-# Implementations
-
-## Resource Metrics API
-
-- [Heapster](https://github.com/kubernetes/heapster): a application which
-  gathers metrics, writes them to metrics storage "sinks", and exposes the
-  resource metrics API from in-memory storage.(Heapster is now deprecated. See the [deprecation timeline](https://github.com/kubernetes-retired/heapster/blob/master/docs/deprecation.md) for more information on support.)
-
-- [Metrics Server](https://github.com/kubernetes-incubator/metrics-server):
-  a lighter-weight in-memory server specifically for the resource metrics
-  API.
-
-## Custom Metrics API
-
-***NB: None of the below implementations are officially part of Kubernetes.
-They are listed here for convenience.***
-
-- [Prometheus
-  Adapter](https://github.com/kubernetes-sigs/prometheus-adapter).  An
-  implementation of the custom metrics API that attempts to support
-  arbitrary metrics following a set label and naming scheme.
-
-- [Microsoft Azure Adapter](https://github.com/Azure/azure-k8s-metrics-adapter). An implementation of the custom metrics API that allows you to retrieve arbitrary metrics from Azure Monitor.
-
-- [Google Stackdriver (coming
-  soon)](https://github.com/GoogleCloudPlatform/k8s-stackdriver)
-
-- [Datadog Cluster Agent](https://github.com/DataDog/datadog-agent/blob/c4f38af1897bac294d8fed6285098b14aafa6178/docs/cluster-agent/CUSTOM_METRICS_SERVER.md).
-  Implementation of the external metrics provider, using Datadog as a backend for the metrics.
-  Coming soon: Implementation of the custom metrics provider to support in-cluster metrics collected by the Datadog Agents.
-
-- [Kube Metrics Adapter](https://github.com/zalando-incubator/kube-metrics-adapter). A general purpose metrics adapter for Kubernetes that can collect and serve custom and external metrics for Horizontal Pod Autoscaling.
-  Provides the ability to scrape pods directly or from Prometheus through user defined queries.
-  Also capable of serving external metrics from a number of sources including AWS' SQS and [ZMON monitoring](https://github.com/zalando/zmon).
-
-## External Metrics API
-
-***NB: None of the below implementations are officially part of Kubernetes.
-  They are listed here for convenience.***
-
- - [KEDA](https://github.com/kedacore/keda). A Kubernetes-based Event Driven Autoscaling component. It provides event driven scale for any container running in Kubernetes.
