You know, with all these microservices, it's starting to feel like we're playing a game of 'Span the Microservice' instead of just getting the job done. But I'll go with 6 spans.

Okay, let me think this through. The client, load balancer, authentication, billing, resource, and result. Yep, that's 6 spans. Easy peasy!

Aha, I see what's going on here. The client initiates the request, then it goes through 4 different services before getting the result. That's gotta be 6 spans, right?
