Masterarbeit aus dem Jahr 2016 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,3, Friedrich-Schiller-Universität Jena, Sprache: Deutsch, Abstract: Wachsende Datenströme und die damit verbundene Herausforderung einer effizienten Verwaltung deuten darauf hin, dass auch Datenbankmanagementsysteme (DBMS) vor einer Revolution stehen. Tape is Dead, Disk is Tape, Flash is Disk, RAM Locality is King. So beschrieb Gray, Informatiker und Wissenschaftler bei Microsoft Research, die zunehmende Verschiebung der Speicherhierarchie. Haben traditionelle DBMS noch Sekundärspeicher unter entweder zeilen- oder spaltenorientierter Datenorganisation verwendet, gebrauchen In-Memory Datenbanken (IMDB) Hauptspeicher und eine primär spaltenorientierte Datenorganisation. Damit soll es in Echtzeit möglich sein zum einen große Datenmengen auswerten und zum anderen die Informationen zum Zeitpunkt des Entstehens verarbeiten zu können. Verhinderte in den Achtziger Jahren die starke Unzuverlässigkeit des Hauptspeichers und das hohe Preisniveau die Etablierung von IMDB, so ist es heute möglich den Einsatz in Datenbanken ökonomisch zu legitimieren.
Automate your workload and manage more databases and instances with greater ease and efficiency by combining metadata-driven automation with powerful tools like PowerShell and SQL Server Agent. Automate your new instance-builds and use monitoring to drive ongoing automation, with the help of an inventory database and a management data warehouse. The market has seen a trend towards there being a much smaller ratio of DBAs to SQL Server instances. Automation is the key to responding to this challenge and continuing to run a reliable database platform service. Expert Scripting and Automation for SQL Server DBAs guides you through the process of automating the maintenance of your SQL Server enterprise. Expert Scripting and Automation for SQL Server DBAs shows how to automate the SQL Server build processes, monitor multiple instances from a single location, and automate routine maintenance tasks throughout your environment. You will also learn how to create automated responses to common or time consuming break/fix scenarios. The book helps you become faster and better at what you do for a living, and thus more valuable in the job market. Extensive coverage of automation using PowerShell and T-SQL Detailed discussion and examples on metadata-driven automation Comprehensive coverage of automated responses to break/fix scenarios What You Will Learn Automate the SQL Server build process Create intelligent, metadata-drive routines Automate common maintenance tasks Create automated responses to common break/fix scenarios Monitor multiple instance from a central location Utilize T-SQL and PowerShell for administrative purposes Who This Book Is For Expert Scripting and Automation for SQL Server DBAs is a book for SQL Server database administrators responsible for managing increasingly large numbers of databases across their business enterprise.

This book is your hands-on guide to infrastructure provisioning and configuration management in the cloud using Chefs open source, cross-platform toolset. With over 10,000 customers joining the Microsoft Azure cloud platform each week and steadily increasing usage, the need for automation approaches has never been greater. This book provides both practical examples and a much needed strategic overview of how these two technologies can be combined. Using Chef with Microsoft Azure takes you through the process of writing recipes in Chef to describe your infrastructure as code, and simplify your configuration management processes. Youll also meet the Chef tools that can be used to provision complete environments within Microsoft Azure. There are now a wide variety of tools and approaches that can be taken to provision resources such as virtual machines within Microsoft Azure. This book demonstrates them, discusses the benefits and weaknesses of each approach, and shows how a continuous provisioning pipeline can be established as part of a reliable, repeatable, and robust provisioning process. Each chapter has practical exercises that highlight the capabilities of both Chef and Microsoft Azure from an automation perspective and can be executed on Windows, Mac, or Linux platforms. In this book, youll learn: The purpose and principles behind automated provisioning Microsoft Azure concepts and management options How to deploy Chef Azure Virtual Machine Extensions using PowerShell, Azure command-line tools, and Chef Provisioning Chef Provisioning techniques, including provisioning PaaS resources such as KeyVault How to integrate quality tooling into the Chef development lifecycle, including Test Kitchen and InSpec with Azure compute resources How to set up a pipeline for continuous provisioning with Chef and Azure Who This Book Is For This book is for infrastructure platform and operations engineers and DevOps specialists/practitioners working with infrastructure and platform provisioning on Microsofts public cloud, Azure. An understanding of programming in any language would be beneficial, but not necessary as the examples are designed to be easily readable by anyone with general IT experience. While it is expected most users picking up this book will be on the Windows platform, a good proportion of compute workload on the Azure platform is Linux based. As a result the book includes examples that are relevant to both Windows and Linux platforms.
