Introduction

AWS Organizations enable you to centrally manage and administer your environment as you develop and manage your AWS resources. You may use AWS Organizations to create new AWS accounts and assign resources programmatically, group accounts to organize your operations, apply policies to accounts or groups for administration, and simplify billing by utilizing a single payment option for all of your accounts.

Besides that, AWS Organizations is connected with other AWS services, allowing you to create central configurations, security methods, audit requirements, and sharing resources across your organization's accounts. AWS Organizations is offered at no additional cost to all AWS users.

AWS Organizations Features

AWS Organizations provides the following functionalities:

1. All your AWS accounts are manageable from a single location.

You may group your existing accounts into an organization, allowing you to manage them all from one location. You may establish accounts automatically added to your organization and invite other users to join your group. You may also add policies that apply to any or all of your accounts.

2. Billing for all member accounts is centralized.

AWS Organizations support consolidated billing. You may use your organization's administration account to combine and pay for all member accounts. Management accounts in consolidated billing have access to the billing and account activity information of member accounts in their company. Services like Cost Explorer might utilize this data to assist management accounts in improving their organization's cost performance.

3. Accounts are grouped hierarchically to fulfill financial, security or compliance requirements.

You may organize your accounts into organizational units (OUs) and assign various access controls. For instance, if you have accounts that must only access AWS services that fulfill particular regulatory standards, you may group them into a single OU. You may then apply a policy to that OU that prevents access to services that do not fulfill regulatory criteria. You may nest OUs within the other OUs up to five layers deep, giving you more freedom to build your account groups.

4. Policies to centralize control over the AWS services and API operations available to each account

You may use service control policies (SCPs) as an organization's management account administrator to establish the maximum permissions for member accounts. SCPs let you limit which AWS services, resources, and particular API activities each member account's users and roles may access. You may also specify when access to AWS services, resources, and API operations should be restricted.

5. Integration and support for AWS Identity and Access Management

IAM provides precise control over users and responsibilities in accounts. AWS Organizations extends that control to the account level, allowing you to specify what users and roles in an account or set of accounts may do. The resultant permissions are the natural intersection of what AWS Organizations allow at the account level and what IAM expressly grants at the user or role level inside that account.

6. Integration with other AWS services

To conduct tasks on every account that is a member of an organization, you may combine the multi-account management services provided in AWS Organizations with chosen AWS services. When you allow an AWS service in your organization's member accounts to conduct actions on your behalf, AWS Organizations establishes an IAM service-linked role for that service in every member account. The service-linked part comes with specified IAM permissions that enable the other AWS service to conduct particular actions in your organization and its accounts.

7. Global Access

AWS Organizations is a global service with a single endpoint that works from all AWS Regions. You don't need to select a region to operate in explicitly.

8. Free to Use

AWS Organizations is a free feature of your Amazon Web Services account. You are only charged when using other AWS services from your organization's accounts.

Creating and Managing an Organization

The AWS Organizations console or an AWS CLI command  can be used to conduct the following tasks:

1. Create an Organization: Create your organization with your current account as the management account. Create member accounts inside your organization and invite other users to join.

2. Enable features of your organization: The ideal method of working with AWS Organizations is to enable all functionalities. When you create an organization, you may activate all or a subset of options for billing consolidation. The default setting is to enable all features, which includes Consolidated Billing.

3. Check details of your organization: View information about your company's origins, organizational units, and accounts.

4. Delete the Organization: Delete an organization if you no longer need it.

Managing the AWS Accounts

You may manage your organization's accounts by doing the following tasks:

1. Examine the accounts of your organization.

2. Export a list of all your organization's AWS accounts.

3. As part of your organization, create an AWS account.

4. Create an AWS account for your organization.

5. AWS account deletion

Managing AWS Organizations Policies

Policies in AWS Organizations allow you to apply different sorts of administration to your organization's AWS accounts. When all functionalities are enabled in your organization, you may utilize policies.

The AWS Organizations console shows whether each policy type is activated or disabled. Select the Root in the left navigation pane on the Organize accounts tab. The details pane on the right side of the screen displays all available policy kinds. In that organization's root, the list reveals which are enabled and disabled. If the Enable a type option is available, the type is currently disabled. If a type does have the option to Disable, it is now enabled.

Using AWS Organizations with other AWS Services

You may use trusted access to authorize a certain supported AWS service, known as the trusted service, to conduct actions in your organization and its accounts on your behalf. This includes providing rights to the trusted service but does not affect IAM users' or roles' permissions. The trusted service only establishes service-linked roles when it needs to conduct management activities on accounts and not always in all of the organization's accounts.

Security in AWS Organizations

AWS and you share responsibility for security. The shared responsibility model defines this as security of the cloud and security in the cloud:

Security of the Cloud - AWS is in charge of securing the infrastructure that powers AWS services in the AWS Cloud. AWS also offers services that may be used securely. As part of the AWS compliance processes, third-party auditors regularly examine and verify our security's efficacy. 

Security in the Cloud - The AWS service you use determines your responsibility. Other things to include are the sensitivity of your data, your company's requirements, and applicable laws and regulations.

Logging and Monitoring in AWS Organizations

You should keep an eye on your organization to ensure that all changes are logged. This guarantees that any unexpected changes are investigated and that undesired modifications can be reversed.

AWS Organizations is connected with AWS CloudTrail, a service that keeps track of activities made in AWS Organizations by a user, role, or AWS service. CloudTrail records all AWS Organizations API calls as events, including calls from the AWS Organizations dashboard and code calls to the AWS Organizations APIs.

Using the data gathered by CloudTrail, you may determine the request made to AWS Organizations, the IP address from which it was made, who made it, when it was made, and other data.

Accessing AWS Organizations

You can gain access to AWS Organizations in the following ways:

1. AWS Management Console

The AWS Organizations console provides a browser-based interface for managing your organization and AWS resources. Using the console, you could do any work in your organization.

2. AWS Command Line Tools

You may use the AWS command-line tools to undertake AWS Organizations and AWS actions from your system's command line. Using the command line can be more efficient and handy than working with the terminal. The command-line tools are also beneficial if you create scripts that conduct AWS activities.AWS uses different command-line tools: AWS Command Line Interface and AWS Tools for Windows PowerShell.

3. AWS SDKs

The AWS SDKs include libraries and sample code for various programming languages and environments (for example, Java, Python, Ruby, .NET, iOS, and Android). The SDKs handle cryptographically signing requests, resolving failures, and retrying requests autonomously.

4. AWS Organizations HTTPS Query API

The AWS Organizations HTTPS Query API allows you to access AWS Organizations and AWS programmatically. The HTTPS Query API enables you to send HTTPS queries to the service directly. You must digitally add code to sign requests with your credentials using the HTTPS API.
