# Overview

IONOS Cloud Database as a Service (DBaaS) MongoDB is a fully managed MongoDB hosting service that handles provisioning, backups, patching, and monitoring—so you can focus on your application.

MongoDB is a leading NoSQL database solution, engineered for high performance, seamless scalability, and schema flexibility. It is specifically designed to handle the complexities of modern, data-intensive applications and large-scale datasets.

To support a wide range of professional use cases, IONOS Cloud offers specialized tiers, including **MongoDB Business** and **MongoDB Enterprise**, each tailored to deliver the reliability and advanced features required for production-ready, enterprise-level deployments.

You can try out MongoDB for free with the **MongoDB Playground** edition and further upgrade to the **MongoDB Business** and **MongoDB Enterprise** editions. Use the [<mark style="color:blue;">Sizing</mark>](/cloud/databases/mongodb/overview/sizing.md) methodology to identify the starting configurations based on the workload size and select the suitable edition.

{% hint style="info" %}
**Note:** To scale resources in the **MongoDB Enterprise** edition, contact [<mark style="color:blue;">IONOS Cloud Support</mark>](https://docs.ionos.com/cloud/support/general-information/contact-information) for assistance with this feature.

### Which MongoDB edition on IONOS Cloud should I use?

To ensure your database performs optimally from day one, we recommend following our [<mark style="color:blue;">Sizing</mark>](/cloud/databases/mongodb/overview/sizing.md) methodology. It helps you identify your initial configuration based on the following:

* **Workload size:** Evaluating your data volume and throughput.
* **Performance requirements:** Matching RAM and CPU to your specific application needs.
* **Edition selection:** Aligning business requirements (like advanced security or specific SLAs) with the appropriate tier.

| **If you need**                                                    | **Choose**             |
| ------------------------------------------------------------------ | ---------------------- |
| Free sandbox for development                                       | **MongoDB Playground** |
| Production workloads up to 128 GB RAM and 1.28 TB storage          | **MongoDB Business**   |
| Sharding, dedicated cores, up to 230 GB RAM, or up to 4 TB storage | **MongoDB Enterprise** |

## Architectural stack

The diagram illustrates the architectural stack of IONOS Cloud MongoDB, moving in a top-down approach from the Client and Application Layer to the physical hardware.

![IONOS Cloud DBaaS MongoDB](/files/oPGlTY3tEC7s6adbKpK7)

The four key layers are as follows:

<details>

<summary><strong>Application Layer</strong></summary>

Represents your web apps and microservices.

* **MongoDB Query Language (MQL):** The native language used to connect to the database. Since this is "Managed MongoDB," you use standard MQL—no proprietary language is required.
* **SDKs and APIs:** You can manage the database programmatically, such as create, delete, or resize instances using IONOS Cloud-specific tools.

</details>

<details>

<summary><strong>Managed Service Layer</strong></summary>

Represents the operations handled by IONOS Cloud.

* **Load Balancing:** It automatically directs traffic to the healthiest nodes.
* **Metrics and Monitoring:** Continuous 24/7 monitoring that alerts the system if a node fails.
* **Infrastructure as Code (IaC):** Supports tools, such as Terraform or Ansible, to deploy databases through scripts.
* **Security Patches and Updates:** Supports automatic updates for the MongoDB engine and the underlying OS, eliminating the need for manual version upgrades.

{% hint style="info" %}
**Note:** For detailed services managed by IONOS Cloud, see [<mark style="color:blue;">FAQ</mark>](/cloud/databases/mongodb/mongodb-faq.md#as-a-managed-service-which-services-are-handled-by-ionos-cloud).
{% endhint %}

</details>

<details>

<summary><strong>Database Cluster Layer</strong></summary>

Focuses on data integrity and High Availability (HA).

* **Replica Set:** Consists of a **Primary Node**, where data is written, and a **Secondary Node**, where data is copied. If the primary node fails, a secondary node takes over instantly.
* **Sharding Cluster:** Represents horizontal scaling. If your data becomes too large for the replica set, it is sharded (split) across multiple servers to maintain speed. Only **MongoDB Enterprise** supports full horizontal scaling with Sharding.

{% hint style="info" %}
**Note:** For detailed replication and sharding capabilities based on MongoDB editions, see [<mark style="color:blue;">Editions</mark>](/cloud/databases/mongodb/overview/editions.md).
{% endhint %}

</details>

<details>

<summary><strong>Underlying Infrastructure</strong></summary>

Represents the physical resources behind the MongoDB service.

* **Dedicated vCPU and Cores:** The dedicated CPU resources that are allocated to your MongoDB operations. **MongoDB Business** works on [<mark style="color:blue;">Cubes</mark>](/cloud/compute-services/cubes.md), and **MongoDB Enterprise** works on [<mark style="color:blue;">Dedicated Core Servers</mark>](/cloud/compute-services/compute-engine/dedicated-core.md).
* **RAM (up to 230 GB):** High-memory availability for fast, in-memory processing of large datasets.
* **Storage (up to 4 TB):** Storage resources are allocated based on the selected MongoDB edition. With MongoDB Enterprise, the platform provides up to 4 TB (4,000 GB) of storage.

## Supported integrations

MongoDB is fully integrated into the [<mark style="color:blue;">Data Center Designer</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#data-center-designer-dcd). You may also manage it through automation tools like [<mark style="color:blue;">Terraform</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#terraform) and [<mark style="color:blue;">Ansible</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#ansible).
