Getting Started with Citrix XenApp?? 7.6

Chapter 2. Designing a Citrix® Solution to Fit Your Needs

This is one of the most important chapters in this book. I say this because without proper planning and an assessment of requirements, implementation would imminently fail to meet your business needs, which could lead to financial losses to your company. To avoid this, sufficient time needs to be allocated to building a phased approach, starting with design. The following topics will be covered in this chapter:

  • Project planning
  • Reference architectures
  • Collecting data from existing systems
  • Defining boundaries and peripherals
  • Analyzing and testing core applications
  • Architecting Citrix XenApp and other components
  • Real-world examples from the field

Project planning

If you are reading this book with the intention of building an IT business solution for your company, then you are probably already involved in a project or some type of initiative with clear objectives and metrics in order to achieve success. Every successful IT project requires a great bit of attention to detail in planning and architecting a solution that would have a substantially positive impact on business operations. Many consulting companies take a phased approach when working with their client on projects. Usually, a project manager creates a project plan with a schedule chalked out to complete tasks or milestones. Projects can vary in terms of size and resources. On a very basic level, the lifespan of a project can consist of several phases:

  • Design
    • Conducting the analysis of an existing environment
    • Defining business requirements and limitations
    • Architecting an IT solution according to specifications
  • Implementation
    • Building a solution based on design specifications
    • Documenting...

Reference Architectures

A Reference Architecture (RA) is a technical document designed to showcase a software or hardware solution. RA very often serves as a template for standardized computer system deployments and is widely used by administrators and consultants to assess infrastructure requirements, perform benchmark testing, and obtain knowledge about product features. Typically, vendors release RA papers on a regular basis whenever a new version is released or a third party product is tested. For example, on their website, Cisco has an RA for a Citrix XenDesktop system built on UCS blade servers, Nexus switches, and VMware ESXi. Of course, this is only a basic foundation of a single configuration that has been tested by vendors, and actual systems deployed in the field will vary according to the business needs of the end customer. Most RAs contain a business scenario and a documented approach to accomplish this goal, including a proven combination of hardware and software and multiple...

Designing XenApp® for an enterprise

Now that you are familiar with what RA is and how a planned approach works, you will be able to design your own architecture that will fit the unique needs of your company. The real purpose of this chapter is to arm you with the right tools and guide you through the process to accomplish your goals. In this book, we'll build a solution from scratch, but whether this is true in your case or you are just looking to expand your existing environment, the best way to start is by setting a goal and defining what we know already.

Goals

It's your first day as a system admin. Your boss calls you in her office and tells you that due to high work volume, your training has been cancelled and you are being placed on a project. She says the CIO of the company has become increasingly concerned with recent security breaches in the industry and wants to prevent any sensitive data from leaving the corporate premise. He also insists on being able to manage...

Creating your first architecture

Now that you have conducted an assessment of all the relevant components in your existing environment, it is time to create your first architecture design. This will be composed of Citrix XenApp, StoreFront, Provisioning Services, XenServer, and NetScaler, and it will attempt to resemble real-world scenarios as closely as possible. Some components, such as NetScaler, are optional, albeit strongly recommended and will be marked as such throughout the book. So let's start with creating a description of the specifications of the environment. You can skip the next subsection on physical hardware if you already have a hypervisor in place.

The host hardware

To host hypervisors, you can use any enterprise servers that are certified by your hypervisor vendor. Citrix, VMware, and Microsoft have a Ready program that thoroughly tests and certifies hardware (visit http://www.citrix.com/, http://www.vmware.com/, or http://www.microsoft.com/ for more information)....

Examples from the IT field

Before we go ahead and conclude this chapter, I would like to provide some real-world examples from consulting projects that I've been heavily involved in, which demonstrate use cases for Citrix XenApp from the field.

  • A nationwide transportation company implemented hosted shared desktops via XenApp for its fleet division to use locally installed applications. Lock down policies were put in place to ensure that no administrative changes could be made by users to the shared desktop image.
  • A leading credit institution implemented hosted applications via XenApp for its teller workforce in branch locations in order to be able to work with legacy banking apps that are no longer supported in later OSes, such as Windows 7 and 8.
  • A major hospital in the Southeast U.S. implemented XenApp to host performance-intensive Electronic Medical Records (EMR) software. High-capacity XenApp servers were dedicated to an individual application that was published for end users (a method...

Although there is plenty of Citrix XenApp material on the web, this is one of the true start to finish, cover all the bases guides. We're currently migrating from 6.5 to 7.6 and this was the one resource I needed that covers and explains all the components and how they all fit together. Delivery Contollers, Store Front servers, Netscaler, PVS and MCS. It's all here.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
