Function as a Service (FaaS) providers are cloud computing services that allow developers to execute small units of code, or functions, in response to events without managing the underlying infrastructure. These providers offer a serverless architecture where the scaling, monitoring, and management of infrastructure are handled automatically, allowing developers to focus on writing code. FaaS platforms typically charge based on the number of executions and the duration of the function, making it a cost-efficient option for event-driven applications, microservices, and real-time data processing.

    IronFunctions
    ​IronFunctions is an open source serverless platform, also known as a Functions-as-a-Service (FaaS) platform, that allows developers to write functions in any language and deploy them across various environments, including public, private, and hybrid clouds. It supports AWS Lambda function formats, enabling seamless import and execution of existing Lambda functions. Designed for both developers and operators, IronFunctions simplifies coding by allowing the creation of small, focused functions without the need to manage the underlying infrastructure. Operators benefit from efficient resource utilization, as functions consume resources only during execution, and the platform's scalability is managed by adding more IronFunctions nodes as needed. It is built using Go and leverages container technologies to handle incoming workloads by spinning up new containers, processing the payloads, and returning responses.
