Topics on how we testing Windows Azure SQL Database Series
I think Windows Azure SQL Database , which used to called SQL Azure, and internally we called CloudDB is an amazing service that it was the first multi tenant cloud based SQL database. As you can image, it is super complex under the hook, and we sometime thought the architect is not suitable for modern service. However, running such complex service is sometime fun and frustrated (when you are on called for one week, and been called up 3 or 4 time per night). it always has big challenge and you can learn lot from it. In this blog series, I will write a couple of ideas focusing on how we testing SQL Azure. Note, most of the ideas are not mine, I just have pleasure to work with many people who invent and implemented them. Hope this can help your team to better testing your service.
Here is topics I plan to write and I am pretty sure that I will not follow the order to write my blogs since some topics are much hard to write than others.
