ECE - Manage deployments content added (#725)

Next and hopefully final PR for ECE content
elastic/docs-projects#339

Pages to review:
- [Manage
deployments](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/725/deploy-manage/deploy/cloud-enterprise/working-with-deployments)
with all childs.

Notes:
- Tools and APIs is still in progress / pending
- We still need to integrate the information and links about managing
ECE through APIs. I haven't included any of this in my last PRs because
I don't really know where this info is. We can include that at a later
stage.

 # Change endpoint URLs [ece-administering-endpoints]
 
-For applications without SSL or HTTPS protocol support, you can use a local endpoint with the HTTP protocol, which in turn connects to your Elasticsearch cluster or to Kibana either using the HTTP or the HTTPS protocol.
+{{es}} and {{kib}} endpoint URLs are constructed using the `CLUSTER_ID` of the component ({{es}} or {{kib}}), and the domain name (`CNAME`) configured in the **Deployment Endpoints** section of the **Platform > Settings** UI.
 
-By default, cluster and Kibana endpoint URLs are constructed according to the following pattern, where `CLUSTER_ID` and `LOCAL_HOST_IP` are values that depend on your specific installation:
+By default, the deployments `CNAME` is set to `LOCAL_HOST_IP.ip.es.io`, where `LOCAL_HOST_IP` is the IP address of the first installed ECE host. This results in the following default endpoint URLs:

 Deployment templates combine components of the Elastic Stack, such as Elasticsearch nodes and Kibana instances, for different use cases. Compared to a one-size-fits-all approach to deploying the Elastic Stack, templates provide much greater flexibility and ensure that your deployments have the resources they need to support your use cases. To make the most of deployment templates, you must configure ECE for them.

+% document scope: introduction to deployment configuration use cases
+
+# Configure your deployment [ece-change-deployment]
+
+You can modify your deployment to adjust resources, enable additional features, or optimize performance. To make sure you’re all set for production, consider the following actions: 
+
+* [](./customize-deployment.md): Learn how to change your deployment architecture, configure resources, autoscaling, data tiers, and other {{stack}} components, from the **Edit** deployment view.
+* [](./edit-stack-settings.md): Add, remove, or update {{es}} or {{kib}} YML configuration settings.
+* [](./resize-deployment.md): Learn how to scale a deployment, including important considerations, and a practical example.
+* [](./add-plugins.md): Enable or disable plugins from the list of available extensions in ECE.
+* [](./add-custom-bundles-plugins.md): Add custom plugins or external configuration files to your {{es}} instances.
+* [](./ece-regional-deployment-aliases.md): Configure custom aliases to create predictable and human-readable URLs for your {{stack}} components, making them easier to share and use.
+* [](./resource-overrides.md): Temporary extend cluster capacity to improve stability.
+
+Refer to [](./working-with-deployments.md) for additional actions and configurable features for your deployments, such as snapshots, secure settings, and monitoring.
+
+## When to modify your deployment [ece-prepare-production]
+
+You might want to change the configuration of your deployment to:
+
+* Add features, such as [machine learning](/explore-analyze/machine-learning.md) or [APM (application performance monitoring)](/solutions/observability/apps/application-performance-monitoring-apm.md).
+* [Increase or decrease capacity](./resize-deployment.md) by changing the amount of reserved memory and storage for different parts of your deployment.
+* Enable [autoscaling](/deploy-manage/autoscaling/autoscaling-in-ece-and-ech.md) so that the available resources for deployment components, such as [data tiers](/manage-data/lifecycle/data-tiers.md) and machine learning nodes, adjust automatically as the demands on them change over time.
+* Enable [high availability](./ece-ha.md), also known as fault tolerance, by adjusting the number of availability zones that parts of your deployment run on.
+* [Upgrade](../../upgrade/deployment-or-cluster/upgrade-on-ece.md) to new versions of {{es}}. You can upgrade from one major version to another, such as from 8.18 to 9.0, or from one minor version to another, such as 8.16 to 8.17. You can’t downgrade versions.
+* Change what plugins are available on your deployment.
+* Update {{es}}, {{kib}}, or other stack application YML configuration settings.
+
+## Applying deployment changes
+
+When you modify a deployment and select **Save changes**, {{ece}} prepares and executes a **plan** to apply the requested updates and bring the deployment to the desired state. The type of plan depends on the nature of the changes and the selected [configuration strategy](./customize-deployment.md#configuration-strategies). Some plans involve creating new instances and migrating data, while others may require restarting certain components of the deployment.
+
+For single availability zone deployments, there is downtime to portions of your cluster when changes are applied. For [high availability](./ece-ha.md) deployments, with the exception of major version upgrades, we these changes can be made without interrupting your deployment. While these changes are being applied, you can continue to search and index.
+
+::::{note}
+When applying changes, existing data may be migrated to new nodes. For clusters containing large amounts of data, this migration can take some time, especially if your deployment is under a heavy workload. Refer to [Configuration strategies](./customize-deployment.md#configuration-strategies) to learn about the different ways ECE applies changes.

