SQL Server Stretch DB to Azure

Since SQL Server 2016 we could leverage Microsoft Azure to dynamically move “cold” portions of data away from on-premises storage for longer retention time periods. Whilst in theory being a great idea the cost was a blocker for some and with a cumbersome setup process. SQL Server 2019 addresses this by making the costs of storing the data in the cloud more competitive and making the setup more streamlined with the use of the Data Migration Assistant (DMA) tool and SSMS (SQL Server Management Studio).

Note: DMA tool replaces the older Upgrade Advisor tool. To install DMA please see the following link https://docs.microsoft.com/en-us/sql/dma/dma-overview?view=sql-server-ver15.

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.

Backup Techniques for SQL Server on Azure Virtual Machines

In the previous blog post I did a quick overview building a SQL VM (imaged) in Azure. It is now time to clarify some backup techniques because it can get confusing.

At a high level there are 3 techniques.

  • Automated backup.
  • Azure backup for SQL VM (that’s what MS call it).
  • Manual backup, for example backup to URL.

I prefer not setting up manual backups to storage accounts, I have done it, I just find it painful to  setup/support/fix. So my choice would be automated backup vs “Azure backup” for SQL VM. What’s the difference?

SQL Server Virtual Machines in Azure

Let’s create a virtual machine in Azure that has an imaged copy of SQL Server on it. I want to do this because down the line I want to show how you can setup automated backups to a storage account based on an IaaS extension, when I do that I will most likely talk about the different backup options because there are many.

SQL Server Management Studio

Hopefully you know that SSMS is a separate install from the main SQL Server install. You can find the binaries from Microsoft (https://docs.microsoft.com/en-us/sql/ssms/download-sql-server-management-studio-ssms) Using SSMS version 18.2, whilst playing around with the options I noticed a dark theme was available, easy to say I got a little excited, then I didn’t.

SQL server and Java?

I was generally reading about SQL Server and how things have changed since the days of just having it within a Windows Eco-system only. It then led me to a cool website, SQL Server development – build an app using SQL server where you can get to see the high-level requirements of starting to build a solution based on a wide variation of languages and operating systems. https://www.microsoft.com/en-us/sql-server/developer-get-started/

There are many combinations possible with SQL Server being the back-end database of choice.

SQL Server – max server memory

Another re-post of a video from last year, this time showing you an in-built protection of setting max server memory for your SQL Server. You can clearly see that if you enter a silly figure such as 50 MB, the minimum memory amount allowable for max server memory is 128 MB. You will see SSMS (SQL Server Management Studio) change it to 128MB.
