Cleaning up resources

Once again, we have created a number of resources in our AWS account during the course of the hands-on exercises of this chapter. If not taken down, items such as the managed ElasticSearch cluster could bring about a larger bill than you might like. The Lambda function, which fires every 5 minutes, could eat into your Free Tier allowance, as there are on average 43,800 minutes in a month, so this function would be invocated 8,760 times. Simply delete the resources that you are no longer testing with and delete any CloudFormation stacks that you are no longer using to be sure that your AWS bill stays as low as possible.

Also, remember to cancel your QuickSight subscription, whether it was a free trial or a single-month subscription, so that you do not get a recurring charge for the QuickSight service.
