Best On-Premises Function as a Service (FaaS) Providers

​Oracle Cloud Infrastructure (OCI) Functions is a serverless computing service that enables developers to create, run, and scale applications without managing infrastructure. Built on the open source Fn Project, it supports multiple programming languages, including Python, Go, Java, Node.js, and C#, allowing for flexible function development. Developers can deploy code directly, with OCI handling automatic provisioning and scaling of resources. It offers provisioned concurrency to maintain low-latency execution, ensuring functions are ready to accept calls instantly. A catalog of prebuilt functions is available, enabling rapid deployment of common tasks without the need to write code from scratch. Functions are packaged as Docker images, and advanced users can utilize Dockerfiles to customize runtime environments. Integration with Oracle Identity and Access Management provides fine-grained access control, while OCI Vault securely stores sensitive configuration data.

Serverless functions, made simple. OpenFaaS® makes it simple to deploy both functions and existing code to Kubernetes. Avoid lock-in through the use of Docker. Run-on any public or private cloud. Build both microservices & functions in any language. Legacy code and binaries. Auto-scale for demand or to zero when idle. Bring your laptop, your own on-prem hardware, or create a cluster in the cloud. Let Kubernetes do the heavy lifting enabling you to build a scalable, fault-tolerant event-driven serverless platform for your applications. You can try out OpenFaaS in 60 seconds or write and deploy your first Python function in around 10-15 minutes. From there you can take the OpenFaaS workshop, a series of tried-and-tested self-paced labs which teach you everything you need to know about functions, and more. An ecosystem for sharing, reusing, and collaborating on functions. Reduce boilerplate code, and share code in the templates store.
