Google Cloud Digital LeaderSecurity and operations with Google CloudMedium
An IoT startup is building a new IoT platform on Google Cloud. They need a way to manage and authenticate thousands of devices, securely ingest device telemetry, and send commands back to the devices. They also require robust security features like device authentication and authorization. Which Google Cloud service provides a fully managed solution for connecting, managing, and ingesting data from IoT devices?
- ACloud IoT Core
- BCloud Dataflow
- CCloud Pub/Sub
- DCloud Functions
Show answer & explanationAnswer & explanation
Correct answer: A. Cloud IoT Core
Cloud IoT Core is a fully managed service for connecting, managing, and ingesting data from large numbers of globally dispersed IoT devices, providing secure device authentication and communication.
Why the other options are wrong
- B. Cloud Dataflow is a service for stream and batch data processing, typically used after data ingestion.
- C. Cloud Pub/Sub is a messaging service that IoT Core uses for data ingestion, but it doesn't manage devices itself.
- D. Cloud Functions are serverless compute for event processing, not a device management platform.
Cloud IoT Core
Cloud IoT Core is a fully managed service that allows you to securely connect, manage, and ingest data from millions of globally dispersed IoT devices.
- Provides device registration, authentication, and authorization.
- Supports standard protocols like MQTT and HTTP.
- Securely ingests data and publishes it to Cloud Pub/Sub.
- Enables sending commands back to devices.
Memory trick: IoT Core is the central hub for all your smart devices.
