Эта книга научит вас поддерживать решения Power BI любой степени сложности с минимальными усилиями. Вы узнаете, как проводить оптимизацию на всех слоях Power BI - начиная с рабочей области отчета и заканчивая моделированием данных, их преобразованием, хранением и архитектурой. Выясните, что необходимо сделать, чтобы при масштабировании проекта не страдало его быстродействие. Научитесь определять распространенные ошибки на этапе проектирования данных, приводящие к снижению эффективности решения и расходованию лишней памяти. Мы рассмотрим все настройки, которые могут негативно сказываться на производительности. Вместе мы пройдем по всем слоям типичного решения Power BI и узнаем, что необходимо сделать, чтобы при масштабировании проекта не страдало его быстродействие. Начнем мы со слоя данных и постепенно поднимемся до уровня дизайна отчетов. Попутно мы рассмотрим варианты лицензирования Power BI Premium, включая процесс планирования загрузки и нагрузочное тестирование, и поговорим о службах Azure, позволяющих обеспечить дополнительное масштабирование.

The integration of fog computing with the resource-limited Internet of Things (IoT) network formulates the concept of the fog-enabled IoT system. Due to a large number of IoT devices, the IoT is a main source of Big Data. A large volume of sensing data is generated by IoT systems such as smart cities and smart-grid applications. A fundamental research issue is how to provide a fast and efficient data analytics solution for fog-enabled IoT systems. Big Data Analytics in Fog-Enabled IoT Networks: Towards a Privacy and Security Perspective focuses on Big Data analytics in a fog-enabled-IoT system and provides a comprehensive collection of chapters that touch on different issues related to healthcare systems, cyber-threat detection, malware detection, and the security and privacy of IoT Big Data and IoT networks. This book also emphasizes and facilitates a greater understanding of various security and privacy approaches using advanced Artificial Intelligence and Big Data technologies such as Machine Learning and Deep Learning, Federated Learning, blockchain, and edge computing, as well as the countermeasures to overcome the vulnerabilities of the fog-enabled IoT system.

Support ATA Learning and its writers and learn how to get a jumpstart on building PowerShell functions from PowerShell subject matter experts! Take your PowerShell skills to the next level with functions! Functions are a core component of PowerShell and a topic you must understand to build great PowerShell tools. This tutorial-based guidebook contains independent PowerShell tutorials written with the beginner in mind by PowerShell subject matter experts to help you understand how functions work and how to get started creating them today! Once you get accustomed to writing PowerShell scripts, you need to learn about code modularization. Modularization is just a fancy word for creating code in building blocks. In the PowerShell world, PowerShell functions are one of the best ways to do this. When you write a PowerShell script, you have many options on how you write the code. You could write a thousand lines of code that do hundreds of tasks, all in a single, uninterrupted block of code. That would be a disaster. Instead, you should write functions. Functions dramatically increase the usability and readability of your code, making it much easier to work with.

Working effectively with Apple platforms at a corporate or business level includes not only infrastructure, but a mode of thinking that administrators have to adopt to find success. A mode of thinking that forces you to leave 30 years of IT dogma at the door. This book is a guide through how to integrate Apple products in your environment with a minimum of friction. Because the Apple ecosystem is not going away. You'll start by understanding where Apple, third-party software vendors, and the IT community is taking us. What is Mobile Device Management and how does it work under the hood. By understanding how MDM works, you will understand what needs to happen on your networks in order to allow for MDM, as well as the best way to give the least amount of access to the servers or services that’s necessary. You'll then look at management agents that do not include MDM, as well as when you will need to use an agent as opposed to when to use other options. Once you can install a management solution, you can deploy profiles on a device or you can deploy profiles on Macs using scripts.
