What is a strong justification for adopting a Real User Monitoring Tool?

A strong justification for adopting a Real User Monitoring (RUM) Tool is that it provides invaluable insights into user interactions and experiences with your application, particularly when a new front-end web framework is being implemented. When developers transition to a new front-end framework, they often seek to optimize performance, loading times, and overall usability. A RUM tool allows you to collect data directly from users in real-time, giving you the ability to monitor performance metrics, understand how users are navigating the application, and identify any areas causing friction or delay.

This capability is particularly beneficial during the early stages of deploying a new framework, as it helps in evaluating whether the changes lead to improvements in user experience. By capturing how real users interact with the new framework, organizations can make informed decisions based on actual performance data rather than assumptions.

The other scenarios, while relevant to broader application performance management strategies, do not specifically highlight the immediate need for a RUM tool in the same way that adopting a new front-end framework does. Migration to microservices or cloud might emphasize the need for monitoring overall system health or infrastructure performance but not necessarily focus on the user experience aspect as directly as a change in front-end technology. Similarly, having no plans to update a mobile application does not present
