Описание: Meet the challenge of storing and accessing analytic data in SQL Server in a fast and performant manner. This book illustrates how columnstore indexes can provide an ideal solution for storing analytic data that leads to faster performing analytic queries and the ability to ask and answer business intelligence questions with alacrity. The book provides a complete walk through of columnstore indexing that encompasses an introduction, best practices, hands-on demonstrations, explanations of common mistakes, and presents a detailed architecture that is suitable for professionals of all skill levels. With little or no knowledge of columnstore indexing you can become proficient with columnstore indexes as used in SQL Server, and apply that knowledge in development, test, and production environments. This book serves as a comprehensive guide to the use of columnstore indexes and provides definitive guidelines. You will learn when columnstore indexes should be used, and the performance gains that you can expect. You will also become familiar with best practices around architecture, implementation, and maintenance. Finally, you will know the limitations and common pitfalls to be aware of and avoid. As analytic data can become quite large, the expense to manage it or migrate it can be high. This book shows that columnstore indexing represents an effective storage solution that saves time, money, and improves performance for any applications that use it. You will see that columnstore indexes are an effective performance solution that is included in all versions of SQL Server, with no additional costs or licensing required. What You Will Learn * Implement columnstore indexes in SQL Server * Know best practices for the use and maintenance of analytic data in SQL Server * Use metadata to fully understand the size and shape of data stored in columnstore indexes * Employ optimal ways to load, maintain, and delete data from large analytic tables * Know how columnstore compression saves storage, memory, and time * Understand when a columnstore index should be used instead of a rowstore index * Be familiar with advanced features and analytics Who This Book Is For Database developers, administrators, and architects who are responsible for analytic data, especially for those working with very large data sets who are looking for new ways to achieve high performance in their queries, and those with immediate or future challenges to analytic data and query performance who want a methodical and effective solution

Описание: In order to deploy and use Microsoft Certificate Services, you need to understand the fundamentals of cryptography, digital signatures, encryption, TLS, and S/MIME. It is also important to understand the concepts behind public key infrastructure (PKI). This book teaches you all the required background knowledge you need. Then it takes you deeper, step by step, teaching you how to deploy Certificate Services and configure it to issue various digital certificate types, complete with examples of using these certificates with IIS, Outlook, and Windows. Microsoft-based networks—on-premises, hybrid, and cloud-based networks—are used in companies of all sizes. Within them, there are many applications of digital certificates that can be created and managed by Microsoft Certificate Services. As security is more important than ever, and cryptography and PKI are fundamental to so many of these defenses, understanding Microsoft Certificate Services is becoming an increasingly more desirable skill. Most IT workers don’t realize the many uses and purposes of Certificate Services, especially within a corporate or government agency network, and how tightly integrated they are with the Microsoft Windows Domain style of networks and Active Directory (on-premises or cloud-based, including Azure, AWS, and Google Cloud Services). This book will teach you the gamut. You will appreciate the learning approach presented in the book, beginning with the basics (cryptographic primitives such as encryption and message digests), getting into combinations of primitives to accomplish specific things (such as digital signatures and envelopes), and then trying real-word systems based on digital certificates and PKI (such as TLS, S/MIME secure email, cryptographic authentication, and more). The book wraps it all up and teaches you how to deploy Certificate Services and issue the various types of certificates, including how they are used. What You Will Learn * Understand basic cryptography (symmetric and asymmetric key encryption, message digests, and digital signatures and envelopes) * Know how TLS, S/MIME, and cryptographic authentication work * Discover applications of cryptography related to secure servers with TLS and cryptographic (passwordless) authentication to online services including Windows and secure email * Get to know the common types of digital certificates, how to create and manage them, and examples of their use with IIS, Outlook, etc. Who This Book Is For Microsoft system and network engineers, security engineers, and CISOs. Readers should have familiarity with Windows Server 2019 (or more recent) and Active Directory.
