Book Description

XenApp 6 is the leader in application hosting and virtualization delivery, allowing users from different platforms such Windows, Mac, Linux, and mobile devices to connect to their business applications. It reduces resources and costs for application distribution and management. Using Citrix XenApp 6, you can deploy secure applications quickly to thousands of users.

Getting Started with Citrix XenApp 6 provides comprehensive details on how to design, implement, and maintain Citrix farms based on XenApp 6. Additionally, you will learn to use management tools and scripts for daily tasks such as managing servers, published resources, printers, and connections.

Getting Started with Citrix XenApp 6 starts by introducing the basics of XenApp such as installing servers and configuring components, and then teaches you how to publish applications and resources on the client device before moving on to configuring content redirection. Author Guillermo Musumeci includes a use case throughout the book to explain advanced topics like creating management scripts and deploying and optimizing XenApp for Citrix XenServer, VMware ESX, and Microsoft Hyper-V virtual machines. It will guide you through an unattended installation of XenApp and components on physical servers. By the end of this book you will have enough knowledge to successfully design and manage your own XenApp 6 Farms.

A complete guide to managing a virtualized application environment using XenApp.

Book Description

Xen, the open source virtualization tool, is a system administrator’s dream. Xen is a free, high-performance virtual machine monitor that lets you consolidate your hardware and finally put those unused cycles to use—without sacrificing reliability, performance, or scalability.

The Book of Xen explains everything you need to know in order to use Xen effectively, including installation, networking, memory management, and virtualized storage. You’ll also learn how to use Xen and standard Linux tools to take snapshot backups, perform QoS operations on network traffic, and limit over-aggressive disk users.

Authors Chris Takemura and Luke S. Crawford show you how to:
* Provide virtual hosting for dozens of users, each with their own individual needs
* Install and manage multiple guests, including various flavors of Linux, NetBSD, Solaris, and Windows
* Choose the right virtual storage options for your needs
* Migrate your systems seamlessly and create new images
* Tune and benchmark your systems to make them as fast as possible
* Troubleshoot Xen’s most common problems like network and memory management

Book Description

If you’re an experienced system administrator looking to acquire Linux skills, or a seasoned Linux user facing a new challenge, Linux System Administration offers practical knowledge for managing a complete range of Linux systems and servers. The book summarizes the steps you need to build everything from standalone SOHO hubs, web servers, and LAN servers to load-balanced clusters and servers consolidated through virtualization. Along the way, you’ll learn about all of the tools you need to set up and maintain these working environments.Linux is now a standard corporate platform with users numbering in the hundreds of millions, and there is a definite shortage of talented administrators. Linux System Administration is ideal as an introduction to Linux for Unix veterans, MCSEs, and mainframe administrators, and as an advanced (and refresher) guide for existing Linux administrators who will want to jump into the middle of the book. Inside, you’ll learn how to: Set up a stand-alone Linux server Install, configure, maintain, and troubleshoot a DNS server using BIND Build an Internet server to manage sites, perform email and file transfers, and more Set up an email service for a small-to-medium-sized site, complete with authentication Install and configure Apache, PHP, and MySQL on a web server built from scratch Combine computers into a load-balanced Apache web server cluster based on the free Linux Virtual Server Set up local network services from distributed file systems to DHCP services, gateway services, print services, user management and more Use Linux virtualization with Xen or VMWare to run multiple kernels on one piece of hardware; manage each kernel’s access to processortime, devices, and memory Create shell scripts and adapt them for your own needs Back up and restore data with rsync, tar, cdrecord, Amanda, and MySQL tools Linux System Administration is not only knowledgeable and practical, but convenient. The ingredients for this book had been scattered throughout mailing lists, forums, and discussion groups, as well as books, periodicals, and the experiences of colleagues. Everything is now in one handy guide. In the course of their research, the authors also solved many problems whose solutions were completely undocumented. They now pass their lessons on to you.

Book Description

What are the ingredients of robust, elegant, flexible, and maintainable software architecture? Beautiful Architecture answers this question through a collection of intriguing essays from more than a dozen of today’s leading software designers and architects. In each essay, contributors present a notable software architecture, and analyze what makes it innovative and ideal for its purpose.

Some of the engineers in this book reveal how they developed a specific project, including decisions they faced and tradeoffs they made. Others take a step back to investigate how certain architectural aspects have influenced computing as a whole. With this book, you’ll discover:

• How Facebook’s architecture is the basis for a data-centric application ecosystem
• The effect of Xen’s well-designed architecture on the way operating systems evolve
• How community processes within the KDE project help software architectures evolve from rough sketches to beautiful systems
• How creeping featurism has helped GNU Emacs gain unanticipated functionality
• The magic behind the Jikes RVM self-optimizable, self-hosting runtime
• Design choices and building blocks that made Tandem the choice platform in high-availability environments for over two decades
• Differences and similarities between object-oriented and functional architectural views
• How architectures can affect the software’s evolution and the developers’ engagement
