Databases are fundamental to every application, and reading or writing data in a quick and reliable way is critical to ensuring happy users. Your shiny new application may have worked well in the beginning, but with more and more people using the app the response times may take a nose dive. Or, what if you push a great new feature, guaranteed to make customers happy, but then it doesn’t scale or it actually degrades the performance of existing functionality? What do you do? How do you diagnose and resolve these issues in a timely and cost efficient manner? Whilst many organizations employ a team of database administrators (DBAs) to manage database performance, it’s often a group separated from development and operational support with their own tools, scripts, and procedures. This creates inefficiency in the root cause analysis process. We want to empower customers by including deep-dive database monitoring as part of end-to-end APM, thereby providing immediate visibility of DB metrics to all groups within IT. This session covers: -Why it makes sense to include the database as part of API -What are some real world problems affecting database performance -What is a good methodology for diagnosing and understanding database performance This deck was originally presented at AppSphere 2015.

If you look at data store as just another service, the things applications care about are successfully establishing a connection and getting results to the queries promptly and with correct results. In this presentation, we will explore this seemingly simple aspect of working with database in details. We will talk about why you want to go beyond the averages, and how to group queries together in the meaningful way so you’re not overwhelmed with amount of details but find the right queries to focus on. We will answer the question on when you should focus on tuning specific queries or when it is better to focus on tuning the database (or just getting a bigger box). We will also look at other ways to minimize user facing response time, such as parallel queries, asynchronous queries, queueing complex work, as well as often misunderstood response time killers such as overloaded network, stolen CPU, and even limits imposed by this pesky speed of light.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
