What does Azure Application Insights do?

Azure Application Insights is a powerful tool designed specifically for monitoring the performance and usage of applications. It provides developers with the ability to gain deep insights into how their applications are performing in real-time. This includes tracking metrics like response times, application failures, and user behavior. By utilizing Application Insights, developers can effectively diagnose issues, understand user engagement, and improve overall application performance.

The value of Application Insights lies in its ability to automatically collect telemetry data from your applications, both web and mobile, making it easier to keep track of critical performance indicators. This information helps in making data-driven decisions when it comes to optimizing applications and enhancing the user experience. Thus, the focus of Application Insights on monitoring and analytics clearly highlights why this option is the right choice.

In contrast, other choices pertain to different functionalities that do not accurately capture the purpose of Application Insights. For example, while deploying new services, managing storage solutions, and building serverless applications are essential aspects of Azure, they fall under different Azure services and capabilities, such as Azure DevOps, Azure Storage Services, and Azure Functions, rather than Application Insights specifically.
