Internet of Things (IoT) Reference Architecture

to converge internet of thing devices with corporate it solutions, teams require a reference architecture for the internet of things (iot).  the reference architecture must include  devices,  server-side capabilities, and cloud architecture required to interact with and manage the devices.  a reference architecture should provide architects and developers of iot projects with an effective starting point that addresses major iot project and system requirements.

a high-level iot reference architecture may include the following layers (see figure 1):

• external  communications -  web/portal,  dashboard,  apis
• event  processing  and  analytics  (including  data  storage)
• aggregation  /  bus  layer  –  esb  and  message  broker
• device  communications
• devices

cross-­‐cutting  layers  include:

• device and application management
• identity  and  access  management

a more detailed architecture component description  can be found in the iot reference architecture white paper .
