What is AWS Greengrass used for?

AWS IoT Greengrass is an Internet of Things (IoT) open source edge runtime and cloud service that helps you build, deploy, and manage device software. Customers use AWS IoT Greengrass for their IoT applications on millions of devices in homes, factories, vehicles, and businesses.

What is true about AWS Greengrass?

AWS IoT Greengrass is software that extends cloud capabilities to local devices. This enables devices to collect and analyze data closer to the source of information, react autonomously to local events, and communicate securely with each other on local networks.

How does greengrass work?

Greengrass secures data with authentication and authorization at both the network- and device-level. IoT devices in a Greengrass deployment communicate with each other through local networks. A business can filter and transmit only the data it wants to the cloud, which reduces data migration and storage costs.

What is Greengrass deployment?

Deployment is the process to send components and apply the desired component configuration to a destination target device (at the edge), which can be a single Greengrass core device or a group of Greengrass core devices.

What is a greengrass component?

AWS IoT Greengrass components are software modules that you deploy to Greengrass core devices. Components can represent applications, runtime installers, libraries, or any code that you would run on a device. You can define components that depend on other components.

What is greengrass Lambda?

AWS IoT Greengrass provides a containerized Lambda runtime environment for user-defined code that you author in AWS Lambda. Lambda functions that are deployed to an AWS IoT Greengrass core run in the core's local Lambda runtime.

Do I have to use AWS IoT Greengrass OTA updates?

You can use OTA updates to install the latest version of the AWS IoT Greengrass Core software or OTA update agent software on one or more cores. With OTA updates, your core devices don't have to be physically present. We recommend that you use OTA updates when possible.

What are AWS outposts?

An Outpost is a pool of AWS compute and storage capacity deployed at a customer site. AWS operates, monitors, and manages this capacity as part of an AWS Region. You can create subnets on your Outpost and specify them when you create AWS resources such as EC2 instances, EBS volumes, ECS clusters, and RDS instances.

What is Amazon IoT device?

AWS IoT Core is a managed cloud service that lets connected devices easily and securely interact with cloud applications and other devices. AWS IoT Core 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.

What does CLI (); used for?

CLI is a command line program that accepts text input to execute operating system functions. In the 1960s, using only computer terminals, this was the only way to interact with computers. In the 1970s an 1980s, command line input was commonly used by Unix systems and PC systems like MS-DOS and Apple DOS.

How do you remove local components from greengrass?

To remove a component from a device, where the device is no longer a member of the thing group that deploys that component, use the deployment create command of the Greengrass CLI. Specify the component to remove with the --remove argument, and specify the thing group with the --groupId argument.

How do I delete a component in greengrass?

To delete a component, click Greengrass, Components, then Click on the link for the un-desired component (e.g. aws. greengrass. JetsonDLRImageClassification ). Click, Delete version.

What are edge locations used for?

An edge location is where end users access services located at AWS. They are located in most of the major cities around the world and are specifically used by CloudFront (CDN) to distribute content to end user to reduce latency. It is like frontend for the service we access which are located in AWS cloud.

What is greengrass Lambda?

What is Amazon IoT device?

Do I have to use AWS IoT Greengrass OTA updates?

What is the difference between AWS edge locations and local zones?

Mainly edge location is used to host the web content (Statit or Dynamic) it may be in the form of Cache or the uploaded one by a user while local zone is mainly used for infrastructure deployment that places compute, storage, database, and other select AWS services close to large population.

Is edge location and CloudFront same?

CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you're serving with CloudFront, the request is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance.

Is an AWS edge location a data center?

Edge locations are AWS data centers designed to deliver services with the lowest latency possible. Amazon has dozens of these data centers spread across the world. They're closer to users than Regions or Availability Zones, often in major cities, so responses can be fast and snappy.

What is the difference between lambda and Kubernetes?

Lambda invokes a given function in a run environment, which provides a secure and isolated runtime where the function code is run. AWS-managed offerings for Kubernetes provide integrations with managed offerings. Kubernetes itself has a rich partner ecosystem, offering integration with numerous other technologies.

What is Lamda function in AWS?

AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you. These events may include changes in state or an update, such as a user placing an item in a shopping cart on an ecommerce website.

Why are lambdas called lambdas?

Lambda (or \lambda) is the name given to anonymous functions in some languages like Python. These are functions not bound by an explicit identifier. This name is derived from Lambda calculus, a mathematical system to express computation introduced by Dr. Alonzo Church in the 1930s.

What are the three 3 main components of IoT?

The basic three components of IoT includes “Things”, “Internet”, and “Connectivity”. Interoperable connection to local network, cloud or other devices. IoT components are tied together by networks, using various wireless and wireline technologies, standards, and protocols to provide pervasive connectivity.
