### Múltiplas Aplicações

Podem existir **múltiplas aplicações** em execução no mesmo servidor (ou servidores), por exemplo: outras APIs ou um banco de dados.

Essa "espera" 🕙 é medida em microssegundos, mas ainda assim, somando tudo, é um monte de espera no final.

Por isso que faz bastante sentido utilizar código assíncrono ⏸🔀⏯ para APIs web.

Esse tipo de assincronicidade é o que fez NodeJS popular (embora NodeJS não seja paralelo) e essa é a força do Go como uma linguagem de programação.

E esse é o mesmo nível de performance que você tem com o **FastAPI**.

### Kubernetes API Reference Documentation

The API reference is now generated with [`gen-resourcesdocs`](https://github.com/kubernetes-sigs/reference-docs/tree/c96658d89fb21037b7d00d27e6dbbe6b32375837/gen-resourcesdocs) and it is moving to [Kubernetes API](https://docs.k8s.io/reference/kubernetes-api/)

### Kustomize Updates in Kubectl

 *
 * Supported on OpenJDK 9+ via SSLParameters and SSLSocket features.
 *
 * ### Trust Manager Extraction
 *
 * Supported on Android 2.3+ and OpenJDK 7+. There are no public APIs to recover the trust
 * manager that was used to create an [SSLSocketFactory].
 *
 * Not supported by choice on JDK9+ due to access checks.
 *
 * ### Android Cleartext Permit Detection

- The node.k8s.io/v1alpha1 RuntimeClass API is no longer served. Use the node.k8s.io/v1 API version, available since v1.20 ([#103061](https://github.com/kubernetes/kubernetes/pull/103061), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev)) [SIG API Machinery, CLI, Node and Testing]

### API Change

- Add 2 new options for kube-proxy running in winkernel mode. 

  try {
    this.skipAll(timeout, timeUnit)
  } catch (_: IOException) {
    false
  }

/**
 * Returns true if new reads and writes should be attempted on this.
 *
 * Unfortunately Java's networking APIs don't offer a good health check, so we go on our own by
 * attempting to read with a short timeout. If the fails immediately we know the socket is
 * unhealthy.
 *

 *
 * <ul>
 *   <li>Memory footprint has a fixed overhead (about 24 bytes per instance).
 *   <li><i>Some</i> construction use cases force the data to be copied (though several construction
 *       APIs are offered that don't).
 *   <li>Can't be passed directly to methods that expect {@code long[]} (though the most common
 *       utilities do have replacements here).
 *   <li>Dependency on {@code com.google.common} / Guava.

done in conjunction with SIG Cloud Provider, is focusing on moving internal APIs that the OpenStack (and other providers) depends upon to staging to guarantee API stability. This work also included abstracting the in-tree Cinder API and refactoring code to the external Cinder provider to remove additional Cinder volume provider code.

Additional work was also done to implement an OpenStack driver for the Cluster API effort lead by SIG Cluster Lifecycle. For the external Cloud-Provider-OpenStack...

- The kube-apiserver will no longer serve APIs that should have been deleted in GA non-alpha levels.  Alpha levels will continue to serve the removed APIs so that CI doesn't immediately break.
