Infrastructure Monitoring is the process of identifying what's affecting system and application performance using data. It gathers data on the health and performance of servers, virtual machines, containers, databases, and other backend components of the tech stack. Engineers can use an infrastructure monitoring tool to visualize, analyse, and alert on metrics to see if a backend failure is affecting users.

Monitoring is critical not only for software operations but also for business outcomes and long-term objectives. When critical systems fail to work as expected, it can be damaging to business operations and have a negative influence on customers. IT teams should be notified when a server crashes, but best practices should go beyond that.
