Focus on Code, Not Plumbing
Fission lets developers run code functions easily, while automating the menial work of configuring Kubernetes micro-services concepts behind the scenes.
Just write your code functions and Fission will make it run on Kubernetes.
Portable: Run your Lambda-like service, anywhere
Fission is open source under the Apache license.
Fission works on a Kubernetes cluster anywhere: on your laptop, in any public cloud, or in a private data-center.
Write your application with the flexibility of deploying it anywhere.
Extensible and Customizable
Fission is extensible to any programming language (Python, NodeJS, Go, C#, PHP are supported today).
It abstracts away containers by default, but you can build your own containers if you need to.
Build Serverless API Backends
Create API backends for web and mobile apps without managing servers. Just write functions, and map them to HTTP routes. Fission takes care of the rest: deployment, routing, scalability, availability. Use Kubernetes’ service discovery and networking to interoperate with other services, like Redis, Postgres, Etcd etc.
Easily Implement Webhooks
Webhooks are a popular way to integrate with third-party services. Slack provides webhooks that are triggered by certain words or messages; Github provides webhooks triggered by events in Git repositories. Fission is a great place to implement webhooks: just write the code, map it to a URL, and point the webhook at that URL.
Write Kubernetes Event Handlers
By subscribing to Kubernetes watches, you can write custom automation for your Kubernetes infrastructure. Fission’s integration with Kubernetes watches allows you to monitor resources such as Pods and Services, and execute arbitrary functions when the watched set of resources change.
New in Fission: Live-Reload, Record-Replay, Automated Canary Deployments, Prometheus integration
We’re excited to launch a set of new features for Fission, designed to help you improve the quality and reliability of your serverless applications on Kubernetes.READ MORE
Live-Reload in Fission: Instant feedback on your Serverless Functions
Fission comes built-in with live-reload, a feature that drops the time from code to running tests to a few seconds. Fission is the first open source serverless function framework to do this.READ MORE
