Kubernetes-native serverless platform for fast, language-agnostic functions
Fission lets developers deploy functions on Kubernetes with just code, offering automatic scaling, 100 ms cold starts, and support for multiple languages without managing containers or Docker images.
Fission is a Kubernetes‑native serverless framework that lets developers focus on writing code while the platform handles container orchestration, scaling, and routing. By abstracting Docker and Kubernetes details, you can create functions in any supported language—NodeJS, Python, Go, Ruby, PHP, Bash, or any Linux executable—and deploy them with a single CLI command.
Functions are executed from a pool of warm containers, delivering typical cold‑start latencies around 100 ms. Automatic scaling reacts to request volume, adding or removing pods without manual intervention. Because Fission runs on your existing Kubernetes cluster, you can reuse the cluster’s monitoring, logging, and security tooling, and you can also extend the platform with custom environments when a specific runtime is required.
Install Fission via Helm or the provided manifests, then create an environment (e.g., nodejs) and a function using the CLI or UI. The framework handles the underlying pods, networking, and load‑balancing, allowing you to iterate quickly from code to production while keeping operational overhead low.
When teams consider Fission, these hosted platforms usually appear on the same shortlist.
Serverless compute service that runs code in response to events without provisioning or managing servers
Serverless compute service in Azure for running event-driven code without managing infrastructure
Event‑driven serverless compute for running code on demand
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
HTTP API endpoint
Deploy a stateless API function that scales automatically with request traffic, handling spikes without pre‑provisioned pods.
Event‑driven data processing
Trigger functions from message queues or cron schedules to process data pipelines, with automatic scaling and zero‑downtime updates.
Microservice augmentation
Add lightweight serverless sidecars to existing services for tasks like image resizing or auth checks, managed via the same Kubernetes cluster.
Rapid prototyping
Iterate on business logic by pushing code snippets directly, seeing results in ~100 ms cold start without building container images.
No, Fission provides language environments; you only need a Dockerfile when creating a custom environment.
Fission supports any Kubernetes version that is actively maintained; refer to the installation guide for the exact minimum version.
Fission monitors request rates and automatically creates or removes function pods; no manual scaling policies are needed.
Yes, you can create custom environments with your own images to run functions in any runtime.
Fission provides a CLI and integrates with the Fission UI dashboard for visual management.
