I thought being an Azure Data/Database blogger I would share some amazing content from Microsoft, an Azure SQL Fundamentals learning path.

Azure SQL Database – Advanced Threat Detection
You should always seriously consider enabling this feature. This is part of the ADS suite – Advanced Data Security and I will show you how good this pro-active service is.
Azure SQL Database and Backups
Question, can you take a built-in backup ( a backup that Microsoft takes as part of the service) and create a new database from it on a NEW server in a different region?
Let’s find out.
Azure SQL Database Networking
Have you realised the changes Microsoft have made to the firewall and networking section of Azure SQL Database? I found this quite stealthy and took me by surprise. I did encounter an edge case scenario where it lead to issues once I made some tweaks but that was a rare thing.
Azure Databricks to Azure SQL DB
Recently I got to a stage where I leveraged Databricks to the best of my ability to join couple of CSV files together, play around some aggregations and then output it back to a different mount point ( based on Azure Storage) as a parquet file, I decided that I actually wanted to move this data into Azure SQL DB, which you may want to do one day.
Azure Advisor – for Azure Data Platform
Wouldn’t it be nice if we could access one main dashboard / report that pulls in information from many tools such as security centre, SQL advisor and cost management tools? Well you can, thus giving you a focal point to implement best practices, called Azure Advisor. This is not specifically for Azure SQL Database, you can leverage this for most resources within Azure. Later in this blog post you see that I will use it as a focal point for my database infrastructure in Azure.
In the Azure portal under services look for “advisor”
Azure SQL Database – Automatic Tuning – Have you enabled it?
Do you enable this setting to allow automatic tuning to care of all your performance needs? Well not ALL your needs, more so:
- CREATE INDEX
- DROP INDEX
- FORCE LAST GOOD PLAN
Deadlocks – Azure SQL Database
Would you like to troubleshoot a deadlock in Azure SQL Database? To do this you probably will be after the deadlock graph. So does this mean that you need to setup your own extended event session? No, it doesn’t.
Azure SQL Database Failover – Grace Period?
The Azure SQL Database service triggers an automatic failover after a failure is detected and the grace period has expired. What is the grace period? You can find this setting when building a failover group.
