Micro-apps branding [on hold]

Further to this question; We are currently in a large transition from a few monoliths (used mostly internally) to a greater number of micro services. It means that users will now visit many, small, single-page applications (SPA) for the specific task that they are trying to achieve.

Branding the monoliths was easy, we sent a poll to the relevant audience, chose a name and produced a logo. This name then appeared in ITSM, architecture diagrams etc.

Now, with micro-apps, what should be our branding strategy? For example, should it be the same process of a poll and a logo times SPAs? Or a few families of brands (e.g. names metals)?

Real world examples would be highly appreciated.
