Things self MQTT migration IoT platform combat
Foreword
With business growth, self MQTT cluster maintenance costs rising, connection stability, keep getting the message latency top business challenges, migration of Things IoT Ali cloud platform is a very wise choice.
Existing business background
Enterprise data interaction based self MQTT cluster as shown below: 
device-side cluster MQTT to publish service data, the service server to the backend process flow; service server issues an instruction to the cluster MQTT, touch reach the device. DETAILED service data is defined as follows:
| Business scene | Theme Topic | Payload packets |
|---|---|---|
| Equipment reports | cdb/data/post | DE02,10,17,011101010,am024,1d478f |
| Server control instructions | cdb/cmd/push | CMD,82923,ad322 |
Infrastructure Solutions
When we migrate from their own MQTT cluster of things to IoT platform, we can use the following technical solutions to achieve rapid migration of low-cost, reducing conversion device side and business systems.
IoT devices on the cloud migration in three steps:
