[All Professional Cloud Developer Questions]

You manage an application that runs in a Compute Engine instance. You also have multiple backend services executing in stand-alone Docker containers running in Compute Engine instances. The Compute Engine instances supporting the backend services are scaled by managed instance groups in multiple regions. You want your calling application to be loosely coupled. You need to be able to invoke distinct service implementations that are chosen based on the value of an HTTP header found in the request. Which Google Cloud feature should you use to invoke the backend services?

Service Directory for sure! It's the perfect solution for this use case. Plus, it's just fun to say 'Service Directory' - it's like a superhero name for your APIs!

I think Traffic Director could also work well for this scenario.

I agree, Service Directory makes it easy to invoke different service implementations based on HTTP headers.

Internal HTTP(S) Load Balancing could work, but it doesn't really address the dynamic service selection based on the HTTP header. I'd say Service Directory is the way to go.

Why do you think that? I thought Traffic Director would be the best choice for this scenario.

Hmm, I'm not sure. Anthos Service Mesh also seems like a good choice for managing and routing traffic to the backend services. But Service Directory might be the simpler solution here.

I think I'd go with Service Directory. It seems like the best option to decouple the calling application from the backend services and allow for dynamic service discovery based on the HTTP header.