+# Connect to Elasticsearch [ece-connect]
+
+This section explains how to connect client applications to an {{es}} deployment running on ECE. You can use the [endpoint URL](#ece-connect-endpoint) available in the deployment UI, or the [Cloud ID](#ece-cloud-id) for a simplified setup with compatible clients such as Beats and Logstash.
+
+% TBD - not sure if this is totally accurate
+% {{ece}} clusters running on ECE only support connections over **HTTP/HTTPS** through the RESTful API. Direct connections to the transport port are not supported.
+
+To successfully connect to a deployment, you need both the connection details and valid authentication credentials for an authorized user in the target deployment. For more details on authentication and authorization mechanisms in ECE, refer to [Users and roles](../../users-roles.md#orchestrator-level).
+
+## Connect using the endpoint URL [ece-connect-endpoint]
+
+To connect to your {{es}} cluster, copy the **{{es}} endpoint** from the deployment page in the [Cloud UI](./log-into-cloud-ui.md).
+
+::::{important}
+Application endpoints in ECE are generated based on the domain name configured in **Platform > Settings**. To learn how to modify these endpoints, refer to [Change endpoint URLs](./change-endpoint-urls.md).
+::::
+
+Once you have the endpoint, use it in your client application. To test connectivity, you can:
+* Open the endpoint in your browser and enter authentication details when prompted.
+* Modify the following `curl` example to fit your environment by replacing the URL and proxy CA certificate with your own values.
+
+  ```sh
+  curl --cacert /path/to/elastic-ece-ca-cert.pem -u elastic https://f76e96da2a7f4d3f8f3ee25d686b879c.HOST-IP-ADDRESS.ip.es.io:9243

+
+## Connect using Cloud ID [ece-cloud-id]
+
+The Cloud ID reduces the number of steps required to start sending data from [Beats](https://www.elastic.co/guide/en/beats/libbeat/current/index.html) or [Logstash](https://www.elastic.co/guide/en/logstash/current/index.html) to your hosted {{es}} cluster on ECE, by assigning a unique ID to your cluster.
+
+::::{note}
+Connections through Cloud IDs are only supported in Beats and Logstash.
+::::
+
+
+Cloud IDs are available in every deployment page, as showed below:
+
+:::{image} ../../../images/cloud-enterprise-ec-ce-cloud-id.png
+:alt: The Cloud ID and `elastic` user information shown when you create a deployment
+:::
+
+Include this ID along with your user credentials (defined in `cloud.auth`) in your Beat or Logstash configuration. ECE will handle the remaining connection details, ensuring secure data transfer to your hosted cluster.
+
+### Before you begin [ece_before_you_begin_16]
+
+To use the Cloud ID, you need:
+
+* A deployment with an {{es}} cluster to send data to.
+* Beats or Logstash, installed locally wherever you want to send data from.
+* To configure Beats or Logstash, you need:
+    * The unique Cloud ID for your deployment, available from the deployment overview page.
+    * A user ID and password that has permission to send data to your {{es}} cluster.
+
+::::{important}
+        In our examples, we use the `elastic` superuser that every {{es}} cluster comes with. The password for the `elastic` user is provided when you create a deployment (and can also be [reset](../../users-roles/cluster-or-deployment-auth/built-in-users.md) if you forget it). On a production system, you should adapt these examples by creating a user that can write to and access only the minimally required indices. For each Beat, review the specific feature and role table, similar to the one in [Metricbeat](asciidocalypse://docs/beats/docs/reference/metricbeat/feature-roles.md) documentation.
+::::
+
+### Example: Configure Beats with your Cloud ID [ece-cloud-id-beats]
+
+The following example shows how you can send operational data from Metricbeat to a new ECE deployment by using the Cloud ID. While this example uses Metricbeat, the same approach applies to other Beats.
+
+::::{tip}
+For others, you can learn more about [getting started](asciidocalypse://docs/beats/docs/reference/index.md) with each Beat.
+::::
+
+To get started with Metricbeat and {{ece}}:
+
+1. [Log into the Cloud UI](log-into-cloud-ui.md).
+2. [Create a new deployment](create-deployment.md) and copy down the password for the `elastic` user.
+3. On the deployment overview page, copy down the Cloud ID.
+4. Set up the Beat of your choice, such as [Metricbeat](asciidocalypse://docs/beats/docs/reference/metricbeat/metricbeat-installation-configuration.md).
+5. [Configure the Beat output to send to Elastic Cloud](asciidocalypse://docs/beats/docs/reference/metricbeat/configure-cloud-id.md).
+
+    ::::{note}
+    Make sure you replace the values for `cloud.id` and `cloud.auth` with your own information.
+    ::::
+
+6. Open Kibana and explore!
+
+Metricbeat creates a data view (formerly *index pattern*) with defined fields, searches, visualizations, and dashboards that you can start exploring in Kibana. Look for information related to system metrics, such as CPU usage, utilization rates for memory and disk, and details for processes.
