AWS January 2016 Webinar Series - Best Practices for Building IoT Backends with AWS IoT & AWS Lambda


Published on

This webinar will familiarize you with the basics of AWS IoT and AWS Lambda and demonstrate how to build IoT backends using these services. AWS IoT is a managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices. AWS Lambda is a compute service that runs your code in response to triggers and automatically manages the compute resources for you.

We will discuss how you can leverage AWS IoT to receive data and send commands to IoT devices. You will learn how to setup device gateways that trigger AWS Lambda functions to process inbound data from IoT devices. You will also learn how to use Lambda to read and write to Amazon DynamoDB, a fast and flexible NoSQL database service for all applications that need consistent, single-digit millisecond latency at any scale.

Learning Objectives:
Understand key AWS IoT and AWS Lambda and AWS IoT features
Learn how to set up a IoT backend using AWS IoT and AWS Lambda
Explore sample use cases, best practices, and tips on using AWS Lambda with AWS IoT
Who Should Attend:
IoT Developers

AWS January 2016 Webinar Series - Best Practices for Building IoT Backends with AWS IoT & AWS Lambda

  1. 1. © 2015, Amazon Web Services, Inc. or its Affiliates. All rights reserved. Presenter: Vyom Nagrani, Sr. Product Manager, AWS Lambda Q&A Moderator: Ajay Nair, Sr. Product Manager, AWS Lambda Q&A Moderator: Olawale Oladehin, AWS Solutions Architect January 28th, 2015 Essentials: Best Practices for Building IoT Backends with AWS IoT & AWS Lambda
  2. 2. AWS IoT: enables connected devices to easily and securely interact with cloud applications Extract and filter data from your devices and take action with custom rules Securely connect and manage any physical device across multiple networks Create web applications that interact with devices reliably at any time Devices Network Security Data Collection Smarts Connect Billions of Devices Lightweight Communication Protocol X509 Certificates DynamoDB, Kinesis, and S3 Trigger Lambda Functions 1 2 3
  3. 3. Benefits of AWS IoT for building IoT backends Secure by Default Connect securely via X509 Certs and TLS v1.2 Client Mutual Auth Multi-protocol Message Gateway Millions of devices and apps can connect over MQTT or HTTP Elastic Pub Sub Broker Go from 1 to 1-billion long-lived connections with zero provisioning Subscribers Publishers Rules and Actions Match patterns and take actions to send data to other AWS services or republish
  4. 4. AWS Lambda: A compute service that runs your code in response to events Lambda functions: Stateless, trigger-based code execution Triggered by events: • Direct Sync and Async invocations • Put to an Amazon S3 bucket • API Gateway call • And many more … Makes it easy to • Build back-end services that perform at scale • Perform data-driven auditing, analysis, and notification
  5. 5. Continuous ScalingNo Servers to Manage AWS Lambda automatically scales your application by running code in response to each trigger. Your code runs in parallel and processes each trigger individually, scaling precisely with the size of the workload. Subsecond Metering With AWS Lambda, you are charged for every 100ms your code executes and the number of times your code is triggered. You don't pay anything when your code isn't running. AWS Lambda automatically runs your code without requiring you to provision or manage servers. Just write the code and upload it to Lambda. Benefits of AWS Lambda for building mobile backends 1 2 3
  6. 6. DEVICE SDK Set of client libraries to connect, authenticate and exchange messages DEVICE GATEWAY Communicate with devices via MQTT and HTTP AUTHENTICATION Secure with mutual authentication and encryption RULES ENGINE Transform messages based on rules and route to AWS Services AWS Services - - - - - 3P Services SHADOW Persistent thing state during intermittent connections APPLICATIONS AWS IoT API REGISTRY Identity and Management of your things AWS IoT: How it Works
  7. 7. AWS IoT Rules Engine Complex Evaluations: Respond to the fleet, not just a single unit. Dozens of functions() available Multiple / Simultaneous Actions: Sometimes a situation requires you to take many actions Simple & Familiar Syntax - SQL Statement to define topic filter - Optional WHERE clause - Advanced JSON support Functions improve signal : noise - String manipulation (regex support) - Mathematical operations - Crypto support - UUID, Timestamp, rand, etc.
  8. 8. AWS IoT Rules Engine Actions Rules Engine evaluates inbound messages published into AWS IoT, transforms and delivers to the appropriate endpoint based on business rules. External endpoints can be reached via Lambda and Simple Notification Service (SNS). AWS Lambda Amazon S3 Amazon DynamoDB Amazon SNS Amazon Kinesis Actions Amazon Kinesis Firehose AWS IoT
  9. 9. AWS IoT Device Shadow - Simple Yet Powerful { "state" : { “desired" : { "lights": { "color": "RED" }, "engine" : "ON„ }, "reported" : { "lights" : { "color": "GREEN" }, "engine" : "ON„ }, "delta" : { "lights" : { "color": "RED" } }, "version" : 10 } Thing Report its current state to one or multiple shadows Retrieve its desired state from shadow Mobile App Set the desired state of a device Get the last reported state of the device Delete the shadow Shadow Shadow reports delta, desired and reported states along with metadata and version

  15. 15. Reference Architecture: IoT backend using Amazon Kinesis and AWS Lambda
  16. 16. Three Next Steps 1. Connect your IoT device to AWS IoT, or purchase one of the AWS IoT hardware starter kits to get started. With a few clicks in the AWS Management Console, you can create an device policy and rule that enables you to securely and easily connect your device to the cloud and access data, business logic, or functionality from your back-end services. 2. Create and test your first Lambda function. With AWS Lambda, there are no new languages, tools, or frameworks to learn. You can use any third party library, even native ones. And every month, the first 1M invokes are on us! 3. Select Lambda as the rule action for your IoT device … Use the sample code and setup instructions to quickly create your first IoT device backend using AWS IoT and AWS Lambda.
