Developer ExperienceĬode being triggered by an event, whereas Logic Apps is a In the following paragraphs, we will address them. The differences between Logic Apps and Azure Functions range from developer experience to deployments. Also, when you should use Logic Apps or Azure Functions. Now we will compare Logic Apps and Azure Functions, how both can work together. In the previous paragraphs, we explained both Logic Apps and Azure Functions. Below you see a diagram of the components of Azure Functions.įor more information about Azure Functions read the Leveraging Functions on the Azure Platform blog post. Furthermore, Functions leverage a declarative binding and trigger mechanism, which works with several Azure services like Storage, Cosmos DB, and the Service Bus.

The WebJobs SDK runtime, a framework that simplifies the task of writing background processing code that runs in Microsoft Azure, is the foundation of Azure Functions. They are typically designed to serve a single purpose and respond to events in connected services. Although an Azure Function can contain quite a bit of code. Followed by scripting languages, Bash, and PowerShell – and support for Command Line through a CMD or BAT file. You can build the Azure Function in various languages like Node.js, C#, F#, Python, PHP, and even Java.
Logic Apps RP – Reads the workflow definition and breaks down into a composition of tasks with dependencies.The Logic App service runs as said earlier on a set of infrastructure, and it consists of several components. Furthermore, you get billed by some trigger/actions that execute, and scaling done for you – if the number of requests increases, so will the Logic App instances until certain boundaries are reached (see Logic App Limitations). By provisioning a Logic App, you leverage a bit of that infrastructure (indirectly via the Logic App Service) once you define a workflow and the flow gets triggered. For instance, you can trigger a workflow by sending an HTTP request or schedule a workflow every hour to retrieve data from a public website.Ī Logic App runs on the infrastructure of an Azure region (VM’s in a data center), not visible to you as it is abstracted away. A trigger can instantiate a workflow, which can consist of one or many activities (actions). The Logic App is a logical container for one workflow you can define using triggers and actions. You can run a business workflow in Azure using the Logic App service.

In this blog post, we will briefly discuss both services before showing how to use both in a cloud-native integration scenario, comparing Logic Apps and Azure Functions, and when to use either one of them. However, there are differences and depending on your requirements, you can either use Logic Apps, or Azure Functions, or both. You can leverage both Logic Apps and Azure Functions through a consumption plan. If you look at one of the diagrams Microsoft shows in their presentations, you will notice both Logic App and Azure Functions are a part of the Azure platform. In the blog post, " Serverless Computing: Why Should I Consider Using It?," serverless is very well-explained and both Logic Apps and Azure Functions are platform services, and you could even consider them serverless – no infrastructure to manage (done for you by Microsoft), auto-scaling, and billing based on execution or action. Both these services have unique requirements, therefore, comparing Logic Apps and Azure Functions is important. The word "Serverless" is popping up in various articles and blogs on platform services like Logic Apps and Azure Functions.
