Tutorial / Cram Notes
AWS Resource Groups allow you to create a group of resources that share one or more tags or portions of tags. This helps you manage and automate tasks on a collection of resources.
Here’s how to create a resource group based on tags:
- Navigate to the AWS Resource Groups console.
- Click on ‘Create Resource Group’.
- Choose the ‘Tag based’ group type.
- Select the resources you want to include in your group by specifying tags.
- Name your resource group and add any desired tags to the group itself.
- Review and create the resource group.
Using AWS CLI to list the resources in a Resource Group:
aws resource-groups list-group-resources –group-name YourResourceGroupName
AWS Organizations
For enterprises with complex organizational structures and billing requirements, AWS Organizations offers a way to manage multiple AWS accounts. You can group accounts into organizational units (OUs) and apply policies centrally.
Steps to organize resources using AWS Organizations:
- Create an AWS Organization from the AWS Management Console.
- Invite existing AWS accounts or create new ones within the organization.
- Organize accounts into OUs based on your operational or billing needs.
- Apply Service Control Policies (SCPs) at the OU or account level to define permissions.
AWS Account Structure
Organizing resources may also involve structuring multiple AWS accounts to segregate environments, such as development, staging, and production, or to separate business units.
An example account structure:
Organization Root
├── Production OU
│ ├── Prod Account 1
│ └── Prod Account 2
├── Development OU
│ ├── Dev Account 1
│ └── Dev Account 2
└── Shared Services OU
└── Logging Account
Tagging Strategy
Another important aspect of resource organization is implementing a consistent tagging strategy. Tags are simple key-value pairs attached to AWS resources that can convey ownership, role, environment type, or any other classification relevant to the resource. Tags can be used for cost allocation, automation, and management purposes.
A sample tagging strategy might include tags like:
Environment
(Prod, Dev, Test)Application
(the name of the application)Owner
(team or individual responsible)CostCenter
(for billing purposes)
You can enforce tagging policies using AWS Organizations’ SCPs to ensure compliance across all accounts.
AWS Config
AWS Config allows you to assess, audit, and evaluate the configurations of your AWS resources. Config Rules can help ensure that resources are tagged correctly and that specific resource configurations meet your organization’s requirements.
For example, a Config Rule to check if instances have a required ‘Environment’ tag:
{
“ConfigRuleName”: “required-tags”,
“Description”: “Checks whether instances have the ‘Environment’ tag.”,
“Scope”: {
“ComplianceResourceTypes”: [
“AWS::EC2::Instance”
]
},
“Source”: {
“Owner”: “AWS”,
“SourceIdentifier”: “REQUIRED_TAGS”,
“SourceDetails”: [
{
“EventSource”: “aws.config”,
“MessageType”: “ConfigurationItemChangeNotification”
}
]
},
“InputParameters”: “{\”tag1Key\”:\”Environment\”}”
}
Cost Allocation Tags
AWS allows you to activate cost allocation tags to make it easier to organize and track AWS costs. Once activated, AWS uses these tags to break down costs in your monthly bill, making it easier to understand where your money is going.
Here are steps to enable cost allocation tags:
- Go to the Billing and Cost Management Dashboard.
- In the navigation pane, choose ‘Cost allocation tags’.
- Activate the desired AWS-generated tags or user-defined tags.
Once these tags are activated, they will appear in the Cost Explorer and Billing Dashboard, allowing for more granular analysis of your costs.
Conclusion
By effectively grouping and tagging AWS resources, you can simplify management tasks, improve security posture, and gain better visibility into your infrastructure costs and performance. These strategies are not only critical for maintaining an orderly cloud environment but also for those studying for the AWS Certified Security – Specialty (SCS-C02) exam, as they form the foundation of any secure and efficiently managed AWS infrastructure.

It continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. With AWS Config, you can review changes in configurations and relationships between AWS resources, making it a valuable tool for security analysis and resource management.
Question: What is the importance of Cost Allocation Tags and how do they tie to resource organization?
Cost Allocation Tags are used to track AWS costs on a more granular level. Once activated, these tags categorize and track your AWS costs by grouping costs into different accounts, applications, teams, or cost centers. This helps in attributing costs to the right departments or projects, aiding in budgeting, cost planning, and optimization efforts.
Question: Could you provide an example of how you might use AWS IAM to manage access to groups of resources?
AWS IAM (Identity and Access Management) allows you to create policies that granularly control access to AWS services and resources. For example, you might attach a policy to an IAM group that grants access to all resources with a specific tag, such as ‘Project: XYZ’. This way, only users within that IAM group can access resources associated with ‘Project: XYZ’, thereby organizing access management along project lines.
Question: What strategies might you employ to ensure AWS resource organization is scalable as a company grows?
To ensure scalable AWS resource organization, strategies may include: consistent and comprehensive tagging policies for new and existing resources, modular and templated infrastructure as code (such as AWS CloudFormation templates), leveraging AWS Organizations for account management, and implementing strong governance policies using AWS Service Catalog and AWS Config for enforcement and compliance.
Question: How can AWS CloudFormation assist with the organization of AWS resources, especially for repeatable deployments?
AWS CloudFormation allows you to model, provision, and manage AWS resources using text files or diagrams. It defines and provisions a collection of related AWS resources (called stacks) that can be consistently and repeatably deployed. CloudFormation can use stack sets to deploy across accounts and regions, helping to ensure that resources are organized consistently across the entire organization.
Question: Can AWS Control Tower aid in managing a multi-account AWS environment, and if so, how?
Yes, AWS Control Tower automates the setup of a baseline environment within AWS that is secure, well-architected, and multi-account based on best practices.
