How big a single Azure Function can be?

Question

My Azure Function will require resources to run properly (ranging from 5 to 30 Mb). I'm thinking of putting them on the Blob Storage and loading from the Storage each time function runs, but since it will be quite often (a couple times per day) I'm thinking of simply putting them as resources in the function project.

The question is, how much space can I allocate for the function itself? How big (in terms of disk space) a Azure Function can be?

Answer 1

It depends on which host plan your Function app is on.

For dedicate App service plan(Pricing tier Basic, Standard and so on), we can see the size of disk storage allocated for this plan. Just like @Slava Utesinov has mentioned, we can also check it from Platform features -> App Service plan -> File system storage as well.

For Consumption plan, File system storage shows 0KB usage among 1GB available. Because Function apps on Consumption plan are stored in Storage File Share, which is specified by WEBSITE_CONTENTAZUREFILECONNECTIONSTRING and WEBSITE_CONTENTSHARE Application settings on Azure portal, check doc. As for space, max size of a File share is 5TB, see doc.
