Azure SQL Database is suitable for hosting Relational databases.

Here's why:

1. Azure SQL Database is a fully managed platform as a service (PaaS) Database Engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement.

2. It is based on the latest stable version of the Microsoft SQL Server database engine and capable of handling relational data.

3. It provides the ability to query relational data, which is not possible with NoSQL databases.

4. In-memory databases are typically used for applications that require microsecond response times, and while Azure SQL Database does support in-memory OLTP, it's not its primary function.

5. Azure SQL Database is not designed to handle scalable binary data. Services like Azure Blob Storage would be more suitable for that purpose.
