AWS Tagging Fundamentals

This section digs into the basics of AWS tags and how they can benefit small and medium-sized businesses (SMBs).

What Are AWS Tags?

AWS tags are metadata labels in the form of key-value pairs that you attach to AWS resources. These tags help identify and categorise resources across your AWS environment. Each resource can hold up to 50 tags, giving you plenty of flexibility for organisation and tracking. For SMBs, they provide a consistent method for labelling resources across AWS services, from EC2 instances to S3 buckets.

Key components of tags include:

• Key: The main identifier, like "Project", "Cost Centre", or "Owner".
• Value: The specific detail, such as "Website Redesign", "MKT-001", or "Jane Smith".

Why Tags Matter for SMBs

Organising Resources
Tags make it easier to keep your AWS environment structured. For example, you can use them to:

• Group resources by project or application.
• Separate test environments from production ones.
• Assign ownership to teams or individuals.

Managing Costs
Tags simplify budgeting and cost tracking by:

• Breaking down expenses by department or project.
• Highlighting unused or redundant resources.
• Enabling cost alerts based on specific tags.

Improving Access Control
Tags can also help tighten security by supporting:

• Role-based access control (RBAC).
• Permissions at the resource level.
• Access policies tailored to specific environments.

Here’s an example of a practical tag structure:

To make the most of AWS tags, consistency is crucial. A well-documented tagging strategy with standard naming conventions ensures your AWS setup stays organised as your business grows.

Setting Up AWS Tags

To make the most of tagging in AWS, start with a well-defined tagging policy and implement it effectively.

Creating a Tagging Policy

Centralise your tagging standards in a single, easily accessible document. Include key tags like Business Unit, Cost Centre, and Environment to help manage costs and organise resources.

To enforce these standards, use tools like AWS Organisations and Service Control Policies (SCPs). Additionally, configure AWS Config rules to ensure compliance and set up AWS CloudWatch alerts to flag any resources that don’t meet the tagging requirements.

Key Tags for SMBs

Here are some tag categories that can simplify resource management for small and medium-sized businesses:

Tag Naming Rules

Consistent naming is crucial for clarity and automation.

Format Guidelines

• Use lowercase for tag keys and camelCase for compound values.
• Keep tag keys under 128 characters and values under 256 characters.
• Allowed characters include letters, numbers, spaces, and symbols like +, -, =, ., _, :, /, and @.

Automation-Friendly Format

Design your tags to work seamlessly with AWS automation tools. A common structure is:

<prefix>-<environment>-<resource_type>-<identifier>

For example: smb-prod-ec2-webserver

This structured approach helps SMBs stay organised, manage costs, and maintain control over their cloud infrastructure.

Cost Control with Tags

Managing tags effectively can help you keep AWS costs under control by providing detailed insights into spending.

Track Costs by Department

Using cost allocation tags allows you to break down expenses in detail.

How to Enable Cost Allocation Tags

Head to the AWS Billing Console and activate both AWS-generated and user-defined cost allocation tags. These tags help you categorise and track spending more effectively.

Generate Monthly Cost Reports

Monthly cost reports can highlight spending trends and help you optimise resource usage. These reports are also essential for conducting detailed analyses in AWS Cost Explorer.

Using AWS Cost Explorer

1. Enable Detailed Billing
   Make sure detailed billing is turned on in AWS Cost Explorer.
2. Create Custom Reports
   Build reports tailored to your needs by focusing on key tag combinations, such as:
   • Spending trends by department (daily or monthly)
   • Project-specific cost breakdowns
   • Resource usage by owner
   • Comparisons by environment (e.g., production vs development)
3. Set Up Budgets
   Use tags to create budgets for departments, projects, or environments. Configure alerts via email or AWS notification services to notify you when spending approaches your set limits.

Tag Automation and Rules

AWS offers tools to streamline tagging processes, ensuring consistency while cutting down on manual work and reducing errors.

Automated Tag Management

AWS Config rules help ensure resources meet tagging requirements. You can set up custom rules to:

• Confirm all resources have the required tags.
• Check that tag values adhere to approved formats.
• Trigger corrective actions for resources that don’t comply.

Using Lambda for Tagging

Lambda functions can automatically assign tags when new resources are created. For instance:

Service Control Policies (SCPs)

At the organisational level, SCPs can enforce tagging rules. These policies can:

• Block resource creation if mandatory tags are missing.
• Limit tag modifications to authorised users.
• Ensure tag values follow standardised formats.

The next step is understanding how tags can enforce compliance and secure access within your AWS environment.

Compliance Through Tags

Tags play a key role in meeting regulatory requirements, such as UK/EU GDPR.

Tracking Compliance with Tags

Specific tags can be used to monitor compliance-related details:

Automated Monitoring for Compliance

AWS Config can be configured to:

• Monitor resources for required compliance tags, send alerts for non-compliance, and log corrective actions.
• Generate compliance reports based on tag data.
• Track remediation efforts using AWS Systems Manager.

Controlling Access with Tags

Tags can also be used with IAM policies to restrict access to sensitive resources. For example, you can allow access to S3 resources only if they are tagged appropriately:

{
    "Effect": "Allow",
    "Action": ["s3:*"],
    "Resource": "*",
    "Condition": {
        "StringEquals": {
            "aws:ResourceTag/DataClassification": "Public"
        }
    }
}
