Cloud application performance management (CAPM or cloud APM) is the process of monitoring resources that support application program performance in private and hybrid cloud environments. An important goal of any CAPM initiative is to provide administrators with the ability to identify a poor user experience (UX) quickly so the cloud service can be turned off until the performance issue has been resolved.
Measuring the user experience for public cloud-hosted applications usually requires an intelligent agent to be placed on the application server to monitor application response time. CAPM tools can then be used to combine data from disparate monitoring silos into a correlation engine and dashboard. The dashboard makes audit logs easier to read and saves IT staff from memory-dependent and error-prone manual correlation and analysis.
As organizations begin to move enterprise applications to the cloud, the need for a tool that monitors and manages the performance and availability of applications across a distributed computing environment has become a must-have. Some tools even include predictive components to alert the administrator as to where potential problems exist and prescriptive components to automate a solution.
