This course focuses on maximizing the performance of hardware and infrastructure relating to database servers. You will learn the best ways to improve an SQL server's performance and that of its databases through infrastructure choice and configuration settings.
- Learn how to set up disks for maximum performance
- Understand how to boost file performance and how to use instant file initialization
- Understand how to optimize TempDB and choose the right VM for your workloads
- Learn how to manage an instance's resources
- Learn how to configure your database as well as your SQL Server system accounts
- Understand how to use Intelligent Query Processing to optimize database performance
- Understand the benefits of using Azure SQL Serverless
- Database administrators
- Solutions architects
- Anyone interesting in improving the performance of their database
To the most out of this course, you will need to be familiar with basic Azure concepts, have some knowledge of computer hard drives and networking, and be familiar with databases and their servers.
As I mentioned earlier, most hard drives come with a built-in memory cache, usually a few megabytes of high-speed RAM. Data recently written to disk is stored there along with the recently read data. When a disk caches data like this, it has the effect of performing above its physical limits of reading and writing to disk. Azure VMs have a feature called BlobCache, a combination of the machine's RAM and local SSD, the D drive on a Windows VM, to provide high-speed read caching for database operations. A BlobCache could be likened to a hard disk cache on steroids. This feature is only available on high-scale virtual machines in combination with premium SSDs.
Hallam is a software architect with over 20 years experience across a wide range of industries. He began his software career as a Delphi/Interbase disciple but changed his allegiance to Microsoft with its deep and broad ecosystem. While Hallam has designed and crafted custom software utilizing web, mobile and desktop technologies, good quality reliable data is the key to a successful solution. The challenge of quickly turning data into useful information for digestion by humans and machines has led Hallam to specialize in database design and process automation. Showing customers how leverage new technology to change and improve their business processes is one of the key drivers keeping Hallam coming back to the keyboard.
