+# Overview
+
+Distributed system such as Kubernetes are designed to be resilient to the
+failures.  More details about Kubernetes High-Availability (HA) may be found at
+[Building High-Availability Clusters](https://kubernetes.io/docs/admin/high-availability/)
+
+To have a simple view the most of parts of HA will be skipped to describe
+Kubelet<->Controller Manager communication only.
+
+By default the normal behavior looks like:
+
+1. Kubelet updates it status to apiserver periodically, as specified by
+   `--node-status-update-frequency`. The default value is **10s**.
+
+2. Kubernetes controller manager checks the statuses of Kubelets every
+   `–-node-monitor-period`. The default value is **5s**.
+
+3. In case the status is updated  within `--node-monitor-grace-period` of time,
+   Kubernetes controller manager considers healthy status of Kubelet. The
+   default value is **40s**.
+
+> Kubernetes controller manager and Kubelets work asynchronously. It means that
+> the delay may include any network latency, API Server latency, etcd latency,
+> latency caused by load on one's master nodes and so on. So if
+> `--node-status-update-frequency` is set to 5s in reality it may appear in
+> etcd in 6-7 seconds or even longer when etcd cannot commit data to quorum
+> nodes.
+
+# Failure
+
+Kubelet will try to make `nodeStatusUpdateRetry` post attempts. Currently
+`nodeStatusUpdateRetry` is constantly set to 5 in
+[kubelet.go](https://github.com/kubernetes/kubernetes/blob/release-1.5/pkg/kubelet/kubelet.go#L102).
+
+Kubelet will try to update the status in
+[tryUpdateNodeStatus](https://github.com/kubernetes/kubernetes/blob/release-1.5/pkg/kubelet/kubelet_node_status.go#L345)
+function. Kubelet uses `http.Client()` Golang method, but has no specified
+timeout. Thus there may be some glitches when API Server is overloaded while
+TCP connection is established.
+
+So, there will be `nodeStatusUpdateRetry` * `--node-status-update-frequency`
+attempts to set a status of node.
+
+At the same time Kubernetes controller manager will try to check
+`nodeStatusUpdateRetry` times every `--node-monitor-period` of time. After
+`--node-monitor-grace-period` it will consider node unhealthy. It will remove
+its pods based on `--pod-eviction-timeout`
+
+Kube proxy has a watcher over API. Once pods are evicted, Kube proxy will
+notice and will update iptables of the node. It will remove endpoints from
+services so pods from failed node won't be accessible anymore.
+
+# Recommendations for different cases
+
+## Fast Update and Fast Reaction
+
+If `-–node-status-update-frequency` is set to **4s** (10s is default).
+`--node-monitor-period` to **2s** (5s is default).
+`--node-monitor-grace-period` to **20s** (40s is default).
+`--pod-eviction-timeout` is set to **30s** (5m is default)
+
+In such scenario, pods will be evicted in **50s** because the node will be
+considered as down after **20s**, and `--pod-eviction-timeout` occurs after
+**30s** more.  However, this scenario creates an overhead on etcd as every node
+will try to update its status every 2 seconds.
+
+If the environment has 1000 nodes, there will be 15000 node updates per
+minute which may require large etcd containers or even dedicated nodes for etcd.
+
+> If we calculate the number of tries, the division will give 5, but in reality
+> it will be from 3 to 5 with `nodeStatusUpdateRetry` attempts of each try. The
+> total number of attemtps will vary from 15 to 25 due to latency of all
+> components.
+
+## Medium Update and Average Reaction
+
+Let's set `-–node-status-update-frequency` to **20s**
+`--node-monitor-grace-period` to **2m** and `--pod-eviction-timeout` to **1m**.
+In that case, Kubelet will try to update status every 20s. So, it will be 6 * 5
+= 30 attempts before Kubernetes controller manager will consider unhealthy
+status of node. After 1m it will evict all pods. The total time will be 3m
+before eviction process.
+
+Such scenario is good for medium environments as 1000 nodes will require 3000
+etcd updates per minute.
+
+> In reality, there will be from 4 to 6 node update tries. The total number of
+> of attempts will vary from 20 to 30.
+
+## Low Update and Slow reaction
+
+Let's set `-–node-status-update-frequency` to **1m**.
+`--node-monitor-grace-period` will set to **5m** and `--pod-eviction-timeout`
+to **1m**. In this scenario, every kubelet will try to update the status every
+minute. There will be 5 * 5 = 25 attempts before unhealty status. After 5m,
+Kubernetes controller manager will set unhealthy status. This means that pods
+will be evicted after 1m after being marked unhealthy. (6m in total).
+
+> In reality, there will be from 3 to 5 tries. The total number of attempt will
+> vary from 15 to 25.
+
+There can be different combinations such as Fast Update with Slow reaction to
+satisfy specific cases.
