In which scenario would you use a web service type in Dynatrace?

Using a web service type in Dynatrace is primarily relevant in scenarios where applications need to handle API-based interactions. This is because web services are designed to facilitate communication between systems over the internet, enabling them to send and receive data via APIs.

When you're monitoring a web service, Dynatrace can track performance metrics, analyze response times, and ensure that the APIs are functioning correctly and efficiently. This includes understanding the interactions between different microservices and identifying potential issues that could impact application performance or user experience.

In contrast, serving static HTML content typically involves delivering pre-built web pages, which does not engage in the dynamic data interactions that a web service would. Similarly, while processing user authentication can involve API calls, it is generally part of a larger framework that may require a dedicated monitoring approach rather than being distinct enough to be classified solely as a web service type. Storing user preferences also falls into the domain of database interactions or user settings management rather than the active communication patterns that define web services. Therefore, for scenarios involving API-based interactions, leveraging a web service type is most suitable.
