Even though the benefits of APM are well established, the rise of cloud-native applications has made it more challenging to do well. For example, cloud-native apps generate far greater quantities of telemetry data because they are made up of a myriad microservices that dynamically spin up and spin down in the background. Each of these microservices exists for a very short period and generates its own telemetry data, adding to the overall signal noise. When this happens, it becomes more difficult to find the most important events taking place within your application infrastructure.
