Summary
In this chapter, we have explored the significance of DEM in achieving observability and how it can help in identifying user issues. We have delved into the AWS services that can be used to measure DEM. Specifically, we have learned how CloudWatch Synthetics operates, its various use cases, and how to set it up using a blueprint and canary recorder. Additionally, we have examined the need for RUM and how it operates, and have gone through the process of setting up an end-to-end RUM for an S3 static website, including how to analyze the output.
In the next chapter, we will navigate into the open source observability landscape offered by AWS. We will explore collecting metrics and traces using the OpenTelemetry (OTel) open standard.
