Application Performance Monitoring (APM) was effective in controlled on-premises environments but fails to meet the demands of modern cloud applications using microservices and APIs. As applications increasingly operate across multiple platforms and providers, APM's limitations become evident, particularly when users experience slow load times due to external factors such as ISP issues or CDN delays, none of which APM monitors effectively. In light of these challenges, experts suggest shifting towards Internet Performance Monitoring (IPM) to achieve comprehensive visibility required for maintaining reliability and user satisfaction in a digital-first world.
APM has been a cornerstone of IT operations, tracking application health, but modern applications, built on cloud services and APIs, challenge its effectiveness.
Mitch Ashley emphasized that traditional APM fails to account for critical external factors like ISP congestion, which can impact user experience without raising alerts.
Modern applications span multiple providers and geography, making APM's capability of tracking backend performance insufficient for understanding user experience.
The shift towards Internet Performance Monitoring (IPM) is essential for true visibility and reliability in cloud-centric environments.
