Google Cloud Digital LeaderSecurity and operations with Google CloudMedium
A startup is building a new IoT platform on Google Cloud. They need a way to manage and authenticate a large fleet of IoT devices, securely connect them to the cloud, and ingest telemetric data for processing. Which Google Cloud service is specifically designed to handle device registration, authentication, and communication for IoT solutions?
- ACloud Functions
- BCloud Pub/Sub
- CCloud IoT Core
- DApp Engine
Show answer & explanationAnswer & explanation
Correct answer: C. 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, making it perfect for IoT platforms.
Why the other options are wrong
- A. Cloud Functions is a serverless compute platform for event-driven functions, not for managing IoT devices.
- B. Cloud Pub/Sub is a messaging service often used with IoT Core for data ingestion, but it doesn't handle device management itself.
- D. App Engine is a platform-as-a-service for web applications, not for IoT device management.
Cloud IoT Core
Cloud IoT Core is a fully managed service that enables you to easily and securely connect, manage, and ingest data from millions of globally dispersed IoT devices.
- Provides secure device connection and authentication.
- Supports standard protocols like MQTT and HTTP.
- Integrates with Google Cloud services like Pub/Sub for data ingestion.
- Offers device management features (registration, monitoring).
Memory trick: IoT Core connects the devices, big or small.
