Synthetic Browser Tests and RUM together primarily help improve what aspect of applications?

The focus of Synthetic Browser Tests and Real User Monitoring (RUM) is to enhance the user experience by specifically targeting the uptime and performance aspects of applications that include user interfaces. Synthetic Browser Tests simulate user interactions in a controlled manner, allowing teams to identify performance issues, detect downtime, and engage in proactive troubleshooting before users encounter problems.

On the other hand, RUM collects and analyzes data from real users interacting with the application in their actual environments, providing insights into how well the application performs in terms of speed, responsiveness, and overall user satisfaction. When used together, these tools give a comprehensive view of application performance from both synthetic and real user perspectives, enabling teams to make informed decisions to improve and optimize user interfaces effectively.

The other options address aspects that are less connected to the primary focus of Synthetic Tests and RUM. Security, for example, while vital, is not the core emphasis of these monitoring tools. Similarly, database performance and integrity, along with cloud scalability, represent different layers of application management that are not directly improved through these particular methods, which center primarily on the user interface experience.
