What costs can be refunded?
This discussion is about a large, unexpected cost overrun on your AWS account, typically in the thousands of dollars. Before we discuss the process, let's review some cost control best practices.
Cost Control Best Practices
Use the AWS Calculator. Before you consider running an AWS service, use the AWS Calculator to estimate the monthly cost. You can select different services and enter the type of usage you expect to use. This allows you to experiment with different sized computers, storage, and other resources. If you need assistance with the AWS Calculator, you can contact the AWS UIUC Team or schedule a meeting with the AWS Office Hours.
Start small. It helps to start with a small resource example that will allow you to test if it meets your needs. Starting with a smaller computer you can see how it performs. Often, small computers work well if it needs to support a few users or a small database.
Use Serverless options. AWS provides several serverless options for computers, databases and other services. Serverless means a computer is only used when needed, and when it is not needed the computer shuts down. Serverless is the best option to help save costs on AWS. This prevents a computer resource from running 24 hours a day.
Use a Savings Plan. Signing up for a Savings Plan can reduce compute costs up to 72%
Set a Monthly Budget with alert emails. When an account is created, the monthly budget is set to $500. You can modify the monthly budget depending on your usage. Email notifications will be sent to the account owner when the monthly spend reaches 80% of the total monthly budget.
Regularly review your expenses with Cost Explorer. Checking your account regularly with Cost Explorer will show expenses for all resources in an easy-to-read graph.
Schedule a review of costs with AWS Office Hours. You can always reach the AWS UIUC team through the AWS Office Hours reservation system. The team is happy to explore cost issues and help explain how to reduce costs.
