What is AWS IoT Greengrass V2 and Why You Should Use It
AWS IoT Greengrass V2 is a service that provides AWS Cloud capabilities across all of your local devices. It enables you to run data processing, machine learning inference, data streaming, and other applications on your edge devices without requiring constant connectivity to the cloud. It also allows you to manage your device fleets at scale with features that control rollout rates, timeouts, and rollbacks.
AWS IoT Greengrass V2 Features
AWS IoT Greengrass V2 introduces the following features that make it easier and more flexible to develop and deploy edge software components:
Open source edge runtime: The edge runtime is now open source and distributed under the Apache 2.0 license and available on GitHub. You can view the AWS IoT Greengrass edge runtime code, which allows you to troubleshoot interactions with your application and helps you build more reliable and performant applications running on AWS IoT Greengrass. You can also customize and extend the AWS IoT Greengrass edge runtime to meet your specific hardware and software needs.
Improved modularity: You can add or remove pre-built software components based on your use cases, and your device CPU and memory resources. For example, you can choose to include only pre-built AWS IoT Greengrass components, such as stream manager, when you need to process data streams with your application. Or, you can include only machine learning components when you want to perform machine learning inference locally on your devices.
New development tools: AWS IoT Greengrass includes a new command line interface (CLI) that enables you to locally develop and debug applications on your device. In addition, the new local debug console helps you visually debug applications on your device. With these new capabilities, you can develop and debug code on a test device before using the cloud to deploy to your production devices. AWS IoT Greengrass also provides the Greengrass Development Kit CLI (GDK CLI), which you can use on your development computer to help you develop and publish custom Greengrass components.
Improved fleet deployment features: AWS IoT Greengrass is now integrated with AWS IoT thing groups. This enables you to organize your devices in groups and manage application deployments across your devices with features that control rollout rates, timeouts, and rollbacks.
AWS IoT Greengrass V2 Benefits
By using AWS IoT Greengrass V2, you can enjoy the following benefits:
Reduced latency: You can run data processing, machine learning inference, data streaming, and other applications on your edge devices without requiring constant connectivity to the cloud. This reduces the latency of your applications and improves the responsiveness of your devices.
Reduced bandwidth costs: You can filter, aggregate, and compress data locally on your edge devices before sending it to the cloud. This reduces the amount of data that you need to transfer over the network and lowers your bandwidth costs.
Increased reliability: You can continue to perform local logic and actions based on LoRaWAN sensor input, even when the cloud connection is intermittent or unavailable. This increases the reliability of your applications and devices and ensures that they can operate in offline or remote environments.
Increased security: You can encrypt and sign data locally on your edge devices before sending it to the cloud. This protects your data from unauthorized access or tampering. You can also use AWS IoT Device Defender to monitor and audit your device configurations and detect anomalies and threats.

The device must have at least 128 MB of RAM, 256 MB of disk space, and a Linux operating system with kernel version 4.9 or later. You can use any device that meets these requirements, such as a Raspberry Pi, an NVIDIA Jetson Nano, or an Amazon EC2 instance.
An IAM role: You need an IAM role that grants permissions to AWS IoT Greengrass V2 to access other AWS services on your behalf. You can use the AWSIoTGreengrassV2FullAccess managed policy to create this role.
A thing group: You need a thing group that contains your edge device as a member. You can use the AWS IoT console or the AWS CLI to create a thing group and register your device.
A deployment configuration: You need a deployment configuration that specifies the software components that you want to run on your edge device. You can use the AWS IoT console or the AWS CLI to create a deployment configuration and assign it to your thing group.
Quick Installation
The quick installation method is the easiest way to download and install AWS IoT Greengrass V2 on your edge device. It uses a single command that downloads and runs an installation script from the internet. The script automatically installs the AWS IoT Greengrass core software, registers your device as a thing in AWS IoT, creates a certificate and a private key for your device, attaches an IAM role alias to your device certificate, and downloads the software components that you specified in your deployment configuration.
To use the quick installation method, follow these steps:
Open a terminal on your edge device and run the following command:
wget -q -O - sudo bash -s -- -i ggc_user_name ggc_group_name region aws_access_key_id aws_secret_access_key thing_group_name iot_role_alias_name component_names...
Replace the italicized parameters with the following values:
ggc_user_name: The name of the user that owns the AWS IoT Greengrass core software on your device. For example, ggc_user.
ggc_group_name: The name of the group that owns the AWS IoT Greengrass core software on your device. For example, ggc_group.
region: The AWS Region where you registered your device as a thing in AWS IoT. For example, us-east-1.
aws_access_key_id: The access key ID of an IAM user that has permissions to create things, certificates, policies, and role aliases in AWS IoT. For example, AKIAIOSFODNN7EXAMPLE.
aws_secret_access_key: The secret access key of the IAM user that has permissions to create things, certificates, policies, and role aliases in AWS IoT. For example, wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY.
thing_group_name: The name of the thing group that contains your device as a member. For example, MyGreengrassGroup.
iot_role_alias_name: The name of the role alias that grants permissions to AWS IoT Greengrass V2 to access other AWS services on your behalf. For example, GreengrassV2TokenExchangeRoleAlias.
component_names...: The names of the software components that you want to run on your device. You can specify one or more component names, separated by spaces. For example, aws.greengrass.HelloWorld aws.greengrass.Nucleus aws.greengrass.StreamManager.
Wait for the command to complete. It might take a few minutes to download and install the AWS IoT Greengrass core software and the software components on your device.
Verify that the AWS IoT Greengrass core software is running on your device by running the following command:
sudo /greengrass/v2/bin/greengrass-cli status
You should see a message that indicates that the AWS IoT Greengrass nucleus component is healthy and active, and the software components that you specified are installed and running.
Manual Installation
The manual installation method gives you more control over the download and installation process of AWS IoT Greengrass V2 on your edge device. It requires you to perform several steps manually, such as downloading the AWS IoT Greengrass core software, creating a device certificate and a private key, attaching a policy and a role alias to your device certificate, and deploying the software components to your device.
