Azure Functions : User Review **Rating:** 5.0/5.0 stars **Reviewed by:** satyansh s. | Software Development Consultant, Enterprise (> 1000 emp.) **Reviewed Date:** November 28, 2020 **What do you like best about Azure Functions?** I have been using Azure Function for quite some time now. I best part about this being the server-less features and the consumption type pricing plan. Like you need to pay for what CPU time one has consumed. Using Azure Functions helps a lot where You need quick setups and POCs to be made for the client. for e.g. you need to create a CURD operation web service for updating a azure SQL database or a Azure table and alternatively we can create a function app to do the same task. **What do you dislike about Azure Functions?** There is nothing much to dislike but yes one point I would like to raise is that for some of my function app the server when kept long time in idle state takes too long to respond back for the first call. This has been a pain point for systems where we need quick response back from the back end server else the timeout error may be thrown. **What problems is Azure Functions solving and how is that benefiting you?** I have been using Azure Function Apps for tasks like image processing, processing orders, file maintenance, updating Azure SQL Databases and to run scheduled tasks. ### 24. Serverless with Azure **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Architecture & Planning | Enterprise (> 1000 emp.) **Reviewed Date:** November 23, 2021 **What do you like best about Azure Functions?** Speed, maintainability, setup and ease of use **What do you dislike about Azure Functions?** NFR could have been better and having a timeout of 30 could have been customized. Functions should be ideally like a "nano" service **What problems is Azure Functions solving and how is that benefiting you?** Stateless architecture and moving away from the dependency of having code in databases as in legacy ### 25. Azure functions are great for stateless codes with unpredictable usage **Rating:** 5.0/5.0 stars **Reviewed by:** Paul B. | Principal Developer, Mid-Market (51-1000 emp.) **Reviewed Date:** November 17, 2020 **What do you like best about Azure Functions?** * Easy scaling * The Tooling is built directly into a VS Code plugin to very easily create, test, and ultimately deploy your function * Inexpensive * Very fast deployment * Easy to use with custom domains and SSL * Can run as a normal server application if you need to migrate later * Very easy to connect it to other services, like Azure's Queue service, or an HTTP response, or a database **What do you dislike about Azure Functions?** The documentation for durable functions could be better. It's not really clear how "durable" the functions are allowed to be. Otherwise, it's pretty solid. These are better than AWS lambda functions for sure. If I really had to take it to the next level, since Microsoft owns both Azure and Github I would want to see a native integration with Github Actions to make continuous deployment easy to set up. It's not really holding things back though. **Recommendations to others considering Azure Functions:** Just give it a try. It's very easy to get started, especially if you are already using Microsoft Visual Studios Code as your editor. There is a plugin from Microsoft to create and manage your azure function and you can almost everything you will generally need from right in there. The tutorials are also pretty solid, making and deploying an actual Azure function in a temporary test environment. It's a pretty good setup. **What problems is Azure Functions solving and how is that benefiting you?** We were able to build several applications that either run extremely infrequently, or have high but unstable usage that we could put the output into a queue for later usage by a single, small, stateful server. Very inexpensive applications, very reliable and scalable with usage. ### 26.

Direct deployment using publish profile and directly from visual studio makes it easy for testing. Remote debugging enables Devs to debug the code after deployment. **What do you dislike about Azure Functions?** Consumption Plan is enough most of the times. But there is no real meaning in option it as the service goes to sleep after some time of in activity. This leaves user to choose an App service plan which requires some more bucks. **Recommendations to others considering Azure Functions:** It is best option if manupulation of data is required and some complex logic needs to be executed. If the logic is simple and doesnt have much complications , its better to go for Azure Logic apps **What problems is Azure Functions solving and how is that benefiting you?** All the custom manupulation of data , calling APIs , leveraging many packages available in Nuget and hosting it in App services. Possibilities are so many. ### 30.

As you can read this one the best cloud benefits, deploy your C#, javascript or python bunch of code without any server configuration. you only need to do three or less click into your function app and create a new function. Exec these functions it is a piece of cake, you can trigger that with http request as GET, POST, PUT, and DELETE, also, you can handle it with other cloud events as for example, modifying a NoSQL, inserting a message in a Queue Storage, adding blobs in our storage account and more.. Also you can schedule the execution of your azure function, using azure gridevents you can easily start your career with IoT, it means that azure function could be your bridge between real-world and cloud components. It's a good chose for your backend trigger, start with our serverless fun MS has really good videos in youtube to start your learning journey. **What do you dislike about Azure Functions?** Over 4 or 5 years of its first release we don't have an official guide implementation with batch accounts, sometimes you have to jump to this solution because the batch process is not so good. **Recommendations to others considering Azure Functions:** You just need to know your .net framework or javascript taste! **What problems is Azure Functions solving and how is that benefiting you?** The service implementation is the keywords, we integrate with send grind to notify our client some new version of files in our blob storage, we integrate that with this native trigger and realtime emails are inboxing thanks to our azure functions. ### 34.

