On top of this, the Linux version also supports several additional cloud functions related to Azure. Specifically include:

• Azure Synapse link support,Enables developers to easily and directly access the Azure Cosmos DB analytical store using Azure Synapse Analytics.“The Integration Runtime (IR) cannot be installed in a Linux environment, so you must run the IR on a Windows-based computer that is on the same network as the Linux computer running the instance of SQL Server it connects to.“

The foreign media The Register pointed out that software engineers are leaning towards open source databases. A Stack Overflow survey of about 70,000 programmers this year found that almost all of them are using one of the two top open source relational database management systems, either PostgreSQL (46.5%) or MySQL (45.7%) or some other open source database .“As a result, Microsoft continues to add features and functionality to SQL Server for Linux and make it a growing part of its Azure enterprise cloud service, which makes sense in a rapidly evolving IT world that is increasingly crossCloud and distributed support.“
