structuring your account groups.
Access to AWS services and API actions can be controlled by an administrator of an organization. Each member account can have access to the API actions and AWS services that they can access.
Organization permissions can override account permissions. This restriction even applies to administrators of member accounts within the organization.
AWS Organizations can block access to any API action or service for a member’s account. This means that a user or role in the account can’t access any API action or service prohibited even though an administrator of the member account has granted such permissions in an IAM Policy.
Integration and support for AWS IAMIAM allows for granular control of users and roles within individual accounts.
AWS Organizations extends that control to the account-level by giving you control over who can use and what roles an account or group of accounts can do.
Only the AWS Organizations and IAM policies allow access to users.
The resulting permissions represent the logical intersection between what is allowed at the account level by AWS Organizations and what permissions are explicitly granted at the user level or role level by IAM.
If one of these blocks an operation, the user cannot access it.
Integration with other AWS Services: Select AWS services can allow you to access accounts and perform actions on resources.
AWS Organizations creates an IAM-linked role in each member account for any service that is configured and authorized to access the organisation.
Service-linked roles have predefined IAM permissions which allow the other AWS services to perform specific tasks within the organization and its accounts.
All accounts within an organization automatically have a service linked role created. This allows the AWS Organizations service create the service-linked roles required for AWS services.
These service-linked roles are accompanied by policies that allow the service to only perform the required tasks
Data replication that is eventually consistent with AWS Organizations is eventually consistent.
