Use Cases and Deployment Scope
I primarily use Microsoft SQL Server 2019 and 2022 data engine to run commercial workloads of various customers. A frequent configuration use case is the usage of Microsoft SQL Server Always On failover cluster instances to provide high availability and redundancy at the Microsoft SQL Server instance level. In some cases, I also make use of Microsoft SQL Server replication to ensure that a primary (publisher) database is replicated, by using transaction of snapshot replication, to a subscriber SQL instance from which the customer can run various SQL queries for analytical reporting purposes without affecting the SQL production workloads. Another common case where I make use of Microsoft SQL Server is when running hybrid cloud SQL workloads, in which case I combine on-premise SQL Server deployments, Azure VM-based SQL Server deployments and Azure SQL or Azure SQL Managed Instance resources.
