The evolution of DevOps automation Since the concept of DevOps emerged around 2007 and 2008 in response to pain points with Agile development, DevOps automation has been continuously evolving. For instance, in the case of poor performance, you can seamlessly toggle a feature flag and mitigate any detrimental effects.

For many years, I explicitly advised people not to run their SQL Server workloads on AMD hardware because of the much lower single-threaded CPU performance and consequently higher SQL Server core license costs. This has led to a very noticeable reduction in generational performance increases since Broadwell-EP, as shown in Figure 1.
