4 Ways to Use AWS Cost Allocation Tags for Cost Control

What are AWS Cost Allocation Tags?

If your business utilizes Amazon Web Services (AWS), you’re probably always looking for methods to reduce expenses and maximize use. Utilizing cost allocation tags is one approach to accomplish this. With the use of smart cost allocation tags, you can easily track and control your AWS usage by allocating particular charges to particular projects or business units.

Companies can use cost allocation tags to fully understand where their funds are being spent and make more educated decisions regarding AWS consumption. In this post, we’ll examine how cost allocation tags can reduce expenses for businesses while enhancing their use of AWS services.

Costs Associated with AWS

Understanding AWS costs is a crucial step in being able to effectively use cost allocation tags to save resources. There are three main categories of costs associated with AWS: compute, storage, and data transfer.

• Compute Costs
  Compute costs refer to the cost of using AWS’s virtual machines and other computing resources. This includes the cost of running instances, provisioned capacity, and auto-scaling. Compute costs are based on the type and number of vCPUs and the amount of memory used. Additionally, costs can be reduced by using Spot Instances, which allow businesses to pay a discounted rate for instances that are used for a longer period of time.
• Storage Costs
  Storage costs refer to the cost of storing data on AWS S3 and EBS services. S3 is a simple storage service that allows businesses to store and retrieve data at any time and from anywhere. EBS is a block-level storage service that allows businesses to store data in a highly available and scalable way. Storage costs are based on the amount of data stored, the number of requests made, and the amount of data transferred out. These costs can be reduced by using infrequent access storage options, and by using data compression techniques.
• Data Transfer Costs
  Data transfer costs refer to the cost of moving data in and out of AWS. This includes data transfer between AWS regions, between an AWS service and the internet, and between an AWS service and a customer’s on-premises data center. Data transfer costs can be reduced by using AWS Direct Connect, which allows businesses to establish a dedicated network connection to AWS, and by implementing data compression techniques.

AWS Cost Allocation Tags

How do they work?

When you create a cost allocation tag, you assign a specific key-value pair to a resource or a group of resources. These tags can be applied to a wide range of AWS services, including EC2 instances, Elastic Block Store volumes, and S3 buckets. Once the tag is applied, the associated costs will be grouped together and can be viewed in the AWS Cost Management Console.

How to Create Cost Allocation Tags in AWS?

Cost allocation tags allow you to assign specific costs to specific projects or business units.

• To create a cost allocation tag, you’ll need to go to the AWS Cost Management Console and select “Tags” from the menu.
• From there, you can select “Tags” from the menu and create a new tag. When creating a tag, you’ll need to provide a key and a value. The key is a label for the tag and the value is the specific project  or business unit that you want to assign the costs to.

• Once you’ve created your tags, you can start applying them to your resources. You can do this by selecting the resources that you want to tag and then selecting the “Add/Edit tags” option. You can also use Tag Editor to apply tags to multiple resources at once.

Types of Cost Allocation Tags & Their Applications

There are several types of cost allocation tags that can be used to track and manage costs on AWS. These include:

1. Project tags: These tags are used to assign costs to specific projects or business units. For example, a company may create a tag called “Project A” and assign all the costs associated with that project to that tag. This way, the company can see exactly how much money Project A is costing them.
2. Environment tags: These tags are used to assign costs to different environments, such as development, staging, or production. This allows companies to see the costs associated with each environment and make more informed decisions about their usage.
3. Service tags: These tags are used to assign costs to specific services, such as EC2 or Amazon S3. This allows companies to see the costs associated with each service and make more informed decisions about their usage.
4. Owner tags: These tags are used to assign costs to specific individuals or teams within an organization. This allows companies to see the costs associated with each individual or team and make more informed decisions about their usage.

It’s important to note that the type of tag you choose will depend on your business goals and objectives. For example, if you’re primarily interested in understanding the costs associated with different projects, project tags may be the best choice. If you’re more interested in understanding the costs associated with different environments, environment tags may be a better choice.

AWS Cost Allocation Tags Best Practices

When creating and using cost allocation tags, it’s important to keep in mind that the key-value pairs should be meaningful and consistent across the organization. This will make it easier to analyze and report on the data later on. Additionally, it’s important to review and update tags regularly to ensure that they remain accurate and relevant.

• Establish a consistent tagging strategy across all resources. Define clear naming conventions and enforce them rigorously. For example, use tags like “Environment” (dev, test, prod), “Department” (finance, marketing, etc.), “Owner” (individual or team responsible), etc to your resources.
• AWS Resource Groups can be created based on tags, making it easier to manage and analyze resources that share common attributes. You can create resource groups for cost analysis, monitoring, and access control purposes, which helps in organizing resources logically.
• Ensure that all relevant resources are tagged consistently and accurately. This includes EC2 instances, RDS databases, S3 buckets, and other AWS services. Even transient resources like Lambda functions or temporary EC2 instances should be tagged appropriately to track their costs.
• Regularly audit and monitor tag usage within your AWS environment. Identify untagged resources and take corrective actions to tag them properly. AWS provides tools like AWS Cost Explorer and AWS Cost and Usage Report (CUR) that allow you to analyze cost allocation based on tags.

Conclusion

AWS Cost Allocation Tags are a powerful and versatile tool for managing and optimizing costs on the AWS platform. By using tags to track usage and allocate costs, organizations can gain valuable insights into their spending and make informed decisions about resource allocation and optimization. Whether you are managing a small-scale deployment or a large enterprise environment, cost allocation tags provide a flexible and scalable solution for tracking costs and managing budgets.

Overall, AWS cost allocation tags can help users achieve greater cost transparency, reduce waste, and optimize their spending on the AWS platform. By implementing a thoughtful tagging strategy and leveraging the many tools and services available for managing costs on AWS, organizations can achieve greater efficiency, agility, and cost savings.
