A well-designed, feature rich VDI solution can make a significant difference in maximizing datacenter resources efficiency, and minimizing unwanted downtime. Failure to do both these things can drive up per user costs and affect user satisfaction. VMware Horizon View 5.2 reclaimed 27 percent of its previously used disk space from its virtual desktop, ran more efficient AV scans, and when deploying VMs, the VMware solution was faster than the Citrix solution by 38 percent. If your business needs to manage the time and resource burdens created by a VDI user base, VMware Horizon View 5.2 on VMware vSphere 5.1 provides strong advantages over Citrix XenDesktop 7 hosted on Citrix XenServer 6.2.

Infrastructure-As-Code means that infrastructure should be treated as code – a really powerful concept. Server configuration, packages installed, relationships with other servers, etc. should be modeled with code to be automated and have a predictable outcome, removing manual steps prone to errors. That doesn’t sound bad, does it?
The goal is to automate all the infrastructure tasks programmatically. In an ideal world you should be able to start new servers, configure them, and, more importantly, be able to repeat it over and over again, in a reproducible way, automatically, by using tools and APIs.
Have you ever had to upgrade a server without knowing whether the upgrade was going to succeed or not for your application? Are the security updates going to affect your application? There are so many system factors that can indirectly cause a failure in your application, such as different kernel versions, distributions, or packages.
When allegations against the Foxconn manufacturing plant—where Apple, Samsung, and Microsoft make large portions of their electronics—were first leveled in 2012, American consumers sure did seem angry. We were irate that their 1 million workers were grossly underpaid (or sometimes not paid at all), that 14-year-olds were making iPhones and Xboxes, and that the factory actually responded to people defenestrating themselves—seeking death rather than more work—by installing safety nets. As is so often the case, anger is all we could muster.

Storage giants NetApp (NASDAQ:NTAP) and EMC (NYSE:EMC) are making efforts to shift away from the tag of pure “storage companies”. In its Q2 earnings call last year, NetApp management pointed out that they are more of a “data management” vendor and not just a storage hardware company. [1] This statement signaled the company’s intention to evolve from being predominantly a hardware manufacturer to an end-to-end storage solution provider. A similar trend was highlighted when NetApp announced its agreement with VMware (NYSE:VMW) to integrate its Clustered ONTAP Drive with VMware’s vCloud suite last year. [2]
If we don’t balance the human values that we care about with the compelling uses of big data, our society risks abandoning them for the sake of mere innovation or expediency.
Ben Torres/Bloomberg via Getty Images
These days, everyone seems to be talking about “big data.” Engineers, researchers, lawyers, executives and self-trackers all tout the surprising insights they can get from applying math to large data sets. The rhetoric of big data is often overblown, exaggerated and contradictory, but there’s an element of truth to the claim that data science is helping us to know more about our world, our society and ourselves.
Data scientists use big data to deliver personalized ads to Internet users, to make better spell checkers and search engines, to predict weather patterns, perform medical research, learn about customers, set prices and plan traffic flow patterns. Big data can also fight crime, whether through the use of automated license-plate readers or, at least theoretically, through the collection of vast amounts of “metadata” about our communications and associations by the National Security Agency.
In a world where the Internet of Things (IoT) produces massive amounts of data from mobile devices, vehicular systems and environmental sensors, data scientist will be tasked with what to do with all of this information. We sat down with Cristian Borcea, PhD from the New Jersey Institute of Technology to discuss the IoT and Big Data applications.
insideBIGDATA: It seems we can’t turn on the television or read a newspaper without encountering the phrase, the “Internet of Things”. Aside from being a marketing term, what does this really mean?

Printing is a basic business requirement. Yet many of us do not have the capability to print from anywhere using any device as situation demands. Many IT departments are still struggling with the complexities of printer driver management.
Meanwhile, virtualization and cloud computing, mobile work style and BOYD trends add more challenges to enterprise printing, and brings security and compliance issues to the top of the agenda for C-level executives. Print security is much more than protecting gigabytes in a sealed room. Consider the risks of security breaches and potential damages when a sensitive document is printed and left unattended on a shared printer in a public environment. Forward-thinking organizations must future-proof their printing environments to provide worry-free printing with security and compliance at reduced costs.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

About this
design guide
The Citrix Design Guide provides
an overview of the XenDesktop 7
on Azure solution architecture and
implementation. This design has
been created through architectural
design best practices obtained
from Citrix Consulting Services
and thorough lab testing, and
is intended to provide guidance
for solution evaluation and the
introduction of proof of concepts.
The Design Guide incorporates
generally available products into the
design, and employs repeatable
processes for the deployment,
operation, and management of
components within the solution.

