Azure Functions Reviews & Product Details

I like best about Azure Functions is how simple it makes coding and deployment, letting me focus on solutions instead of servers. It scales automatically, so I never worry about handling extra demand. The pay as you go model feels efficient and fair, since I only pay for what I use. Overall, it gives me freedom to build quickly without the stress of managing infrastructure. Review collected by and hosted on G2.com.

I dislike about Azure Functions is that debugging can sometimes feel tricky, especially when issues happen in the cloud and aren’t easy to reproduce locally. Cold starts may slow things down when functions aren’t used often, which can affect performance. Review collected by and hosted on G2.com.

What I like best about Azure Functions is its serverless architecture, which allows me to run code without managing infrastructure. It is highly scalable and automatically adjusts based on workload, making it efficient for handling varying data volumes.

The event-driven model is very useful for triggering processes such as data transformations, file processing, and integrations with services like Azure Data Factory and Power BI. It also supports multiple programming languages and integrates well with other Azure services, which improves overall productivity and simplifies development.

Additionally, the cost-effective pay-per-use model ensures that we only pay for actual execution time, making it a practical solution for automation and backend processing tasks. Review collected by and hosted on G2.com.

One of the main drawbacks of Azure Functions is the cold start issue, especially when using the consumption plan, which can cause delays for time-sensitive applications. Debugging and monitoring can also be challenging, particularly for complex workflows or when multiple functions are involved.

Additionally, managing dependencies and configurations across environments can become complicated as the application grows. While it is cost-effective for smaller workloads, costs can increase unexpectedly with high execution frequency.

There are also limitations in execution time and resource constraints, which may not be suitable for long-running or heavy processing tasks. Review collected by and hosted on G2.com.

yes help me a lot when I have to run a function that will help me run a database and build the APIS easier. and implement the database changes more easily to deploy it Review collected by and hosted on G2.com.

Yes, that is not free; however, I am happy with this product, which is one of the products that I like the most. Review collected by and hosted on G2.com.

I like the way environment variables and invocation details are handled, how it’s tied to the storage account, and how easy it is for me to connect through managed identity. Review collected by and hosted on G2.com.

Sometimes it’s very slow—especially when the Azure portal is also running slowly. Review collected by and hosted on G2.com.

I like the ease of usability of Azure Functions. Additionally, I appreciate the support provided. The drag and drop functionality to create workflows and test them out is really helpful. Review collected by and hosted on G2.com.

We haven't fully explored all functionalities yet, but what could be improved is creating a dedicated resource group for learning the functionality of Azure Functions. That would be useful. Review collected by and hosted on G2.com.

Things that I like about the Microsoft Azure are firstly the user friendly interface which is understandable to everyone easily, and it is easy to implement the resources which are easily traceable , like all the insights are shown in a very good way making the users to use it frequently, also the integration to the apps is also easier compared to other cloud platforms.

The only thing that i have dislike on is the customer support, its not that bad but they can improve more in providing fast replies to the tickets that are raised by the customers. Review collected by and hosted on G2.com.

The flexibility it gives to implement event driven code with the great automation and microservice integration tool readily available on Azure portal. Review collected by and hosted on G2.com.

Longer tasks take far longer execution times. Plus it has quite a hassle to debug the code. Review collected by and hosted on G2.com.

We rely on Azure Functions a lot in our day-to-day, especially for async processing, webhooks, and real-time triggers across our hybrid cloud setup. What makes it a strong tool is how easily it connects with the rest of Azure. You can plug it into Event Grid, Service Bus, or Cosmos DB in no time. No need to write a bunch of boilerplate. Just wire it up and go. That kind of integration saves serious time during builds.

Getting started was smooth. We had our first function apps live in production within a couple of days.The triggers and bindings take care of most of the boring setup, so you can focus on writing actual code. It runs smoothly with both Python and .NET. Terraform works well too, letting us keep track of changes and handle rollbacks without headaches. When it comes to features, it covers everything you need HTTP calls, queue processing, timers, storage events. Scaling happens automatically and is pretty reliable. Cold starts used to be rough but have gotten much better lately, even on the cheaper consumption plan. We did run into a surprise with costs once. One of our functions got stuck retrying over and over, which blew up usage. Microsoft support jumped on it quickly, helped us find the misconfiguration, and got it fixed fast with no hassle. We use Azure Functions every single day. It runs background jobs, triggers event flows, and ties together a lot of our backend systems. It’s part of our standard toolkit now.

The main pain point has been cold starts, especially on the Consumption plan when running Python or Node.js for workloads where low latency matters. Review collected by and hosted on G2.com.

For processes that run sporadically, it is excellent because we don't have to keep paying for infrastructure. Review collected by and hosted on G2.com.

The cost is high if the process runs many times in the month. Review collected by and hosted on G2.com.

Easy to integrate with security mechanisms, supports multiple languages with Windows and linux platform type. Review collected by and hosted on G2.com.

They should also include the MAC os as platform, that would open up more doors for Apple developers. Review collected by and hosted on G2.com.
