Would you rather give meaningful name to your services or cool sounding names like aws greengrass?

I'm starting to look at how to get devices to send data to an endpoint for storage and analysis. I'm looking at AWS iot stuff like core and green grass but then I'm thinking that a REST API could also do the job. I don't need to connect devices to each other (in first iteration). Dont think I need any edge stuff either. Anybody have any experience with this?
