Using Power BI Desktop to Visualize SQL Server Metadata
You can easily use PowerBI Desktop to show graphically how your database is growing, which tables are taking the most space, how various parts of SQL Server is consuming memory, its use of indexes and so on. Sure, you can create graphs in SSMS, but with PowerBI, you can create reports that you can then publish to others, and which allow drill-down. It is a great way to get familiar with PowerBI Desktop as well. Rob Sheldon shows how simple it is to do.
Scrubbing Personally Identifiable Information
Managing personally identifiable information when moving databases to unsecure environment can be challenging. With this flexible and extendable solution for scrubbing it, you can save yourself some time and effort.
Configure SQL Server AlwaysOn Availability Group on a Multi-Subnet Cluster
A “multi-subnet” environment is defined when the OS cluster used as the backbone for AlwaysOn has server nodes that are located in multiple/different subnets. Deploying SQL Server AlwaysOn Availability Groups requires a Windows Server Failover Clustering (WSFC) cluster and each availability replica of a given availability group must reside on a different node of the same WSFC cluster. This post from Manvendra Singh will help you in configuring an HA and DR solution for SQL Server AlwaysOn in multi-subnet networks.
