The open-source nature of the solution is a major advantage, as IT admins can review code and resolve issues themselves. This provides them with a deeper insight into the service’s functionality, which in turn helps them decide whether to adopt it for their business needs.

Deployment

AWS IoT Greengrass provides companies with the tools to deploy and manage IoT devices that connect locally to the cloud. It permits them to write device logic, execute AWS Lambda functions on those devices for quick responses, engage with others quickly and analyze data locally on-premises in order to save costs associated with sending data up-stream for machine learning inference.

The two primary software packages for AWS IoT Greengrass are AWS Greengrass Core and the AWS IoT Device SDK, which enable teams to create Greengrass Groups that run locally on multiple machines while connecting with the AWS Cloud through MQTT (MQ Telemetry Transport). Each device may use either the AWS Greengrass Core software to implement local Lambda functions and applications, or communicate with the AWS Greengrass Device SDK to run a native C++ application.

By creating a Greengrass Group, a business can establish secure connectivity to the AWS Cloud through MQTT messaging and data routing. Furthermore, Greengrass filters and transmits only relevant data from its IoT devices while saving storage and migration expenses.

During deployment, OpenNebula will connect your hosts to Amazon Web Services Greengrass via KVM virtual machine technology. It also transfers drivers from the host, monitors host performance, and launches a virtual machine running as Greengrass Core with your local core image.

Once the VM has booted and been configured as Greengrass Core, it will be ready to use. Be sure to consult the logs in /greengrass/v2/logs for errors or failures during deployments.

Deployment times depend on factors such as host CPU performance, availability of hosts to support Greengrass, and AWS API latencies. For instance, a single physical host with 1 GHz of computational resources and 596 MiB main memory deployed to 15 locations with working Lambda function took 23 minutes and 27 seconds from booting up its Greengrass VM until it returned first measurements to AWS IoT Greengrass.

AWS Greengrass is ideal for devices that need to operate independently from the AWS Cloud, such as autonomous cars and precision farming. It also helps these devices remain operational even without consistent network access. These types of devices can be managed using Greengrass Groups with the capability of syncing data later when internet access becomes available.
