Internet of Things on AWS

  1. 1. IoT on AWS Dean Bryen AWS Solutions Architect @deanbryen dean@amazon.com
  2. 2. What to Expect from the Session • Overview of AWS IoT • Message Broker • Rules Engine • Thing Shadow • Thing Registry and Security • Thing SDK • AWS IoT Hardware Program
  3. 3. Things are Becoming Connected Now Not too long from now Soon After Source: Pretty much everyone
  4. 4. Challenges with Connected Things • Connected does not necessarily mean useful • Noise to Signal • Event Driven Computing • Stream Processing, Big Data and Analytics • SECURITY!
  5. 5. AWS IoT DEVICE SDK Set of client libraries to connect, authenticate and exchange messages MESSAGE BROKER 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 THING SHADOW Persistent thing state during intermittent connections APPLICATIONS AWS IoT API THING REGISTRY Identity and Management of your things
  6. 6. AWS IoT Message Broker MESSAGE BROKER Communicate with devices via MQTT and HTTP AWS IoT API
  7. 7. AWS IoT Message Broker Standard Protocol Support (no lock-in) Millions of devices and apps can connect over MQTT and HTTP 1.1 Long-lived bi-directional communication Clients (Devices and Apps) can receive commands and control signals from the cloud Secure by Default Connect securely via X509 Certs and TLS 1.2 Client Mutual Auth Topic Based Architecture (lights/thing-2/color)
  8. 8. AWS IoT Rules Engine RULES ENGINE Transform messages based on rules and route to AWS Services AWS IoT API
  9. 9. AWS IoT Rules Engine Basics SELECT * FROM ‘things/thing-2/color’ WHERE color = ‘red’ 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 - Context based helper functions - Crypto support - UUID, Timestamp, rand, etc.
  10. 10. 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
  11. 11. AWS IoT Rules Engine RULES ENGINE Transform messages based on rules and route to AWS Services AWS IoT API AWS Services - - - - - 3P Services
  12. 12. AWS IoT Rules Engine 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). Invoke a Lambda function Put object in an S3 bucket Insert, Update, Read from a DynamoDB table Publish to an SNS Topic or Endpoint Publish to a Kinesis stream Actions Amazon Firehose Republish to AWS IoT
  13. 13. AWS IoT Thing Shadow AWS IoT API THING SHADOW Persistent thing state during intermittent connections
  14. 14. AWS IoT Thing Shadow
  15. 15. AWS IoT Shadow Flow Shadow Device SDK 1. Device Publishes Current State 2. Persist JSON Data Store 3. App requests device’s current state 4. App requests change the state 5. Device Shadow sync’s updated state 6. Device Publishes Current State 7. Device Shadow confirms state change
  16. 16. AWS IoT Thing 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
  17. 17. AWS IoT Shadow Topics (MQTT) Thing SDK (C-SDK, JS-SDK) makes it easy for you build shadow functionality into your device so it can automatically synchronize the state with the device. AWS IoT Thing Shadow UPDATE: $aws/things/{thingName}/shadow/update DELTA: $aws/things/{thingName}/shadow/update/delta GET: $aws/things/{thingName}/shadow/get DELETE: $aws/things/{thingName}/shadow/delete Sensor Reported Desired Delta LED1 RED YELLOW LED1 = Yellow TEMP = 60F ACCEL X=1,Y=5,Z=4 X=1,Y=5,Z=4 TEMP 83F 60F
  18. 18. AWS IoT Security and Authorization AWS IoT API AUTHENTICATION Secure with mutual authentication and encryption
  19. 19. One Service, Two Protocols MQTT + Mutual Auth TLS AWS Auth + HTTPS Server Auth TLS + Cert TLS + Cert Client Auth TLS + Cert AWS API Keys Confidentiality TLS TLS Protocol MQTT HTTP Identification AWS ARNs AWS ARNs Authorization AWS Policy AWS Policy NEW
  20. 20. Mutual Auth TLS
  21. 21. Security Secure Communications with Things - Single API call to CreateKeysAndCertificate() - Client Generated CreateCertificateFromCSR(CSR) Fine-grained Authorization for: Thing Management Pub/Sub Data Access AWS Service Access { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": ["iot:Publish"], "Resource": ["arn:aws:iot:us-east- 1:123456972007:topic/foo"] }, { "Effect": "Allow", "Action": ["iot:Subscribe"], "Resource": ["arn:aws:iot:us-east- 1:123456972007:topicfilter/foo/bar/*"] }]}
  22. 22. AWS IoT Thing Registry AWS IoT API THING REGISTRY Identity and Management of your things
  23. 23. Thing Registry • key: value • Firmware version • Serial Numbers • Support and Maintenance • Reference Manual URL • Part # reference • Reference to external support system
  24. 24. AWS IoT – Device Management S3 Holds Versioned Firmware Distributions Organize and secure your firmware binaries in S3 Message Broker notifies groups of the fleet using Topic Patterns Alert the fleet (or part of it) of the update, and send the URL to the S3 download Firmware Update Stored in S3 Publish to groups of devices • Ability to update global or within a Region • Rules Engine keeps state of updates and tracks progress in a DynamoDB Table • Store Version in Registry Entry
  25. 25. Get Started with AWS IoT Thing SDK C-SDK (Ideal for embedded OS) JS-SDK (Ideal for Embedded Linux Platforms) Arduino Library (Arduino Yun) Mobile SDK (Android and iOS)
  26. 26. Launching AWS IoT Hardware Program The AWS IoT Hardware Program helps AWS customers build connected products using any hardware platform. IoT Hardware Partners reduce the time to market and improve customer experiences by providing necessary tools, SDKs and sensors to connect their devices to AWS. The program is designed for partners that provide hardware (semiconductors, connectivity modules, sensors, actuators) to customers and are interested in connecting their hardware platform to AWS.
  27. 27. AWS IoT Launch Partners IoT Systems Integrators IoT Communication IoT Management Platform IoT Analytics PlatformIoT Operating Systems
  28. 28. Official IoT Starter Kits, Powered by AWS
  29. 29. AWS IoT Button AWS IoT Button - WIFI button for AWS IoT - Claim the button in AWS Console - Set up Rules and Actions SELECT * FROM ‘button/press’
  30. 30. Pricing Free Tier - First 250,000 messages are free! Normal Pricing - $5 per Million messages received - $5 per Million messages sent 100 sensors each publish one 400-byte message per minute to AWS IoT. AWS IoT then delivers all of the messages to one other device, and also to DynamoDB. Total cost: This example would incur $21.50 monthly AWS IoT cost for publishing of messages, plus $21.50 AWS IoT cost per month for delivered messages, for a total of $43.00 of AWS IoT
