In this Azure tutorial, we will discuss How To Organize Azure Functions. Along with this, we will also discuss a few other topics Azure Function App Multiple Functions, and Azure Function Folder Structure.
How To Organize Azure Functions? There are multiple ways to organize Azure Functions. A few key ways are as below
- Organize Azure Functions Based On Your Business Domain
- Keep the Highly used Functions in their Own Function App
- Make sure to keep the related Functions together in a Function App
- Keep the functions based on their category of usage
- Don’t Deploy different versions of Azure Functions together.
- Group the Azure Functions together based on the Trigger Event Category
Below we will discuss in detail each of the categories mentioned here.

How To Organize Azure Functions
Well, here we will discuss a very important topic. As we know the importance of the Azure Functions. We will have to create many Azure Functions as part of our requirements. But the main thing here is, we should know How to organize the Azure Functions.
Organize Azure Functions Based On Your Business Domain
You should organize your Azure Functions Based on your Business domain requirement. We will get a better understanding if we will take an example. For example, if you will consider a travel agency. They have two departments one is Cab booking and another department is Support and maintenance.
The travel agency is using a set of serverless Azure functions to automate their Cab Booking Process and Another set of Azure Functions to automate their support and maintenance part.
You should keep all the Azure Functions related to Cab booking in the Cab Booking Azure Function App and then you should keep the set of Azure Functions related to the support and maintenance in the Support function App.
Keep the Highly used Functions in their Own Function App
This is another very important strategy that means Always keeping the high-use Azure functions or those Azure functions that usage is more in their own Azure Function Apps. Because if you will keep a few less usage Azure functions with a high-use Azure function then there is a chance that all the functions will scale more CPU usage and memory usage unnecessarily.
This is the reason if you will keep the high usage function in its own Azure Function App then it will only scale the components that need additional resources and memory usage. This is an excellent idea. The only trick here is to identify the highly use Azure Function that you can catch easily.
Another idea is to keep the related Azure Functions together in an Azure Function App. Because keeping some unrelated Azure Functions together in an Azure function App is a very bad idea.
If you will consider the Consumption-based plan, as per the plan there is a very minimal difference between the scenario where seven function apps contain a single function and the function app containing seven functions. The charges you will get are based on the invocations of the functions.
In certain scenarios, there is a chance that both the Azure Functions belong together, But still, considering the performance Perspective, you should keep the functions in separate function apps. This is when you are considering the performance of the Azure Function as the key.
Keep the functions based on their category of usage
Another strategy is As an organization, you will have to work with many Azure Functions and it is quite difficult to find out in case you are looking for any specific one and that one might be very similar to the others. In this type of scenario if you will keep the Azure functions together based on their category of usages then it will be very much easy for you as an organization to pool out in case you need any specific for maybe any enhancements or changes.
Don’t Deploy different versions of Azure Functions together
If you are not very sure about the versions of different Azure functions then don’t keep them all together inside one Azure Function App. In case of any exceptions, or if you want to add any package then it will create a lot of issues in case the versions are different.
The maintenance and patching will be easier in case if you will keep the same versions of Azure functions together inside an Azure Function App.
Well, these are a few key ways to organize the Azure Functions together. This is How To Organize Azure Functions.
Group the Azure Functions together based on the Trigger Event Category
It’s a good idea to keep all the Azure Functions together based on the trigger Event category meaning if you have some HTTP-triggered Azure functions. Then keep that HTTP-triggered Azure Functions in one Azure Function App.
This strategy will help you with easier maintenance. If you want to do any code changes or in case of any DNS update activities as a whole, It will make your job easier in these scenarios.
I personally came across this scenario and this strategy really helps you a lot and makes your task easier.
Note: It is always suggested to keep a few related Azure Functions inside the Azure Function App considering the performance and low-risk factor.
Azure Function App Multiple Functions
You can consider the Azure Function App as a container for one or more Azure Functions. you can host one or more Azure functions inside one Azure Function App.
If you will have different Azure Functions with different languages, you can also keep them inside one Azure Function App.
Keeping multiple Azure Functions together inside one Azure Function App depends on many factors like memory consumption, workloads, etc. For example, if all the Azure functions inside the Azure Function App have almost the same workload and all the Azure Functions are consuming the memory within the maximum limit of memory allocated to that particular Azure Function App in total then you can keep them inside one Azure Function App.
But, say you have multiple Azure Functions inside the Azure Function App, One among them is running with a high workload on it, then, in that case, it is better to separate that Azure Function to a separate Azure Function App and the others you can keep on the first Azure Function App.
There is no specific rule document that you should follow while keeping the Azure Functions in different Azure Function Apps, It’s all about your analysis and your solution architecture and it purely depends on your requirements as well.
