Intro to Azure Functions - What they are and how to create and deploy them

[@kameronfreitag4118]

Microsoft needs to pay you for this. You've made Azure accessible to the layman with clear cut, concise explanations that leave no detail behind. Thank you so much for this!

[@IAmTimCorey]

I appreciate the kind words. While Microsoft does not pay me, they are very generous with their own training and access to their engineers. I'm happy to be able to make the product easier to use and more accessible. The product is great and the pricing is extremely generous.

[@farsidesc4044]

I got into Azure Functions just a few weeks ago. They are INCREDIBLE and super low cost (mostly no cost). I’m not joking when I say, integrating Functions into our workflows has revolutionized our work environment. I say all that to say this: watch this video! Learning it by myself was not pleasant whatsoever!

[@IAmTimCorey]

Thank you! I agree that Azure Functions are awesome. I'll be doing a lot more videos featuring them (including a course or two).

[@oldfootage]

I love Microsoft backend technology. But there is a big sign on the wall that says: tiny guys beat it, get lost. Functions are useless without a db. I don't know if my project will get off the ground. From the get-go I have a $5/month charge for an SQL db. Compare this to a firebase db. $0/month from the get-go. If my project starts to gain customers I can transition over to use the much better MS SQL. I have grown to hate No-SQL. I did not know about the azure pricing calculator before I watched this video. Thanx Tim for showing me that this is not the option for me to go just yet.

[@stylem8132]

Thanks for the great explanation! I have a question that I think would benefit others too. Let's say that I want to create a simple website for a barbershop that allows users to book appointments. Since it's a small business, in order to make hosting completely free, I thought I should make a serverless application using Azure Functions (instead of a web api that would require hosting), firebase authentication and cloud firestore for a DB. After that I would host the website (simple html and css) in Azure Static Web Apps. Do you think this way is viable in terms of security and overall effectiveness? Or should Azure functions be used only for computer to computer scenarios and avoid communicating with the user?

[@IAmTimCorey]

You can definitely use Azure for B2C interactions. For example, the suggestion site ( suggestions.iamtimcorey.com ) is hosted on an Azure Web App with MongoDB in Atlas and has customer interactions. My main website ( www.iamtimcorey.com ) is hosted on Azure Static Web Apps and it is what handles most of my income. I go to Azure when I want reliability, features, and scalability.

I have been following your content for years and you always engage on a level that makes the content easy to digest. I am currently looking for ideas to trigger an azure synapse pipeline after a file is dropped into an azure storage account file-share. I feel that azure functions might be a suitable candidate to implement this. Azure synapse pipelines don't natively support this at the moment. Microsoft do offer a custom events trigger extension capability. However, so far I have found very little evidence demonstrating how to leverage this capability to trigger my synapse pipeline. Any assistance with approaches to solving this would be greatlyt appreciated. Thanks.

[@BernhardHofmann]

I just noticed in the pricing calculator that the million calls per month is only free if the execution time is less than 3.2 seconds. If it's slower than that, firstly what the heck are you doing, and secondly, you will be paying for that function. It's still insanely cheap, but is good to be aware of.

[@IAmTimCorey]

I think that is a newer edition. So I looked into it a bit more. You get 400,000 GB of transactions. The smallest amount of memory your app can use is 128MB (they round to each 128MB). So, if you wanted the full 1 million transactions for free, each would need to be 3.125 seconds long or less. If you wanted half a million transactions, they could run for 6.25 seconds each. In theory, you could do one transaction a month that would run for 833 minutes (there is a cap of 5 minutes per call for standard functions though). So don't worry if a function runs over 3 seconds long unless you are pushing the edges of that 1 million calls a month number. As for what a function could possibly be doing for 3 seconds, that is a good question. It should typically not run that long unless you are asking it to do too much (less a function and more of a batch job).

I am trying to create a web API built from azure functions and i want it to an able to read/write from a database. I remember in your web api videos you saying that you should have database interaction occur in a class library and then the API calls on that if it needs to communicate to the database. While i understand how that works with traditional api approach, how would it be setup using azure functions? Do you just disclude using a class library for database interaction when using azure functions? I remember in this video you gave an example of accessing a database inside an azure function so I'm a bit confused on the common/best practice for database interaction when using azure function.

[@IAmTimCorey]

Yep, you can use a class library with Azure Functions. The trick, though, is to be sure you aren't violating the spirit of a function. If you are trying to create a full API, use ASP.NET Core API.

[@brianpk7206]

@@IAmTimCorey what qualifies as a "full api"? I was going to go the azure function route because the serverless architecture is very appealing since you don't need to manage a server and it's basically free. I would hate to go the traditional approach for web api because you have to own a server and pay for it.

[@hqcart1]

Hello Tim, i have a question about cold start vs hot start, you mentioned here it took around 300ms to start the function + additional execution time, does this mean that hot needs 0ms to start?

[@IAmTimCorey]

Hot start basically means that one function is constantly running. You pay for that, but that way you are always ahead of the load requirements. When you start using one function, a second is spooled up to be ready for load increase and so on. So you avoid the startup time because the function is already started.

[@cnikolov]

I will try azure functions to handle my jwt authorizations. I've seen somewhere in the documentations that you can also limit the usage of the functions so you dont get overly billed. I have a general question when do you use durable function compare to just normal functions? My first thought is when you need to chain functions or perhaps there is other reasons to go for durable? Also what is the process of consideration when you considering the right storage for your application? e.g. cosmos vs sql server. (thanks for pressing on the fact that sql server isn't expensive).

[@IAmTimCorey]

Correct. Durable functions are for chaining them together. As for getting a big bill with functions, that's almost impossible. You get a million calls per month for free. Just make sure it is a short-running function. As for determining the type of database for your application, that's a tricky one. It all depends on your specific data needs.

[@cnikolov]

@@IAmTimCorey last question which I understand is outside of the scope, If you have a .net core web api, you would have various http endpoints decorated with authorise or some other filter logic, how do you do the same without repeating yourself in azure functions let's say you want only users with jwt token that is valid to hit your lambda otherwise throw 401

Hi Tim. How do I register on your site? I am trying to buy your courses but I cannot seem to find your Register Account page and it takes me straight to log in page. And also, your site is not sending me any emails. Is your site still functional? Thanks

You don't register on my site. You just purchase a course. Go to the course you want and hit the buy button. It will ask you for your email address. That email address is what will be used to create an account for you, so use the same one each time. As for the site not sending you emails, I'm not sure what you mean. It isn't designed to send you emails. If you think you are missing something, you can always email [e-mail]
