# Hosting options

First of all, Acknowledgement will be installed in your Microsoft 365 tenant. The tool is based on an **SQL database** where acknowledgement data is stored. 

{% hint style="info" %}
The database costs **€4.50** **per month** for 2GB of storage, which is sufficient for small businesses. Larger companies may require more storage, in which case the cost increases to €13.60 per month.
{% endhint %}

Regarding the available hosting options, the tool can be installed in **SaaS** or **self-hosted** mode.

### SaaS

To install the SQL database**,** an **Azure subscription is required**. SaaS customers can choose between two options:

* **If you already have an active Azure subscription** and would like to use it, we will ask you to create a **Resource Group** for the database and grant us **Contributor** permissions. These permissions are needed to access the subscription and install the database.
* **If you don’t have an Azure subscription**, we can provide one for you**.** In this case, we will activate a **new pay-as-you-go Azure subscription**. After that, our technical specialist will contact you to obtain access and install the database. Specifically, our specialist will need to work with someone who has a **Global Administrator** role to assign **our account** as the **owner** of the subscription.

### Self-hosted

In the case of the self-hosted setup, we can generally proceed autonomously with the installation of the application and the database. We will leverage the same **Azure subscription** and the existing **resource group** already used for the other **intranet.ai resources**. We will contact you in case any specific actions are required from your side.
