In the context of distributed cloud applications, utilizing application insights is crucial for tracking performance. Application insights provide extensive monitoring capabilities that allow developers and operators to collect, analyze, and visualize key performance metrics and telemetry data from applications. This includes tracking application requests, server requests, dependency calls, exceptions, and more, all in real-time.

By implementing application insights, teams can gain deep insights into how their applications are performing under different loads and functionalities, helping them identify slowdowns, bottlenecks, and areas for improvement across various components of a distributed system. This level of monitoring is essential for maintaining optimal performance, especially in a cloud environment where multiple services can interconnect and may have varying performance characteristics.

The use of application insights also facilitates proactive performance management by providing alerts and logging capabilities which can notify teams of issues as they arise, enabling quicker responses and better user experiences. Moreover, this tool's integration with other Azure services allows for a comprehensive view of application health and user behavior, which is invaluable for ongoing optimizations and debugging.

This choice is particularly significant compared to other strategies. Resource tagging helps in managing and categorizing resources but does not directly contribute to performance tracking. Vertical scaling pertains to increasing resources for a single instance rather than monitoring distributed components. Load
