“We designed the back end to handle traffic spikes by caching AI results and scaling?compute?dynamically. Using Azure Functions (Flex Consumption plan), we ensured back-end processes could handle thousands of simultaneous requests without breaking.”
Josh Wagoner, Developer, Pixel Lab
“This is just the beginning. With Azure, the possibilities are limitless.”
Sunil?Ramakrishnappa, Sr. Director of Engineering, Global?MarTech, Coca-Cola
“We’re?proud to pioneer one of the most advanced AI implementations in the league. This experience welcomes fans who previously?couldn’t?fully engage—and?it’s?built on a foundation that turns our developer wish lists into reality.”
Jared Chavez, Technical and Model Development Lead, PS&E
“There is no?GenAI?without responsible AI.”
Nayanjyoti Paul, Associate Director and Chief Azure Architect for Gen AI, Accenture
Azure Functions is a serverless solution that allows you to write less code, maintain less infrastructure, and save on costs. Instead of worrying about deploying and maintaining servers, the cloud infrastructure provides all the up-to-date resources needed to keep your applications running.
You focus on the code that matters most to you, in the most productive language for you, and Azure Functions handles the rest.
Azure Functions allows you to implement your?system's?logic as event-driven, readily available blocks of code. These code blocks are called "functions."?You?write your function code in your preferred language using your favorite development tools and then deploy your code to the Azure cloud. Functions?provides?native support for developing in C#, Java, JavaScript, PowerShell, Python, plus the ability to use more languages, such as Rust and Go.
Functions provides varying levels of support for languages including C#, JavaScript, F#, Java, and Python. ? See Supported languages in Azure Functions for details.?
Functions apps on the Flex Consumption plan or the App Service plan will run or be available 99.95% of the time. ? See?the complete SLA for Functions.
Functions can run on the Flex Consumption plan, Azure App Service plan, Premium plan, or Azure Container Apps plan. ? See Azure Functions scale and hosting plans for details.
Avoid hard-coding access to other services like Azure Blob storage and Azure Cosmos DB using triggers and bindings. Triggers are what cause a function to run, and bindings are declarations that connect the function to another resource. ? See?triggers and bindings Functions supports?for details.?
Create and test functions on your local machine using your favorite code editor and development tools. Connect local functions to live Azure services and debug them on your local computer using the full Functions runtime. The requirements for developing functions on your local computer depend on the programming languages and tools you prefer. ? See?local development environments?for more.
Running Functions on Container Apps is a good fit for multitype microservices architecture in a centralized environment. This gives you consistent network, observability, and billing configurations.
