AWS Greengrass vs Google Cloud IoT Core: What are the differences?

Introduction

In this markdown, we will outline the key differences between AWS Greengrass and Google Cloud IoT Core. Both of these platforms offer IoT (Internet of Things) services, but they have some distinct features that set them apart.

  1. Deployment and Connectivity: AWS Greengrass allows devices to run AWS Lambda functions locally on edge devices, enabling offline data analysis and local computing. On the other hand, Google Cloud IoT Core focuses more on cloud-based computing, relying on the cloud for processing and analysis.

  2. Device Management: AWS Greengrass offers comprehensive device management capabilities such as device provisioning, configuration, and OTA (over-the-air) updates. It provides in-depth control over edge devices. In contrast, Google Cloud IoT Core also provides device management features but is more focused on managing devices at scale, making it suitable for large-scale deployments.

  3. Integration with Platform Services: AWS Greengrass is tightly integrated with the broader AWS ecosystem, providing seamless integration with other AWS services like AWS IoT, AWS Lambda, AWS IoT Analytics, etc. This enables users to leverage the extensive capabilities of AWS for building end-to-end IoT solutions. In comparison, Google Cloud IoT Core is part of the Google Cloud Platform, offering integration with various Google services like Google Cloud Pub/Sub, Google Cloud Functions, and BigQuery.

  4. Data Analytics: With AWS Greengrass, data analysis can be done locally on edge devices using AWS Lambda functions, allowing for real-time decision making. However, in the case of Google Cloud IoT Core, the focus is more on forwarding the device-generated data to Google Cloud Pub/Sub for further processing and analysis using Google Cloud Dataflow, BigQuery, or other platform services.

  5. Protocol Support: AWS Greengrass supports a wide range of protocols, including MQTT, HTTP, and OPC-UA for device connectivity. It provides flexibility in integrating different types of devices. On the other hand, Google Cloud IoT Core primarily supports MQTT and HTTP protocols for device communication.

  6. Pricing Model: AWS Greengrass follows a pay-as-you-go pricing model, where users pay for the resources consumed and the number of Greengrass cores deployed. In contrast, Google Cloud IoT Core follows a pricing model based on the number of registry operations, device state updates, and telemetry events.

In summary, AWS Greengrass emphasizes local computing and device control, seamless integration with the AWS ecosystem, and offers comprehensive device management capabilities. Google Cloud IoT Core, on the other hand, focuses on cloud-based computing, managing devices at scale, and integration with the Google Cloud Platform services for data processing and analysis.

What are some alternatives to AWS Greengrass and Google Cloud IoT Core?
Azure IoT Hub
Use device-to-cloud telemetry data to understand the state of your devices and define message routes to other Azure services without writing any code. In cloud-to-device messages, reliably send commands and notifications to your connected devices and track message delivery with acknowledgement receipts. Device messages are sent in a durable way to accommodate intermittently connected devices.
Mosquitto
It is lightweight and is suitable for use on all devices from low power single board computers to full servers.. The MQTT protocol provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for Internet of Things messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers.
Amazon IoT
AWS IoT is a managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices. AWS IoT can support billions of devices and trillions of messages, and can process and route those messages to AWS endpoints and to other devices reliably and securely. With AWS IoT, your applications can keep track of and communicate with all your devices, all the time, even when they aren’t connected.
Node-RED
It is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.
AWS IoT Device Management
AWS IoT Device Management makes it easy to securely onboard, organize, monitor, and remotely manage IoT devices at scale. IoT Device Management lets you register your devices individually or in bulk, and manage permissions so that devices remain secure. Then, you use the IoT Device Management console to organize your devices into groups, monitor and troubleshoot device functionality, and send remote updates to your devices.
