This guide details the management of incoming and outgoing connections (incoming and outgoing connections) between your different hosting environments, specifically for remote access to databases.

Database connections between hostings

1. From a Web Hosting (Shared)

If you have a Web Hosting (except for the old offer "v1 - 60 Go"), you can establish a connection to databases located on:

• another Web Hosting (shared),
• a Cloud Server type hosting.

This flexibility allows you to share a database between multiple sites, establish remote connections, or configure cross-access between your services.

2. From a Cloud Server

With a Cloud Server, it is possible to connect to databases hosted on another Cloud Server in your fleet:

• Make sure that port 3306 (protocol TCP) is open for incoming traffic in your firewall.
• If you restrict access to certain addresses, check the rules for the IPv4 and IPv6 protocols.

Important note: outgoing connections from a Cloud Server to the databases of a shared hosting are not allowed.

3. From an external provider

If you want to access your MySQL databases from a server or a tool located outside the Infomaniak infrastructure (third-party provider, local application, etc.), refer to this other guide.
