"Azure Lambda: Serverless Computing Power"
4/5
What do you like best about Azure Functions?

Azure Functions offer incredible scalability and flexibility, allowing me to quickly handle varying workloads and demands. The seamless integration with other Azure services enables efficient and streamlined development of complex workflows. The pay-per-use pricing model ensures cost-effectiveness, as I only pay for the resources consumed during function execution. The extensive language support and developer-friendly tools make building and deploying serverless applications on Azure Functions a joy. Review collected by and hosted on G2.com.

What do you dislike about Azure Functions?

While Azure Functions offer numerous benefits, a few aspects could be improved. Firstly, the local development and debugging experience can sometimes be challenging, making identifying and fixing issues harder. Additionally, the cold start latency for functions can be noticeable, leading to potential delays in processing requests. Integration with certain external services can also be complex, requiring additional configuration and setup. Lastly, the pricing model for Azure Functions can be intricate, making it difficult to estimate costs for larger deployments accurately. Review collected by and hosted on G2.com.

"Create Micro Applications/Functions on the go"
5/5
What do you like best about Azure Functions?

We can create small Functions for a quick activity in any programming language we wish to finish minor work. The best feature is that it can be called in by other Functions, your Enterprise Application or via a Logic App Review collected by and hosted on G2.com.

What do you dislike about Azure Functions?

This works on Pay per Use, so every time your function is called, you will be charged for it; this is good when the frequency is not significant, but if the frequency is higher, then Azure Web App Services would be better Review collected by and hosted on G2.com.

"The best serverless solution for triggered functions."
5/5
What do you like best about Azure Functions?

The Azure functions are serverless, and that's the best thing. No need to worry about managing a server or anything like that. If you want to call a function over the cloud, go for it. Like, a cron job, for example. Review collected by and hosted on G2.com.

What do you dislike about Azure Functions?

There are certain things which lack in Azure Functions. Because of their serverless nature, they may take a longer time to start, also known as a cold start in programming. This may cause your business logic dependent upon it to delay and may cause the performance drop. Review collected by and hosted on G2.com.

"Utilize Azure Functions for serverless workloads"
4.5/5
What do you like best about Azure Functions?

I don't need a server to run my application code by using Azure Functions where the infrastructure is maintained by Azure and we focus only on the functionality. Review collected by and hosted on G2.com.

What do you dislike about Azure Functions?

Consumption plan could potentially have a low start latency when the functions are idle, which could impact the app. Review collected by and hosted on G2.com.

What do you like best about Azure Functions?

Azure Functions is a fantastic serverless computing platform by Microsoft to build scalable and efficient cloud-based applications. It enables developers to create microservices, APIs, and triggers, by writing small pieces of code that can be executed quickly and securely without having to worry about infrastructure management.

One of the significant advantages of Azure Functions is its excellent support for multiple programming languages, including .NET, Java, Python, and JavaScript. This feature allows developers to work with languages and frameworks they are most comfortable with and increases the flexibility of the platform.

Another great feature of Azure Functions is its scalability and availability. Since you only pay for the resources you consume, this platform provides a cost-effective way to scale your application based on workload and reduce operating costs. When it comes to availability, Azure Functions has a robust and highly available infrastructure that guarantees a 99.95% SLA.

Azure Functions integrates well with other services and tools in the Azure ecosystem, including Azure Event Grid, Azure Logic Apps, and Azure Blob Storage. This functionality streamlines the development process and enables developers to build complex applications quickly and efficiently.

Finally, thanks to the rich and extensive documentation and community support, Azure Functions is an easy-to-learn platform that helps developers get up and running quickly and easily. Whether you are a seasoned developer or just starting, Azure Functions is an excellent platform to consider, given its flexibility, scalability, and reliability.

Overall, Azure Functions is an exceptional serverless computing platform providing an efficient and cost-effective way to quickly build robust and scalable cloud-based applications. Review collected by and hosted on G2.com.

What do you dislike about Azure Functions?

However, there are some commonly expressed concerns or limitations surrounding the platform, including:

1. Performance: Some users have reported slow performance and stability issues with Azure Functions, especially when working with large-scale applications.

2. Limited Resource Control: While the serverless architecture provides great scalability and flexibility, it also limits the control over the underlying resources, which can be a challenge for more demanding workloads.

3. Cold Start: Azure Functions, like other serverless platforms, can experience "cold start" delays when there is no activity for a while, resulting in slower response times for the first request or trigger.

4. Debugging: Debugging serverless applications can be challenging, as there are no predictable server instances or direct access to the underlying infrastructure.

5. Costs: While the pay-as-you-go model of serverless computing is generally cost-effective, overuse or inefficient architecture can lead to unexpected costs.

Overall, it's essential to weigh the benefits and trade-offs of using Azure Functions when considering it for your application development needs. Review collected by and hosted on G2.com.
