Bridge emqx cloud data to AWS IOT through the public network

In the IOT business scenario , It often involves real-time extraction of data generated by massive IOT devices 、 Filter 、 Spin off 、 Conversion, etc .EMQ Launched fully managed cloud native MQTT Message service EMQX Cloud Provides high-performance built-in data integration functions , It can help users to implement various cloud services （ Such as Kafka、MongoDB、AWS RDS、AWS DocumentDB、 AWS IoT etc. ） The connection of , Transfer the Internet of things data to various third-party databases as required 、 Message queue 、 In data system , So as to simplify the application development of the Internet of things , Accelerate business delivery .

This article will show you how to use EMQX Cloud The data integration function bridges data to through the public network AWS IoT, With the help of AWS IoT Easy to use AWS Lambda、Amazon Kinesis、Amazon S3、Amazon Machine Learning、Amazon DynamoDB、Amazon CloudWatch、AWS CloudTrail And built in Kibana Integrated Amazon Elasticsearch Service etc. AWS Service building IoT Applications . There is no need to manage any infrastructure , The collection of data generated by interconnected devices can be realized 、 Processing and analysis .

AWS IoT brief introduction

What is? AWS IoT

Amazon IoT Core It is a hosted cloud platform , Let connected devices easily and securely interact with cloud applications and other devices .Amazon IoT It can support billions of devices and trillions of messages , It can process these messages and route them to Amazon cloud technology terminal nodes and other devices safely and reliably . With the help of Amazon IoT, Your application can track and communicate with all your devices at any time , Even if these devices are not connected .

AWS IoT

AWS IoT Advantages of the platform

（1） Extensive and in-depth ：AWS Have extensive and in-depth... From the edge to the cloud IoT service , Provide local data collection and analysis capabilities as well as the cloud for IoT Designed data management and rich analysis integration services .

（2） Multi tier security ： Including preventive security mechanisms （ Such as device data encryption and access control ）、 Continuously monitor and audit security configuration, etc .

（3） Excellent AI Integrate ：AWS take AI and IoT Bind together , Make the device more intelligent . Support multiple machine learning frameworks .

（4） Large scale validation ：AWS IoT Built on extensibility 、 Secure and proven cloud infrastructure , Scalable to billions of different devices and trillions of messages .

Use EMQX Cloud Bridge data to AWS IoT

Opening NAT gateway

stay EMQX Cloud Deployment details page , Open value-added services —- NAT gateway , It is convenient for the public network to access AWS IoT.

To configure AWS IoT

Create transaction

Get into AWS IoT Control panel , Find Management - Business , Click Create transaction , You can create one called emqx The business of .

AWS IoT Create transaction

Create and download certificates

After the transaction is created , You can create a certificate directly .

AWS IoT Create and download certificates

After the certificate is created , You need to download the certificate on this page , Used for two-way authentication when connecting devices .

AWS IoT Download the certificate

Create a policy and associate it with a certificate

Find security - Strategy , Create a emqx-bridge The strategy of , Writing strategy , The configuration is as follows .

Create a strategy

To configure EMQX Cloud Data integration

Get into EMQX Cloud Deployment page for , Click data integration - MQTT Bridge.

To configure EMQX Cloud Data integration

Fill in the resources page AWS IoT Resource details for .

Fill in AWS IoT Resource details for

After confirming that resources are available , Configure rules , Filter and process data .

Rule configuration

After configuring the rules , Response actions need to be configured , That is, bridging data to AWS IoT.

Configure response actions

When you are finished creating resources - Add rules - After adding actions , Relevant information can be viewed on the details page .

Check the details

View created rules , Click monitor , It can be seen that the monitoring times of successful bridging are 0, The initialization state .

Check the number of successful bridge monitoring

Test verification

Use Python SDK Connect to EMQX Cloud Deploy , To the subject emqx/bridge Send a message .

To the subject emqx bridge Send a message

Use MQTTX Connect to AWS IoT, subscribe emqx/bridge, Can receive from EMQX Cloud Deployed messages .

Use MQTTX Connect to AWS IoT

Use MQTTX Connect to AWS IoT1

stay EMQX Cloud console View rule monitoring , You can check bridging data to AWS IoT Successful or not .
