Fission is open source under the Apache
License. It works on a Kubernetes cluster anywhere: in your private data
center, in a public cloud, or on your laptop.
Fission maintains a configurable pool of
containers so your functions have very low cold-start latencies,
DECLARATIVE APPLICATION SPECIFICATIONS
Declarative specifications give the developer
the capability to define a function once and then deploy it anywhere.
Fission resources (functions, triggers etc.) can be checked into source
control, and the application can be recreated from them. This helps
reduce the difficulties involved with managing a function base of
serverless code across multiple endpoints.
ADMINISTRATION & OPERATIONAL SIMPLICITY
Fission aims for operational simplicity by
incorporating logs directly into the CLI, via integration with Fluentd.
It also integrates with Prometheus for metrics tracking and dashboard
ISTIO SERVICE-MESH INTEGRATION
Fission integrates with Istio, which is an
open platform to connect, manage and secure micro-services. With Istio,
users also get the ability to monitor function usage and trace request
latency through dashboards.
WIDE LANGUAGE SUPPORT
Fission is extensible to any programming
language of your choice. Python, NodeJS, Go, C#, PHP are supported
today, but you can build your own custom containers if you need
Fission provides autoscaling for functions
based on CPU usage. In future, custom metrics will be also supported for
scaling functions. You can set the initial and maximum CPU for a
function and target CPU at which autoscaling will be triggered.
Autoscaling enables optimal usage of resources to execute functions, by
using a baseline capacity with minimum scale and ability to burst up to
maximum scale based on spikes in demand.
Fission is an open source
project maintained by many contributors.
