What is AWS budget used for?

TUTORIAL

Overview

In this tutorial, you will learn how to control your costs while exploring AWS service offerings using the AWS Free Tier. In addition, you will learn to use AWS Budgets to set up a cost budget to monitor any costs associated with your usage.

The AWS Free Tier is a discount program that lets you gain free, hands-on experience with AWS products and services. All new AWS accounts include the Free Tier so you don't have to sign up for it, allowing you to try out the services you need to build your workloads from day one. With over 100 services in the Free Tier, you can do lots of exploring at a reasonable cost, or even for free.

Monitoring your service usage and associated costs while you are exploring and scaling your usage of AWS is often cited as a top concern. To make sure you don't exceed the Free Tier usage thresholds and your overall budget, we recommend using AWS Budgets. With the cost control features of AWS Budgets, you can create custom cost budgets that alert you when you exceed your budgeted threshold. In this tutorial, you will learn about the AWS Free Tier offering, discover how AWS Budgets monitors your Free Tier usage by default, and how to create a total monthly cost budget that alerts you when you exceed, or are forecasted to exceed, your budget.

It is a best practice to create a total monthly cost budget for each AWS account you use. AWS Budgets has a Free Tier limit of 62 budget days per month, so creating a single budget falls within the AWS Free Tier limit. As the name implies, AWS Free Tier-eligible service usage is free.

Step 1: Explore the AWS Free Tier

a. Access the AWS Free Tier page

Open the Free Tier page, so you can keep this step-by-step guide open. On the AWS Free Tier page, under the AWS Free Tier Details header, choose the 12 months free link.

b. Explore 12 months free offers

c. Access the Always free page

On the AWS Free Tier page, choose the Always free link to view the Always free offers.

d. Explore Always free offers

As the name suggests, these free tier offers do not automatically expire at the end of your 12-month AWS Free Tier term and are available to all AWS customers.

Notable Always free offers include some level of free usage for AWS Lambda, Amazon DynamoDB, Amazon CloudWatch, and many other useful services.

e. Access the Free trials page

On the AWS Free Tier page, choose the Free trials link to view the Free trials offers.

f. Explore trial offers

Step 2: Sign up for AWS (or sign in)

There is no additional charge associated with using the AWS Billing Console for this tutorial. The resources you create in this tutorial are Free Tier eligible. The button and link to the right open a new tab so you can follow this tutorial in the AWS console.

Step 3: Review your spend and Free Tier usage

In this step, you will use the AWS Billing Console to review your overall AWS spend and Free Tier usage.

a. Access the billing dashboard

After you have logged in to your account, from the account menu, choose Billing Dashboard.

b. Review your billing dashboard

Once you reach the AWS Billing Dashboard page, you can view a summary of your month-to-date costs in the AWS Summary section, as well as the cost trend for your top five services for the most recent three to six closed billing periods in the Cost trend by top five services section.

c. Access all your Free Tier usage

To dive deeper into your Free Tier eligible usage, choose Free Tier from the left navigation pane.

d. Analyze all your Free Tier usage

In the Summary section on the AWS Free Tier page, all of your usage of services in the Free Tier are listed. In addition to your Current usage, your forecasted service usage by the end of the month is detailed in the Forecasted usage column.

In the example screenshot, note that the forecasted usage of EC2 is 2 GB-mo. Exceeding the limit of the Free Tier generally results in a billable charge.

e. Modify your AWS Free Tier Usage Limit email alerts

By default, most accounts are automatically opted in to receive AWS Free Tier Usage Limit email alerts when their service usage exceeds 85% of a given Free Tier usage limit.

To change who gets these email alerts, choose Billing Preferences from the left navigation bar.

To opt other people in to receive Free Tier Usage Alerts, in the Email Address field, add their email address and choose Save preferences.

Step 4: Set up a cost budget

In this step, you will set up a cost budget in the AWS Billing Console using AWS Budgets. As part of your cost budget, you will set up three notifications: one for if your costs reach 80% of your budget, one for if your costs are forecasted to exceed your budget, and one if your costs do exceed your budget.

a. Create budget

From the navigation menu on the left, select Budgets then choose Create a budget on the AWS Budgets console page. 

b. Choose budget type

On the Choose budget type page, choose Cost budget under Budget types.

c. Set budget details

On the Set your budget page, edit the Budget name field to read MyMonthlyBudget.

In the Set budget amount section, keep the default selections for Period, Budget renewal type, Start month, and Budgeting method. Enter $100 in the Enter your budgeted amount ($) field.

In the Budget scope section, you can use these features to create budgets that track costs associated with a particular set of AWS services, linked accounts, tags, or other usage dimensions. For this tutorial, keep these values as the default and choose Next.

d. Configure alert for when actual cost exceeds 80% of budget threshold

On the Configure alerts page, you can have AWS Budgets contact you and others by email when budget conditions are met.

Choose Add an alert threshold.

Configure the alert to be triggered when actual costs are greater than 80% of budgeted amount, as shown in the screen shot. Add your email address and the email address of anyone who should receive this alert in the Email recipients field.

e. Configure alert for when actual cost exceeds your budget

From the Configure alerts page, choose Add alert threshold.

Configure this alert to be triggered when forecasted costs are greater than 100% of the budgeted amount, as shown in the screen shot. Add your email address and the email address of anyone who should receive this alert in the Email recipients field.

f. Configure alert for when actual costs exceed your budget

From the Configure alerts page, select Add alert threshold.

Configure this alert to notify you when actual costs are greater than 100% of budgeted amount. Add your email address and the email address of anyone who should receive this alert in the Email recipients field.

g. Attach actions (optional)

Choose Next to view the attach actions page.

A budget action allows you to define and trigger cost-saving responses to reinforce a cost-conscious culture. You have the option to attach actions that run whenever your alert threshold has been exceeded, such as stopping an EC2 instance from incurring any further costs. You can select the alerts to which you would like to attach actions, then define these actions. 

Choose Next to review the budget details on the Review page.

Review your budget and then choose Create budget to create the budget and alerts.

After the budget has been created, you see a list AWS Budgets you have created. It is a best practice to create a total monthly cost budget for each AWS account that you use.

You can create up to 62 budget days per month using the AWS Budgets service within the Free Tier limit. After that, you simply pay as you go to create additional budgets.

h. Inspect your new budget

To dive deeper into your budget details, select your new budget.

From there, you can view your budget details, access a budget performance summary, and inspect your historical budget performance.
