About

AWS IoT Core is the managed message broker and device registry in Amazon Web Services. Devices publish and subscribe over MQTT or MQTT over WebSocket Secure, publish over HTTPS, and LoRaWAN devices join through AWS IoT Core for LoRaWAN. A rules engine runs SQL over the topic stream and hands matching messages to other AWS services. The Device Shadow service keeps a JSON document per thing with desired, reported, and delta state, and AWS IoT Jobs sends remote operations to a set of things.

An operator on Fibric subscribes to the topics you allow, reads shadows and thing attributes, and proposes the desired-state update, the job, or the ticket for your approval.

This is a reference listing. It documents what Fibric would read from AWS IoT Core and what it could propose, based on the vendor's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Messages on the MQTT topics your policy allows, received by a subscribed client or forwarded by a rule action such as SQS, Kinesis Data Streams, or HTTP
  • Device Shadow documents with desired, reported, delta, version, and timestamp through the Device Shadow REST API and the $aws/things/thingName/shadow topics
  • Thing objects, thing attributes, thing groups, and certificates through the AWS IoT control plane API
  • Rules, their SQL statements and actions, and failures delivered to a rule's error action
  • Job executions and their status for each thing a job targets
  • Connect and disconnect lifecycle events, with a persistent session expiry that decides which missed messages are kept

Proposed actions

  • Target capability: propose a desired-state change by updating a named or classic Device Shadow
  • Target capability: propose an AWS IoT Job that sends a job document to a list of things or a thing group
  • Target capability: propose publishing a command message to an application-defined MQTT topic
  • Target capability: propose a rule with a SQL statement, an action, and an error action

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Notice the thing that went silent

    Subscribe to the topics your devices publish on and watch the reported timestamp in each shadow. When a thing misses its interval or a disconnect event fires, propose the ticket with the last message.

    With Sensor Health, Data Freshness

  • Change a setting through the shadow

    When a reported value crosses your limit, propose the desired-state update. The device receives the delta on its topic, applies it, and reports back; you see both the change and the confirmation.

    With Cold Chain Excursion, Setpoint Drift

  • Roll a fix out to a fleet

    Propose an AWS IoT Job with the job document and the thing group it targets. You approve the rollout; Fibric watches each job execution and records the outcome per thing.

Requirements

  • An AWS account with its IoT data endpoint and an IAM principal allowed to subscribe, publish, and read shadows for the named resources
  • An AWS IoT policy on the certificate or identity that lists the topics, things, and shadows it may touch
  • TLS 1.2 or 1.3 to the endpoint; a client on port 443 with X.509 must send the ALPN protocol name
  • Rules created in the same AWS Region as the resource their action writes to
Authentication
X.509 client certificates for MQTT on port 8883, or on 443 with ALPN x-amzn-mqtt-ca; AWS Signature Version 4 for MQTT over WebSocket and HTTPS on port 443; or a custom authorizer. Control plane calls use IAM credentials.

Limits

  • MQTT payloads are capped at 128 Kilobytes; a Device Shadow JSON state document at 8 Kilobytes with a depth of 8
  • Account defaults: 20,000 inbound and 20,000 outbound publish requests per second, 3,000 connect requests per second, 50 subscriptions per connection; some Regions are lower
  • Rules: 1,000 per account, 10 actions per rule, 20,000 evaluations per second; a shadow accepts 20 requests per second per thing
  • Shadow messages can reach a device out of order; the version number is what separates a stale delta from a fresh one

Questions and answers

How does Fibric receive device messages?
Either as an MQTT client that subscribes to the topics your AWS IoT policy allows, or through a rule action that forwards matching messages to a queue, a stream, or an HTTPS endpoint. MQTT supports QoS 0 and 1; HTTPS clients can only publish.
What separates a shadow update from a job?
A shadow holds desired and reported state for one thing, up to 8 Kilobytes, and publishes a delta whenever they differ. A job sends a job document to many things or a thing group and tracks each execution. Fibric proposes both for your approval.
What are the message size and rate limits?
The MQTT payload limit is 128 Kilobytes. Default quotas are 20,000 publish requests per second per account in each direction, 100 per second per connection, and 50 subscriptions per connection. Several quotas are adjustable, and some Regions start lower.
