Rightsizing can also assist you in reducing the number of third-party agents needed to monitor the resources. Once again, this can help with the cost reduction. Datadog, for example, charges based on the number of instances, so the more nodes there are, the more money there is. Splunk charges a daily fee based on the amount of data that the Splunk instance indexes. There is a data transfer fee if data is transferred to a different region for Splunk to index than where the application is located.
