QuestionQ3

Designing data processing systems

You run a logistics company and want to make event delivery from vehicle-based sensors more reliable. You operate small data centers worldwide to capture these events, but the leased lines connecting your event-collection infrastructure to your event-processing infrastructure are unreliable and have unpredictable latency. You want to resolve this in the most cost-effective manner. What should you do?

Explanation

Cloud Pub/Sub provides managed, asynchronous event ingestion that decouples publishers from downstream processing and is designed for scalable, reliable event delivery. Publishing directly from the data-acquisition devices removes the leased-line dependency without the operational cost of self-managed Kafka clusters or the expense of Cloud Interconnect. Pub/Sub is also a documented fit for streaming data from IoT devices and sensors.
