A Tester's Role in AIOps “AIOps” stands for “artificial intelligence in IT operations,” or using machine learning and data science to solve IT problems. AI can help with many IT functions, including detecting and remediating outages, monitoring availability and performance, and IT service management. Like with DevOps, a tester plays an important part with AIOps—they just have to determine what that is. |

Simplify Continuous Operation Tests with a Periodic Reboot Continuous operation tests find important bugs, partly as a result of their long operation and partly by increasing the probability of finding statistical bugs. However, CO tests have their own downsides. Mandating a periodic reset or reboot can work around these issues, as well as save time and cost for testing, reproduction, debugging, and fix verification. |

7 Simple Tips for Better Performance Engineering Rigorous practices to reinforce performance and resilience, and testing continuously for these aspects, are great ways to catch a problem before it starts. And as with many aspects of testing, the quality of the performance practice is much more important than the quantity of tests being executed. Here are seven simple tips to drive an efficient performance and resilience engineering practice. |

Machine Learning and Data Science for Quality and Performance Engineering
Slideshow
Managing the quality and performance of complex systems requires more than simply executing test cases and running load tests. You need to perform careful analysis of test results and production metrics. The sheer amount of data generated in production and testing makes analysis a huge challenge that is often left wanting. With the magic of machine learning (ML) and the application of data science techniques, you have the opportunity to derive valuable and actionable information from big data. Gopal Brugalette shares the basic concepts behind ML, covering clustering, classification, and predictive analysis. He shows you how to implement algorithms using open source tools and languages like Python and R. |
