SQL Azure is Microsoft's cloud-based relational database that is compatible with SQL Server and accessible from many programming languages. It has limitations compared to SQL Server, such as a maximum database size of 10GB and lack of features like CLR, filegroups and replication. Migration tools can help modify schemas and scripts to be compatible with SQL Azure.
