My previous post on load testing Azure SQL covered the Standard Edition; today I'm moving to the Premium Edition, which is Business Critical in DTU shape. Again, the calculation mixes CPU, Memory, and disk I/O. The main difference between Standard and Premium is cost. Premium is more expensive and aimed at mission-critical workloads. It has … Continue reading Loadtesting SQL: The Sequel: Premium Edition
This series of posts is much overdue, but with good reason. When I started hammering Azure SQL again, I had a set of scripts to run and tried to figure out what was happening. For most databases, I could explain the results, but some didn't make sense. I'll get back to that later in this … Continue reading Load testing SQL, the sequel. Standard Edition

Wait, what? Resiliency? Against what? Well. The cloud sounds like an amazing, magical place without limits. The truth is, it isn't. Maybe you've seen the funny T-shirts with the text "the cloud is just someone else's computer". And that's true. Instead of building and maintaining your own data centre, you're hiring a global corporation to … Continue reading Azure: Check your data platforms resiliency

Whatever your association with database mirroring, it is also available within Microsoft Fabric. What is mirroring If you're not coming from a SQL Server background, or any data … Continue reading DP-700 training: Implement mirroring
Some time ago, I wrote a number of blogposts comparing the different Azure SQL options to give you some idea about performance, differences between tiers and differences between the Stock Keeping Units (SKU's). This was done by creating data in the database itself and review the metrics. This works fine and gave a good overview … Continue reading Loadtesting SQL, the sequel
Data security is the most important part of our job as data engineers and data architects. There are very few use cases where people need to see all the data in full detail. I know, customers take a different view on this but in reality, do they really need every single detail? No, they do … Continue reading DP-700 training: data masking
This blog won't be very long and will describe a connection issue I experienced with a customer including the solution and some context why this solution worked.

Issue The customer can connect to the Azure Sql database with Sql Server Management Studio (SSMS) … Continue reading Fixing Azure SQL Client Connection Timeouts
After an almost full week of travelling, learning and meeting people, time for a short write up. Hello Stockholm! Or even hello Schiphol. When I walked up to the gate, it took the best part of a minute for the first Microsoft person to walk up to me and ask if I was on my … Continue reading Experiencing Microsoft Fabric Conference in Stockholm
