Logic APP vs Function APP

Question

Logic APP vs Function APP, which one is cheaper in general ?

Answer 1

Hi @sakuraime

The logic app is billed for runs the triggers, action, and connector executions whereas the Azure Functions consumption plan is billed based on per-second resource consumption and executions. The pricing will be varied according to the business logic/workflow

I will suggest using the pricing calculator to compare what would be cheaper between the two for your business. But if you have high resource utilization then the function will be cheaper than a logic app.

In azure function consumption plan pricing includes a monthly free grant (*Free grants apply to paid, consumption subscriptions only.) In that scenario, you can leverage function rather than the logic app if it is under the free limit.

I will also suggest reviewing the serverless comparison.

Function App Pricing: https://azure.microsoft.com/en-us/pricing/details/functions/

Azure logic app Pricing

Azure Functions

Consumption plan pricing includes a monthly free grant of 1 million requests and 400,000 GB-s of resource consumption per month.

Azure Function App pricing

Note: Azure Functions can also run under App Service Plan – hence a different pricing model.

In case you leverage the integration account with your Logic Apps than you should be aware of additional costs.
