/**
 * A certificate chain cleaner that uses a set of trusted root certificates to build the trusted
 * chain. This class duplicates the clean chain building performed during the TLS handshake. We
 * prefer other mechanisms where they exist, such as with
 * [okhttp3.internal.platform.AndroidPlatform.AndroidCertificateChainCleaner].
 *
 * This class includes code from [Conscrypt's][Conscrypt] [TrustManagerImpl] and

# Writing Tests for VMs

This document describes the integration and extension mechanisms to exercise VM related code.
The primary goals are to:
1. Test VM-related Istio code so that newly submitted commits won't break VM support
1. Ensure the code works on a range of supported OS types and versions.

**Note: We currently use mock/simulated VMs for testing purposes. In the future, the testing might switch
to utilize actual compute instances from different providers.**

Kubernetes, also known as K8s, is an open source system for managing [containerized applications]
across multiple hosts. It provides basic mechanisms for the deployment, maintenance,
and scaling of applications.

Kubernetes builds upon a decade and a half of experience at Google running
production workloads at scale using a system called [Borg],

mechanisms that prevent unwanted access to the data from other tenants.

Network isolation between different models is also important not only to prevent
unauthorized access to data or models, but also to prevent malicious users or
tenants sending graphs to execute under another tenant’s identity.

The isolation mechanisms are the responsibility of the users to design and

	// connection later
	conn net.Conn
	// whether the Client is using TLS
	tls        bool
	serverName string
	// map of supported extensions
	ext map[string]string
	// supported auth mechanisms
	auth       []string
	localName  string // the name to use in HELO/EHLO
	didHello   bool   // whether we've said HELO/EHLO
	helloError error  // the error from the hello
}

A queue is used to give a few properties:
* Ability to serially process updates received from a variety of different sources. This avoids need for other synchronization mechanisms like mutexes.
* Correctness at startup; with the sequencing above, items are only processed once all informers are synced. This means queries will not return stale data at startup.
* Deduping of identical events

## **FastAPI** utilities

FastAPI provides several tools for each of these security schemes in the `fastapi.security` module that simplify using these security mechanisms.

In the next chapters you will see how to add security to your API using those tools provided by **FastAPI**.

 * Gradle generates implementations for managed types.
 * As such, managed types are declared either as interfaces or abstract classes.
 * The generated implementation integrates with the model space mechanisms, and manages mutability.
 * <p>
 * Managed types are mostly behaviour-less, as they are data.
 * Instances of managed types should effectively be considered value objects.
