Azure Logic Apps

 What is Azure Logic Apps?

Azure Logic Apps is a cloud-based platform for creating and running automated workflows that integrate your apps, data, services, and systems. With this platform, you can quickly develop highly scalable integration solutions for your enterprise and business-to-business (B2B) scenarios.

The following list describes just a few example tasks, business processes, and workloads that you can automate using the Logic Apps service:

1. Schedule and send email notifications using Office 365 when a specific event happens, for example, a new file is uploaded.
2. Route and process customer orders across on-premises systems and cloud services.
3. Move uploaded files from an SFTP or FTP server to Azure Storage.
4. Monitor tweets, analyze the sentiment, and create alerts or tasks for items that need review.

How logic apps work

In a logic app, each workflow always starts with a single trigger. A trigger fires when a condition is met, for example, when a specific event happens or when data meets specific criteria. 

Following the trigger, one or more actions run operations that, for example, process, handle, or convert data that travels through the workflow, or that advance the workflow to the next step.

For example, the following workflow starts with a Dynamics trigger that has a built-in condition named When a record is updated. The actions include transforming XML, calling a web app that updates data, evaluating a condition that controls which actions to take, and sending an email notification with the results. When the trigger detects an event that meets the condition, the trigger fires, and the actions in the workflow start to run. Each time the trigger fires, the Logic Apps service creates a workflow instance that runs the actions.

You can visually create workflows using the Logic Apps designer in the Azure portal, Visual Studio Code, or Visual Studio. Each workflow also has an underlying definition that's described using JavaScript Object Notation (JSON). If you prefer, you can edit workflows by changing this JSON definition. For some creation and management tasks, Logic Apps provides Azure PowerShell and Azure CLI command support. 

Why use Logic Apps

The Logic Apps integration platform provides prebuilt Microsoft-managed API connectors and built-in operations so you can connect and integrate apps, data, services, and systems more easily and quickly. You can focus more on designing and implementing your solution's business logic and functionality, not on figuring out how to access your resources.

You usually won't have to write any code. However, if you do need to write code, you can create code snippets using Azure Functions and run that code from your workflow. You can also create code snippets that run in your workflow by using the Inline Code action.
