Fly.io outage, recently deployed apps down, no new deployments possible
ByteDance replaces etcd with kubebrain [1], which is backed by their own KV store (TiKV seems also supported).
The single-group raft is the hard limit.

Do EKS or GKE use etcd?
Interesting...as i wrote this kubebrain is OSs you can find it here: https://github.com/kubewharf/kubebrain They basically implemented the etcd client API and replaced the backend with tikv I was thinking that might be interesting to add support for dynamodb or crdb

A Detailed Brief About Offence and Defence on Cloud Security - Etcd Risks
When building Kubernetes and configuring the Etcd service, if there is a misconfiguration or vulnerability risk point mentioned in the previous chapter, an attacker can use the Etcd risk point to launch an attack. We list the common attack methods of attackers here, and guide readers to understand the risks and threats faced by the Etcd service by means of attack and defense. Before we start to introduce common attacks, let's first understand a common etcd command line tool - etcdctl. etcdctl is a command line client that provides some concise commands. Users can interact with etcd services directly using the commands provided by etcdctl without using the HTTP API. It can be downloaded from the following address: https://github.com/coreos/etcd/releases Next, we analyze several attack scenarios one by one. the exposure way of public network

Using etcd as primary store/database?
Can etcd be used as reliable database replacement? Since it is distributed and stores key/value pairs in a persistent way, it would be a great alternative nosql database. In addition, it has a great API. Can someone explain why this is not a thing?

rqlite, the light distributed database built with Go and SQLite, v7.2 now with autoclustering via DNS and DNS SRV
rqlite gives you the functionality of a rock solid, fault-tolerant, replicated relational database, but with very easy installation, deployment, and operation. With it you've got a lightweight and reliable distributed relational data store. Think etcd or Consul, but with relational data modelling also available.
