Azure Functions Reviews & Product Details

1. It makes app creation simpler compared to traditional coding mechanisms.

2. It is fully set up on the cloud, so the impact of hardware failure is negligible.

3. It also supports multiple programming languages. Review collected by and hosted on G2.com.

It always requires a strong, reliable internet connection to access the application. Also, because it’s serverless, debugging can sometimes become complex. Review collected by and hosted on G2.com.

I love Azure Functions. I’ve deployed a series of Python-based function apps—some are event-driven triggers for network operations, and others use dataframes to aggregate data from various sources. I also started using Durable Functions for AI agentic workflows, and the built-in fault tolerance and scalability work amazingly well for us. Using the UI is pretty straight forward, to provision, monitor and deploy . Review collected by and hosted on G2.com.

I don’t think there’s anything I dislike. I’ve never had any issues, as long as the setup is done correctly. Review collected by and hosted on G2.com.

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.

Azure functions are very intuitive to setup from Azure portal or even from visual studio. Sound knowledge of CSX is required for smooth integration. Functions do follow the industry standards for serverless architecture and help to automate lot of redundant tasks. Review collected by and hosted on G2.com.

The portal edit tool is bit weak when compared to a text editor or IDE. It is okay for writing small functions, but anything complex and you need to use an IDE. Review collected by and hosted on G2.com.

They are so easy to use, very powerfull and very easy to manage Review collected by and hosted on G2.com.

Like everything in azure, the worst about them is the price, but it's worth it 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.