A serverless computing **Rating:** 4.5/5.0 stars **Reviewed by:** Aleksander K. | System & Software Architect, Small-Business (50 or fewer emp.) **Reviewed Date:** November 13, 2019 **What do you like best about Azure Functions?** It is pretty easy to setup the basic function that’s responses business needs. A lot of supported languages. **What do you dislike about Azure Functions?** To debug locally it can be a little difficult if using some specific API or protecting the access to the function. **Recommendations to others considering Azure Functions:** It is a simple serverless computing. Can be set up directly in portal. **What problems is Azure Functions solving and how is that benefiting you?** With Azure Function I created a automatic task that opens the access for the platform from given IP for authorized user and therefore no need for static IP address and the manual declaration of IP on the firewall. ### 36. Realy useful to code in a scalable serverless way **Rating:** 5.0/5.0 stars **Reviewed by:** Vincenzo C. | Gerente de operaciones, Internet, Enterprise (> 1000 emp.) **Reviewed Date:** September 20, 2019 **What do you like best about Azure Functions?** I like that it is scalable, easy to deploy and to debug. From Visual Studio or Visual Studio Code you can make excelent event handled programs.Its is cheap and supports a lot of languages like Node JS, C# even in Net Core or Net Framework and Python. Also, if in any time you don´t want to use Azure, you can use your code locally in your PC. **What do you dislike about Azure Functions?** That you cant see the code from the Azure Portal. And also, I don't like that is a little tricky to see the logs. I also don't like that the first call to the function may have a timeout because it is "cold" if you don't use it for a while, but later it is "hot" and runs very fast. If you know that it is going to make a timeout, you can use "warmers" to solve this problem or call a function to do this walkaround in a easy way. **Recommendations to others considering Azure Functions:** I recommend it because is really cheap, you can debug in a very easy way. It is really fast to start from a hello world sample. **What problems is Azure Functions solving and how is that benefiting you?** I am making good API's Restfull in C# and in Python. It is very cheap because you pay per use. It is not virtualized code, it is serverless code, so it is scalable. You only have to manage the code and leave the security and infraestructure work and administration to Microsoft Azure. ### 37. The best way to do cloud only Office 365 scripts **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Non-Profit Organization Management | Small-Business (50 or fewer emp.) **Reviewed Date:** August 27, 2019 **What do you like best about Azure Functions?** One of the main features of Azure Function Apps I love is the option to use your existing PowerShell commands to update users.

Visual Studio sometimes freeze up and take incorrect account to connect to Azure. **What problems is Azure Functions solving and how is that benefiting you?** Automation, CRM Dynamics connector, Batch Jobs, Storage Queues and Blob storage. ### 44. Ridiculously scalable micro-processing power **Rating:** 5.0/5.0 stars **Reviewed by:** Diego V. | Senior Software Developer & Team Lead, Enterprise (> 1000 emp.) **Reviewed Date:** April 18, 2018 **What do you like best about Azure Functions?** It is insane how easy it is to start developing in Azure functions, and how amazing the payoff is. If coupled correctly with any of the Azure BUS or queue services, you don't even have to worry about developing usually annoying behavior like concurrency or multithreading - Azure functions handles huge degrees of parallelism. **What do you dislike about Azure Functions?** The learning curve is a bit steep - but Microsoft has also started to let their documentation be crowdsourced, which has greatly improved the way learning any Microsoft specific tools is. **Recommendations to others considering Azure Functions:** Ensure you are using proper configuration settings utilizing the portal application settings on overrides for functions - this allows for easier deployments. **What problems is Azure Functions solving and how is that benefiting you?** High availability and high degrees of parallelism are required for some of our clients' huge volume - this was leveraged entirely by uploading information into Azure queues and working together with Azure functions to process it. This is specially important for us as we do not have to worry about peak times, since Azure allows automatic growth or scheduled growth if you already know the times in which you are expecting exceeding volume. ### 45.
