Azure Arc-Enabled Data Services Revealed

Get introduced to Azure Arc-enabled data services and the powerful capabilities they provide to deploy and manage local, on-premises, and hybrid cloud data resources using the same centralized management and tooling you get from the Azure cloud. This book shows how you can deploy and manage databases running on SQL Server and Postgres in your corporate data center as if they were part of the Azure platform. You will learn how to benefit from the centralized management that Azure provides, the automated rollout of patches and updates, and more.

This book is the perfect choice for anyone looking for a hybrid or multi-vendor cloud strategy for their data estate. The authors walk you through the possibilities and requirements to get services such as Azure SQL Managed Instance and PostgresSQL HyperScale, deployed outside of Azure, so the services are accessible to companies that cannot move to the cloud or do not want to use the Microsoft cloud exclusively. The technology described in this book will be especially useful to those required to keep sensitive services, such as medical databases, away from the public cloud, but who still want to benefit from the Azure cloud and the centralized management and tooling that it supports.

SQL Server on Azure Virtual Machines: A hands-on guide to provisioning Microsoft SQL Server on Azure VMs

Deploying SQL Server on Azure virtual machines allows you to work on full versions of SQL Server in the cloud without having to maintain on-premises hardware. The book begins by introducing you to the SQL portfolio in Azure and takes you through SQL Server IaaS scenarios, before explaining the factors that you need to consider while choosing an OS for SQL Server in Azure VMs. As you progress through the book, you’ll explore different VM options and deployment choices for IaaS and understand platform availability, migration tools, and best practices in Azure. In later chapters, you’ll learn how to configure storage to achieve optimized performance. Finally, you’ll get to grips with the concept of Azure Hybrid Benefit and find out how you can use it to maximize the value of your existing on-premises SQL Server

The PowerShell Conference Book

This book is designed to be like a conference in a book where each chapter is written by a different author who is a subject matter expert on the topic covered in their chapter. Each chapter is also independent of the others so you can read one chapter, ten chapters, or all of them. You can start with the first chapter, the last one, or somewhere in-between and not miss out on anything related to that particular topic. This bookis written for the intermediate to advanced audience. Prior experience with PowerShell is highly recommended. All (100%) of the royalties from this book are donated to the OnRamp scholarship program. More information about the OnRamp track at the PowerShell + DevOps Global Summit and their scholarship program can be found on the PowerShell.org website.

Optimizing Memory Access on GPUs using Morton Order Indexing

High performance computing environments are not freely available to every scientist or programmer. However, massively parallel computational devices are available in nearly every workstation class computer and laptop sold today. The programmable GPU gives immense computational power to a user in a standard office environment; however, programming a GPU to function efficiently is not a trivial task. An issue of primary concern is memory latency, if not managed properly it can cost the GPU in performance resulting in increased runtimes waiting for data. In this paper we describe an optimization of memory access methods on GPUs using Morton order indexing, sometimes referred to as Z-order index.

Toward Dependency-Aware Live Virtual Machine Migration

This paper proposes a novel dependency-aware approach to live virtual machine migration and presents the results of the initial investigation into its ability to reduce migration latency and overhead. The approach uses a tainting mechanism originally developed as an intrusion detection mechanism. Dependency information is used to distinguish processes that create direct or indirect external dependencies during live migration. It is shown that the live migration process can be significantly streamlined by selectively apply- ing a more efficient protocol when migrating processes that do not create external dependencies during migration.
