Amazon CloudWatch application map now supports un-instrumented services discovery

Application map in Amazon CloudWatch now supports un-instrumented services discovery, cross-account views, and change history, helping SRE and DevOps teams monitor and troubleshoot their large-scale distributed applications. Application map now detects and visualizes services not instrumented with Application Signals, providing out-of-the-box observability coverage in your distributed environment. In addition, it provides a single, unified view for applications, services, and infrastructure distributed across AWS accounts, enabling end-to-end visibility. Furthermore, it provides a history of recent changes, helping teams quickly correlate when a modification occurred and how it aligns with shifts in application health or performance. These enhancements help SRE and DevOps teams troubleshoot issues faster and operate with greater confidence in large-scale, distributed environments. For example, when latency or error rates spike, developers can now investigate recent configuration changes, and analyze dependencies across multiple AWS accounts, all from a single map. During post-incident reviews, teams can use historical change data to understand what shifted and when, improving long-term reliability. By unifying service discovery, dependency mapping, and change history, application map reduces mean-time-to-resolution (MTTR) and helps teams maintain application health across complex systems. _Starting today, the new capabilities in Application Map are available at no additional cost in all AWS commercial regions (except Taipei and New Zealand).
