Serverless is powerful and flexible way of delivering fast and scalable solutions in Azure. Today we will get introduction about Azure Function Apps, one of my favorite services and one of the best serverless services out there.
In this video I will cover basics of Function Apps and show quick demo where I create HTTP service in the portal and BLOB triggered function from Visual Studio Code. All in .NET Core 2.2 version.

Excellent video, but it would be worth mentioning that there are two (quite different) types of Function App Services: Code-based (what you are explaining here brilliantly) and Docker Image based Function App Services. The Docker-based Function Apps are CI/CD integrated via Docker Hub or Azure Container Registry. Nice video, anyhow, I am a subscriber.

@AdamMarczakYT 4 года назад

At the time of recording of that episode docker function images did not exist if I remember correctly. But nonetheless I tried to focus on what functions are and how they work rather than cover all the deployment options :) Thanks for the sub, welcome aboard.

@RSingh- 4 года назад

As always, amazing video Adam! A quick question: How do Azure Functions fare when compared to Azure Databricks in terms of processing performance ? Can Azure Functions be used to replace Azure Databricks if the use case is to do some processing on Python Dataframes (created from data in Azure Data Lake Storage) and then store results in Azure SQL Database?

@AdamMarczakYT 4 года назад

Functions should be used to serverless programming. They are better to process a lot of small requests. Databricks is for one big batch processing or streaming scenarios. Thanks for watching :)

Nice tutorial. Can you explain calling an Azure function with Blob trigger in logic app? Thanks for your effort it really helped me a lot.

@AdamMarczakYT 3 года назад

As the name suggest blob triggered function can only be called (triggered) by a new blob. So you need to create a blob from logic app or change the function. You can also force the trigger check using management API docs.microsoft.com/en-us/rest/api/logic/workflowtriggers/run

Succinct, clear and very insightful video. Would you recommend Azure Function to scrap a .pdf attachment, extract table data, and create rows in Azure Sql Server DB? Which language - Python or .Net?

@AdamMarczakYT 4 года назад

Thanks! :) I'd say it depends, normally I'd go for functions but it depends on size and library that you find. Remember that serverless functions have 1,5GB memory limit (some libraries like to use a lot), otherwise you would need to use functions on app service plan and pay static monthly fee. So if your PDFs are small this would be very nice and very cheap, otherwise nice serverless alternative would be Azure Container Instances (got also a video if you want, feel free to check it out).

@webdeveloperify 4 года назад

One question please. Azure function has a default of 5 minutes timespan for runing any code however we can increase to maximum upto 10 min in consumption plan. If we do not want to have time limit option does "Orchestration framework" in azure function will help to run a single code for about 30 min in consumption plan. Thank you once again for the amazing video.

@AdamMarczakYT 4 года назад

Thnaks :) As to your question. 10 Minutes is a hard limit on consumption plan. You can use premium functions plan but in the end it's minimum 1 server setup (i.e. scales from 1 to N) which allows for always on setting without timeout.

@shivamgupta6020 2 года назад

@adrienducret5338 4 года назад

Hi, Thanks for the video. I had a question. At 11:13 you talked about the storage account. Can you precise the configurations of the storage account we need ( General purpose V1, V2; Blob.., Replication : LRS ,GRS..., acces tier: cool , hot)... Thanks for your help

@AdamMarczakYT 4 года назад

Hey thanks! For the storage account, if you create function from the portal it will automatically create new storage with it. If you want existing here is the reference docs.microsoft.com/en-us/azure/azure-functions/functions-scale#storage-account-requirements but in short you just need to make sure your storage account support tables and queues because they are internally used by function engine. So blob-only storage accounts (including premium storage) and general-purpose storage accounts with zone-redundant storage replication, are not compatible.

@larryfeng8470 4 года назад

Hi Adam, how to choose between Function Apps and Databricks? Both can perform data transformation and be integrated into ADF. Thanks!

@AdamMarczakYT 4 года назад

In ADF function apps pay role of supplementing the features of ADF, usually by calling external services and providing functionalities that ADF doesn't have. They are not designed to be used for ETL in ADF. In general they can be used like that, just it's not ADF development paradigm.

@AdamMarczakYT 4 года назад

Thanks. To get the blob from storage use blob trigger like specified here docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob?tabs=csharp and to save file locally use File System operations. This depends on the language but from function app you have access to wwwroot path so you can just save stuff there. Although this is usually bad design and should be avoided if possible.

You can use app settings to indicate environment stage and simply create IF/ELSE during initialization based on that.

@AdamMarczakYT 4 года назад

Hey Steven, most likely the UI changed. Cloud changes all the time, but they still work just need to setup manually. In general you shouldn't really develop in the portal anyway so it shouldn't be an issue. My hunch is that they removed it as those required additional setup so could be too complicated to be there at glance. You can check supported binding here docs.microsoft.com/en-us/azure/azure-functions/functions-versions#bindings

Hi Adam, What you recommend for a developer to watch video in any particular order? I am a developer new to Azure, to speed up, I want to learn azure in general and as a developer to write program to administrator and use recourses at azure from C#, or Python. I think I would be overwhelmed to learn and practice everything in short time. Another question is we can surely Trigger Function from storage queue. Can we write a trigger based on the table that exists in the storage and that table has a column, for example, "Execute", if it is true then trigger should start the function.

@AdamMarczakYT 3 года назад

For the second question check azure function bindings docs. You can't trigger of table storage entries but you can use it as an input. In general if you put something to a table storage then also output something to the queue so that azure function can trigger of that.

@ishaaq-5563 Месяц назад

Anyone else come across the following issue with Azure Functions > create your azure function locally using the azure extension in VS code. Function app is already created along with corresponding storage account. But when you try deploy the Function to Azure the deployment says successful but no function appears in your Function App on the cloud. The modules i am using in my Python script is just psycopg2.

@AdamMarczakYT 4 года назад

Thanks! Unfortunately blob output doesn't support IAsyncCollectors yet so your best bet is to create dynamic runtime bindings with IBinder class. It's not that complicated to be honest, especially since samples show how to do it with blobs. Here is the doc describing this docs.microsoft.com/en-us/azure/azure-functions/functions-dotnet-class-library#binding-at-runtime

@venkatx5 4 года назад

I thought Azure Functions are Stateless, But you mentioned Storage is used to store state of Azure function. Is it just the Function's deployment/running status(Eg. Enabled/Disabled)? Or the function code can handle session states?

@AdamMarczakYT 4 года назад

You are correct. The function app itself saves state for application runtime information. Like job statuses, trigger executions, etc. Like if you have blob trigger then functions save state whenever blob demo.txt was already processed so it doesn't trigger twice for the same file. But functions itself (the pieces of the code you write) those are stateless in nature.
