AWS IoT Conditionals

Conditional Processing or Execution Conditions gives you the power to decide if a particular action on AWS RDS will be executed or not when the workflow is triggered by the incoming event. This is similar to the if-then-else logic applied to the execution of an action based on the attribute from the trigger event of the workflow.

Think of Conditional Processing as equivalent of if-then-else, as decision diamond in the flow chart, or the Conditional Branching in BPEL (Business Process Execution Language).

You can add conditional processing to any action in your workflow and evaluate which actions should be performed in response to a particular trigger event identified by its characteristics or the data attributes. You can apply complex logic using AND, OR and grouping of such conditions. Each of the conditions supports different operators based on the event data type being a string (abc and/or 123), number (123), boolean (true/false) etc. Read here to find more about Conditional Processing.

Example Scenario

We will take a scenario where you are using AWS IoT as the trigger application. There could be multiple application actions invoked upon receiving an AWS IoT trigger. Each of the actions in the flow would apply its own execution condition based on the data attributes of the AWS IoT trigger event. This will allow each of the actions to independently choose to execute based on the defined execution conditions.

In this example, the workflow is triggered when a new event or message received on a particular topic. It has two actions, the first an Outlook action and the second a ServiceNow action.

When using AWS IoT as the trigger application, you need to create attributes while setting up the device. All the attributes on all those attributes you can apply the conditions. Refer this page for setting up the attributes.

In Figure 1 below, Microsoft Outlook will send the composed email only when the maxvalue equals 40.

Similarly in Figure 2 below, in the same workflow, a new ServiceNow action will only be performed if the minvalue equals 80.
