apps may target different 'environments' which contain different instances and variants of Istio.

- Better security: separate Istio components reside in different namespaces, allowing different teams or
roles to manage different parts of Istio. For example, a security team would maintain the
root CA and policy, a telemetry team may only have access to Prometheus,

```

**`kube.Client`** is a fairly light wrapper around Kubernetes clients, but offers quite a few benefits.
Istio consumes _many_ different types of clients (at the time of writing, 7), as well as informers for each of these.
Additionally, we often need to convert to various different client forms for different libraries we integrate with.

## Origin

An origin is the combination of protocol (`http`, `https`), domain (`myapp.com`, `localhost`, `localhost.tiangolo.com`), and port (`80`, `443`, `8080`).

So, all these are different origins:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

	}
	return s
}

// quoteChar formats c as a quoted character literal
func quoteChar(c byte) string {
	// special cases - different from quoted strings
	if c == '\'' {
		return `'\''`
	}
	if c == '"' {
		return `'"'`
	}

	// use quoted string with different quotation marks
	s := strconv.Quote(string(c))
	return "'" + s[1:len(s)-1] + "'"

## Gradle runtimes

Gradle is also made up of several different processes that work together to "run the build", such as the Gradle daemon and the `gradlew` command.

Each process, or "runtime", applies different constraints to the code that runs in that process.
For example, each process has different supported JVMs and a different set of services available for dependency injection.

		{cred, Credentials{}, false},
		// Empty credentials.
		{Credentials{}, cred, false},
		// Two different credentialss
		{cred, cred2, false},
		// Access key is different in credentials to compare.
		{cred, Credentials{AccessKey: "myuser", SecretKey: cred.SecretKey}, false},
		// Secret key is different in credentials to compare.
		{cred, Credentials{AccessKey: cred.AccessKey, SecretKey: "mypassword"}, false},
	}

In this case, it requires the scope `me` (it could require more than one scope).

/// note

You don't necessarily need to add different scopes in different places.

We are doing it here to demonstrate how **FastAPI** handles scopes declared at different levels.
