>YugaPlus has become one of the top streaming platforms, with hundreds of millions of people around the world spending countless hours watching their favorite movies, series, and live events. The YugaPlus team has mastered the art of scaling in the cloud, building a service that handles user traffic with low latency across multiple regions and tolerates all sorts of possible outages.

In this chapter, you'll learn how to do the following:

* Deploy a free YugabyteDB Aeon instance.
* Connect the application to the YugabyteDB Aeon cluster.

**Prerequisites**

You need to complete [Chapter 4](../chapter4-going-global) of the tutorial before proceeding to this one.

## Start YugabyteDB Aeon cluster

[YugabyteDB Aeon](http://cloud.yugabyte.com/) is a fully managed YugabyteDB-as-a-Service that allows you to run YugabyteDB clusters on Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). The service offers a **free sandbox cluster** for everyone wishing to use YugabyteDB in a real cloud environment.

Follow these steps to deploy a free YugabyteDB Aeon instance:

1. Create a YugabyteDB Aeon account: <https://cloud.yugabyte.com/signup>

1. Begin creating the free cluster by clicking on the **Create Cluster** button.

    ![Create Cluster](/images/tutorials/build-and-learn/chapter5-create-free-cluster.png)

1. Choose the **Sandbox** cluster option:

    ![Sandbox Cluster](/images/tutorials/build-and-learn/chapter5-choose-sandbox.png)

1. Select a preferred cloud provider and region (note, Microsoft Azure is available only for paid clusters):

    ![Select Cloud](/images/tutorials/build-and-learn/chapter5-select-cloud.png)

1. Click on the **Add Current IP Address** button to add the address of your machine (where you run the YugaPlus application) to the IP Allow list:

    ![Add Address](/images/tutorials/build-and-learn/chapter5-add-your-address.png)

1. **Make sure to download** the file with your cluster credentials:

    ![Download Credentials](/images/tutorials/build-and-learn/chapter5-download-credentials.png)

1. Wait while the cluster is being created:

    ![Cluster Creation](/images/tutorials/build-and-learn/chapter5-cluster-creation-process.png)

Spinning up and configuring your sandbox instance can take up to 5 minutes. During this time, the system is preparing everything you need to get started with your YugabyteDB Aeon instance.

## Connect the application to YugabyteDB Aeon

After the YugabyteDB Aeon cluster is started, go ahead and connect the YugaPlus movie recommendations application to it.

First, rebuild the YugaPlus backend image to remove one of the database migration files created in the previous chapter:

1. Use `Ctrl+C` or run `{yugaplus-project-dir}/docker compose stop` to stop the YugaPlus application containers.

1. Rename the `V2__create_geo_partitioned_user_library.sql` file to `skip_create_geo_partitioned_user_library.sql` making sure it's not applied during the database migration phase. The YugabyteDB Aeon sandbox instance can't be used for the geo-partitioning use case that explored in chapter 4.

    ```shell
    cd {yugaplus-project-dir}/backend/src/main/resources/db/migration/
    mv V2__create_geo_partitioned_user_library.sql skip_create_geo_partitioned_user_library.sql
    ```

1. Navigate to the YugaPlus project dir:

    ```shell
    cd {yugaplus-project-dir}
    ```

1. Rebuild the Docker images:

    ```shell
    docker compose build
    ```

Next, start the application connecting to your YugabyteDB Aeon cluster:

1. Go to the YugabyteDB Aeon **Settings** tab and copy the **public** address of your cluster instance:

    ![Public Address](/images/tutorials/build-and-learn/chapter5-public-address.png)

1. Open the`{yugaplus-project-dir}/docker-compose.yaml` file and update the following settings:

    ```yaml
    - DB_URL=jdbc:yugabytedb://${YOUR_YBM_PUBLIC_ADDRESS}:5433/yugabyte?sslmode=require
    - DB_USER=${YOUR_YBM_USER}
    - DB_PASSWORD=${YOUR_YBM_PASSWORD}
    ```

    * `${YOUR_YBM_PUBLIC_ADDRESS}` - is the public address (host) of your YugabyteDB Aeon instance.
    * `${YOUR_YBM_USER}` and `${YOUR_YBM_PASSWORD}` - your database credentials from the file that you downloaded during the cluster configuration.

1. Start the application:

    ```shell
    docker compose up
    ```

As soon as the `yugaplus-backend` container starts, it applies the database migration files to your cloud database instance. You can view the created tables in the **Tables** tab of the YugabyteDB Aeon dashboard.

![Tables](/images/tutorials/build-and-learn/chapter5-movie-tables.png)

{{< note title="Can't connect to YugabyteDB Aeon?" >}}
If the application fails to connect to YugabyteDB Aeon, ensure you've added your IP address to the [IP Allow list](/stable/yugabyte-cloud/cloud-secure-clusters/add-connections).

## Ask for movie recommendations one last time

With the YugaPlus backend operational and successfully connected to your YugabyteDB Aeon cluster, do one final search for movie recommendations.

1. Go to the [YugaPlus UI](http://localhost:3000/).

1. Ask for movie recommendations:

<ul class="nav nav-tabs-alt nav-tabs-yb">
  <li>
    <a href="#full-text-search" class="nav-link active" id="full-text-search-tab" data-bs-toggle="tab"
       role="tab" aria-controls="full-text-search" aria-selected="true">
      <img src="/icons/search.svg" alt="full-text search">
      Full-Text Search
    </a>
  </li>
  <li >
    <a href="#similarity-search" class="nav-link" id="similarity-search-tab" data-bs-toggle="tab"
       role="tab" aria-controls="similarity-search" aria-selected="false">
    <img src="/icons/openai-logomark.svg" alt="vector similarity search">
      Vector Similarity Search
    </a>
  </li>
</ul>

<div class="tab-content">
  <div id="full-text-search" class="tab-pane fade show active" role="tabpanel" aria-labelledby="full-text-search-tab">
  {{% includeMarkdown "includes/chapter5-full-text-search.md" %}}
  </div>
  <div id="similarity-search" class="tab-pane fade" role="tabpanel" aria-labelledby="similarity-search-tab">
  {{% includeMarkdown "includes/chapter5-similarity-search.md" %}}
  </div>
</div>

{{< tip title="Need to troubleshoot slow queries?" >}}
And, as one last hint, if it seems that some queries are running slow, navigate to the **Performance** -> **Slow Queries** dashboard of YugabyteDB Aeon to check if any require optimization.

Congratulations! You've completed Chapter 5, the final chapter of the tutorial. Throughout this tutorial, you've learned essential capabilities of YugabyteDB that set you up for the next stage of your development journey.

Let's recap!

* You started with PostgreSQL and then leveraged YugabyteDB's [feature and runtime compatibility](../../../../explore/ysql-language-features/) with PostgreSQL by migrating to a distributed YugabyteDB cluster.
* You learned how to [tolerate various outages](../../../../explore/fault-tolerance/) by deploying a multi-region YugabyteDB cluster and using the [YugabyteDB smart driver](/stable/develop/drivers-orms/smart-drivers/).
* You used the latency-optimized [geo-partitioning design pattern](../../../build-global-apps/latency-optimized-geo-partition/) to scale both reads and writes across various locations.
* You learned how to offload the management and operations of your database cluster by migrating to [YugabyteDB Aeon](/stable/yugabyte-cloud/).

With that said, good luck building applications that scale and never fail! And don't forget to [join our community](https://inviter.co/yugabytedb), where you can get your questions answered and learn about the latest updates from the world of YugabyteDB.
