Continuous Profiling vs APM: What Are They and When Should You Use Each One?

▤ Summary

This article compares continuous profiling and APM as two complementary observability layers for production systems. It explains that APM helps locate where latency or errors occur across services, while profiling shows which functions or code paths consume CPU or memory. It also outlines when APM alone is enough, when profiling becomes necessary, and why using both can speed root-cause analysis. The piece names several vendors and tools in the observability market and frames the choice as an operational decision for software teams.
