Wait, are we really considering Compute Engine for this? Seems outdated.

Not sure if public/private keys are the way to go. What about scalability?

I keep getting confused between the options, but I think Cloud IoT Core aligns best with Google’s best practices for IoT data.

I practiced a similar question, and I think Compute Engine options might not be the best fit for this scenario since they seem more manual.

I'm not entirely sure, but I feel like Google Kubernetes Engine could also work for handling large-scale data ingestion.

I remember we discussed the importance of secure data ingestion, so I think Cloud IoT Core with public/private key pairs might be the right choice.

The SSL Ingress in option A sounds like a good security feature, but I'm not sure if that's the most appropriate solution for this specific use case.

I'm a bit unsure about the differences between the Kubernetes and Compute Engine options. I'll need to review those in more detail to make a confident choice.

I'm leaning towards option B, Cloud IoT Core with public/private key pairs, as that seems to align best with the requirements and Google's recommendations.

Okay, let's think this through step-by-step. The key is to focus on the Google-recommended practices for ingesting data from a large number of connected vehicles.

Personally, I think B) Cloud IoT Core with public/private key pairs is the way to go. It's like putting your data in a vault with a secret handshake. Genius!

I don't know, you guys. I'm kind of leaning towards C) Compute Engine with project-wide SSH keys. Seems like the easiest option, and hey, what could go wrong?
