Azure Functions Reviews

Azure Functions provides serverless scaling with easy-to-use triggers.

So far, I haven’t experienced any major drawbacks with Azure Function.

Azure Functions helps automate backend tasks, reduces the need for server management, and scales instantly. It’s been a solid way to save development time while also keeping infrastructure costs down.

They are so easy to use, very powerfull and very easy to manage

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

We had an system with a monolyte architecture, and we need to change that.

I use it for automation tasks, especially for creating time-triggered engine calls.

Sometimes they time out, and then I need to find a way to increase the call time.

I use it to automate scripts that need some compute, and I rely on it instead of running persistent VMs.

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 .

I don’t think there’s anything I dislike. I’ve never had any issues, as long as the setup is done correctly.

I’ve automated many scheduled network operations to track network traffic and online devices, and to build reports for stakeholders. Event-driven triggers also help field engineers initiate service provisioning and validate fibre tests.

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.

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.

Sometimes it’s very slow—especially when the Azure portal is also running slowly.

I’ve created multiple Azure Functions for tasks such as key rotation, certificate rotation, and ETL processes with SQL Server. They’re invoked automatically through triggers whenever specific actions occur.

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.

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.

Solves the problem of managing servers and infrastructure by handling scaling and availability automatically, which saves me time and effort. It also simplifies event-driven tasks, like responding to triggers from data changes or APIs.

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

Yes, that is not free; however, I am happy with this product, which is one of the products that I like the most.

Well, the deployment is easier, and you can use it on prdocution also you can run automatation on to continue running the server.

For processes that run sporadically, it is excellent because we don't have to keep paying for infrastructure.

The cost is high if the process runs many times in the month.

Helped reduce infrastructure costs

Azure Functions' seamless scalability and serverless architecture are outstanding. The integration with various Azure services, coupled with the pay-as-you-go model, provides flexibility and efficiency, enhancing overall application development and deployment.

Azure Functions, while powerful, could improve CI/CD integration for smoother workflows. Documentation clarity needs enhancement. Cost, although reasonable, could be more competitive. Additional features like webhooks for user updates and streamlined setup would enhance user experience.

Azure Functions address scalability challenges by providing a serverless model, optimizing resource usage. This flexibility enhances operational efficiency, reduces costs with a pay-as-you-go model, and streamlines application development, encouraging adaptability and innovation in our business processes.
