Puppet is a configuration management tool. It allows you to automate all your IT configurations by giving you control of what you do to each “node” (Puppet agent), focusing also on when and how you do it. In context, Puppet is a cross-platform tool that is widely used for Unix-like and Microsoft Windows systems declaratively. However, it has been used more popularly for Unix-like systems. This book provides insights into using Puppet for Windows administration tasks such as server setup, application updates, and service management.This book kicks off with the fundamentals of Puppet by helping you with the installation of Puppet on a Windows server and progresses with the introduction of the Foreman interface for managing Puppet nodes. Next, you deal with the installation of Puppet agents on multiple clients and how to connect them to your Puppet server by grouping your nodes for easy management. You then become familiarized with the scripting of Puppet manifests along with an understanding of the module structure in Puppet. You further move on to the installation of Puppet Forge Modules and their usage in Windows along with advanced topics such as facts, functions and templates.Moreover, you also venture into the security aspects for Windows by gaining insights into various security settings that will make your server and clients more secure from hackers using different attack vectors. You will also use Puppet and Chocolatey to install and update software.You finally round off by learning how to check the details of reporting and status monitoring along with the automation of installing and updating software for multiple Windows clients arming you with ample artillery to tame Puppet for your future projects.
Managing Mission - Critical Domains and DNS. Demystifying nameservers, DNS, and domain names
Mark E.Jeftovic
Managing your organization's naming architecture and mitigating risks within complex naming environments is very important. This book will go beyond looking at “how to run a name server” or “how to DNSSEC sign a domain”, Managing Mission Critical Domains & DNS looks across the entire spectrum of naming; from external factors that exert influence on your domains to all the internal factors to consider when operating your DNS. The readers are taken on a comprehensive guided tour through the world of naming: from understanding the role of registrars and how they interact with registries, to what exactly is it that ICANN does anyway? Once the prerequisite knowledge of the domain name ecosystem is acquired, the readers are taken through all aspects of DNS operations. Whether your organization operates its own nameservers or utilizes an outsourced vendor, or both, we examine the complex web of interlocking factors that must be taken into account but are too frequently overlooked. By the end of this book, our readers will have an end to end to understanding of all the aspects covered in DNS name servers.

SaltStack is known as a popular configuration management system, but that barely scratches the surface. It is, in fact, a powerful automation suite, which is designed not only to help you manage your servers, but to help them manage themselves. SaltStack is used worldwide by organizations ranging from just a few servers, to tens of thousands of nodes across data centers in multiple continents. This award-winning software is fast becoming the standard for systems management in the cloud world.This book will take you through the advanced features of SaltStack, bringing forward capabilities that will help you excel in the management of your servers.You will be taken through the the mind of the modern systems engineer, and discover how they use Salt to manage their infrastructures, and why those design decisions are so important. The inner workings of Salt will be explored, so that as you advance your knowledge of Salt, you will be able to swim with the current, rather than against it.Various subsystems of Salt are explained in detail, including Salt SSH, Salt Cloud, and external pillars, filesystems, and job caches.You will be taken through an in-depth discussion of how to effectively scale Salt to manage thousands of machines, and how to troubleshoot issues when things don't go exactly the way you expect them to.You will also be taken through an overview of RAET, Salt's new transport protocol, and given an insight into how this technology improves Salt, and the possibilities that it brings with it.
