Mixer out-of-process adapter for Knative
Demonstrates a Mixer out-of-process adapter which implements the Knative scale-from-zero logic. This post demonstrates how you can use Mixer to push application logic into Istio. It describes a Mixer adapter which implements the Knative scale-from-zero logic with simple code and similar performance to the original implementation.
Knative Serving builds on Kubernetes to support deploying and serving of serverless applications. A core capability of serverless platforms is scale-to-zero functionality which reduces resource usage and cost of inactive workloads. A new mechanism is required to scale from zero when an idle application receives a new request.
