Components/Anatomy of Logic Apps

Logic Apps comprises of a set of building blocks that work hand in hand for the construction of a process, which would orchestrate integrations between various parts. It offers a graphical path to the users to model their business as a series of steps or workflow. The four major components, which form the blocks of Logic Apps are connectors, triggers, conditions, and actions.

Connectors

Connectors, which are code elements that are bundled together for allowing connectivity to a service, form one of the most basic elements of Logic Apps. Each connector outlines its own API and needs certain data so that it can get configured in order to link to the corresponding service. In case of DropBox connector, a DropBox account is a must for the developer wherein he/she has to use his/her own credentials. 

Triggers

The trigger can be defined an event that does the job of kick-starting the workflow, either by simply starting the job without passing any parameters or attaching some initial message to it. Triggers can be categorized into Manual, scheduled and push triggers.

Manual triggers offer an endpoint (URL) that the users directly can call to start the implementation of the workflow. For eg. Manual requests and webhooks.

Triggers that can execute at regular intervals can be termed as the scheduled ones, wherein the schedule can be pre-defined based on regular execution interval or execution based on the specific point in time. For eg. FTP triggers and recurrence triggers. 

Push triggers contribute to events associated with external systems and are implemented when that event happens. For eg: Dynamics 365 and service bus.

Actions

Every step in a Logic App characterization can be defined as an action that includes triggers, scopes, for-each loops, conditions, do-until loops, calls to native actions and calls to connectors. An action can be appropriately defined as the work that the developer chooses to perform with the received input from the connector. Actions also form the foundation unit for billing in the new Consumption pricing model.

Logic Apps is simple yet very powerful service that permits enterprises and developers in creating workflows and cloud-based integrations with off-the-rack components. The focus behind Logic Apps is yielding maximum result by investing minimum possible effort. These are user-friendly and have fantastic DevOps story to take the application from development to production in simple, reproducible steps with the control of ARM templates.
