Azure Logic Apps Vs Azure Function Apps

Introduction

Azure Logic Apps

• Azure Logic Apps is a cloud-based platform for creating and triggering automated workflows which will be integrated by data, services, systems, and apps.
• In simpler words, using this platform we can quickly develop a highly scalable application with integration solutions for enterprise and business-to-business (B2B) organizations.

Components of Logic App:

• Workflows – Used to define the different types of steps of business process using a graphical user interface present in the portal. There are a series of steps to be followed are visualize, design, build and automate.
• Actions – represents a step in the process of workflow also which is used to invoke a specific operation using an API.
• Triggers – creates an instance for a workflow and initiates a workflow. Triggers will get activated when a set of conditions is satisfied, you can add those conditions in actions to control your workflow.
• Managed Connectors – are used to connect different types of services and resources and also provide some inbuilt set of managed connectors.

Azure Function App

• Azure Function App is a serverless computing service that allows users to build workflows without worrying about the backend infrastructure and web servers.
• Basically, this service works by using event triggers which are used to initiate the workflow.
• Azure Function is a solution for running small pieces of code and functions easily using multiple programming languages including C#, JavaScript, Python, and Typescript.

Differences between Function App and Logic Apps

When to use Azure Logic Apps & Function App?

• Logic Apps are mainly used only when events occur at a lower frequency. It can be the easiest way to work when the user is not good at programming skills.
• It can be mainly used for scenarios like timer-based processing, SAAS event processing, and integration between cloud services.
• Function Apps are mainly used for high-frequency tasks which require a thousand numbers of executions.
• It can be used for scenarios like timer-based processing, and batch and stream data processing.

Conclusion

From this blog, we all will get to understand which is the suitable choice for using the serverless services from the Logic Apps and Function Apps, and both services will follow the same procedures using triggers and following workflows.
