In this chapter, we introduced the open-source development ecosystem around SQL Server on Linux and how SQL Server can help add business value to applications. We introduced the tools available for you to build and manage your data estate in Azure, including the Azure CLI and Azure Data Studio. We then looked at the platforms available to run SQL Server on Linux in Azure and some of the decision points to focus on when selecting your application's platform. We then wrapped things up with a discussion of some of the most common Azure services that can be used to build a data platform in Azure. With that, let's move on to the next chapter, which will focus on the performance of SQL Server, best practices, and how you can optimize workloads running in SQL Server on Linux in Azure.
