A is correct As described in the Designing a Connected Vehicle Platform on Cloud IoT Core case study, 1. Google Cloud Dataflow is essential to transform, enrich and then store telemetry data by using distributed data pipelines 2. Cloud Pub/Sub is essential to handle the streams of vehicle data while at the same time decoupling the specifics of the backend processing implementation It now comes down to a choice between 1. Cloud SQL vs BigQuery for analytics. 2. GKE (with or without Anthos) + Cloud Load balancing vs App Engine. For the first point, there is no doubt that BigQuery is the preferred choice for analytics. Cloud SQL does not scale to this sort of data volume (9TB/day + data coming through when vehicles are serviced). For the second point, GKE with Cloud Load Balancing is a better fit than App Engine. App Engine is a regional service whereas, with the other option, you can have multiple GKE clusters in different regions. And Cloud Load Balancing can send requests to the cluster in the region that is closest to the vehicle. This option minimizes the latency and makes the feedback loop more real-time.

Agreed - A. For those with load balancing concerns re: FTP; transport protocol for ftp is TCP, albeit over two TCP ports. GCP Load Balancing supports TCP.

You will need to use (install) an FTP server that supports load balancing. Google Cloud does not offer an FTP server service or software product

App engine is regional https://cloud.google.com/appengine/docs/locations. Case study says it's a global business. which rules out app engine. so we are left with A. "App Engine is regional, which means the infrastructure that runs your apps is located in a specific region, and Google manages it so that it is available redundantly across all of the zones within that region."

As per case study: "They currently have over 500 dealers and service centers in 100 countries."

B missed the global LB. App Engine is regional only. You have to create App Engine in each region and use LB as the front door.

Load Balancer doesn't work on ftp. You need a server to close the connectione and put the file. than the server ftp, can put the file on pub sub etc. so the answer is B

B is correct. We dont have LB that support SFTP traffic. Hence we eleminate A & C We are talking arbore analyzing IoT data = Big Quavery = B.

Answer B, because of Bigquery (Analytics) and AppEngine Flex (custom runtime environments) and the fact that there is no such a thing as Google Container Engine, there is Google Kubernetes Engine.

IMHO it is b). Background: We have in 22 hours 9 TB of ingest data. That makes 113 MB per second. The question is: Why do we have to use for a "simple" transformation of FTP files into Cloud Pub/Sub GKE with multiple clusters around the world? For me it seems to be sufficient to have App Engine Flexible in one region to handle that. We have no highly interactive game where every ms counts concerning the customer experience - we have "only" some vehicles sending data that has to be tranformed and then analysed.

how B? I do not see any LB there and App Engine doesn't support LBs beyond HTTP(s). Answer Is A but B's existence is confusing me much

ultra low latency isn’t required. Whereas A isn’t possible because you can’t use FTP with LB.