3. XenDesktop 7 on Windows Azure
Design Guide
With the introduction of Azure support for Remote
Desktop Services Subscriber Access Licenses (RDS
SALs) a broad set of opportunities to leverage Azure
for hosted Windows desktops and applications begin
to unfold. As a platform Microsoft Azure provides
a robust, state of the art infrastructure and global
presence for enterprises and service providers.
Citrix customers wanting to leverage public cloud infrastructure as a service in
order to expand their on premise datacenter capabilities, without investing in new
capital resources, can now host virtual desktops based on XenDesktop 7 within
Azure. This capability enables faster proof of concept and pilot builds for migration
to XenDesktop 7 for existing XenDesktop implementations, or as part of a new
XenDesktop implementation where the leverage of public cloud infrastructure
is preferred.
This document provides high level design guidance using a sample implementation
of XenDesktop 7 within the Microsoft Windows Azure cloud. Used in conjunction
with the XenDesktop Modular Reference Architecture these documents provide
basic best practice guidance for companies looking to leverage Citrix and
Microsoft cloud technologies to deliver a state of the art solution for their users.
Use Case
Let’s assume “World-wide Co, Inc.” (WWCo) plans to leverage Microsoft and Citrix
products to deliver a hosted desktop solution for their accounting department.
The solution will provide value to the department by enabling access to Windows
desktops and applications from any device. The value of this solution for Worldwide Co. is most evident in the ability to quickly bring new desktop services on
line through a subscription to Azure infrastructure services rather than a protracted
capital investment and datacenter build out project. Since the new desktops are
an extension of the existing World-wide Co datacenter, the infrastructure already
in place at World-wide Co. will be connected to Azure through a Site-to-Site VPN.
This connectivity enables the Azure hosted XenDesktops to communicate with
World-wide Co. corporate Active Directory and Back-office services like Microsoft
Exchange or Microsoft Lync, as well as the corporate Secure Remote Access
services Enabled through Citrix NetScaler Gateway.
The objective of this guide is to outline World-wide Co. business considerations,
and how hosting their new XenDesktop 7 workloads in Azure could address them.
Business Objectives
• Provide secure access to desktops and applications for the accounting team
• Avoid the need to build new infrastructure within the WWCo datacenter
citrix.com

4. XenDesktop 7 on Windows Azure
Design Guide
• Leverage as much existing corporate infrastructure as possible to align with
current IT practices and policies and to keep new expenses as low as possible
• Use monthly programmatic funding instead of capital expenses for this project
• Manage the service within a public cloud environment in order to scale based on
seasonal resource requirements
• Provide support for any device, enabling temporary contractors to “Bring your
own Device”
Technical Objectives
• Quickly design and implement environment to establish the value and metrics
• Ensure high availability of critical components to ensure business continuity
• Implement an “n+1” highly available solution to avoid any business interruption
• Support access from user-owned devices that vary in form factor and
operating system
Citrix XenDesktop 7 on Azure
World-wide Co. selected XenDesktop as their solution since they enable the
best user experience across the public internet from any device according
to independent analysis, and after reviewing the Citrix XenDesktop Modular
Reference Architecture and Microsoft’s Windows Azure IaaS capabilities, they
believed they could build a solution without a large upfront capital investment.
The Citrix XenDesktop 7 solution hosted on Azure consisted of a small number
of components.
Citrix XenDesktop 7 Delivery controllers
• Hosted Shared workers (Session Isolation)
• and Server VDI Workers (VM/Server Isolation)
• An Azure local Active Directory DC that is a member of the World-wide Co.
Corporate Forest
• An Azure local SQL Server VM Instance
• An Azure local File Server for the storage of XenDesktop Roaming User Profiles

• Server VDI Workers – These XenDesktop 7 workloads provide VM or Server
level isolation of an individual VDI desktop for those users that require more
customization or administrative control of their virtual desktop.
• Citrix License Server – The Citrix License Server hosts all of the licenses that
enable Citrix products and features.
• NetScaler Gateway – NetScaler Gateway is a secure application and data
access solution that provides administrators granular application- and data-level
control while empowering users with remote access from anywhere.
• StoreFront Services – StoreFront Services provides authentication and
resource delivery services for Citrix Receiver, enabling you to create centralized
enterprise stores to deliver desktops, applications, and other resources to users
on any device, anywhere.

XenDesktop 7 on Azure Architecture
Once World-wide Co. had completed their assessment and concluded that a
Citrix XenDesktop 7 solution on Microsoft Azure could meet their objectives, they
quickly moved into the design phase. World-wide Co. wanted a simple, easy
process to determine the hardware and storage sizing to support their individual
implementation based on the needs of their subscribers. World-wide Co. used
Citrix Project Accelerator-an open, web-based application where you can manage
your move to virtualized desktops and applications based on best practices of
Citrix’s top consultants - to assist with the user assessment and environment
design. In conjunction with project accelerator guidance, World-wide Co. made the
following design decisions:
• Although Project Accelerator was currently designed for XenApp 6.5 and
XenDesktop 5.6 versions of the Citrix products, World-wide Co. decided that
its output could be used as a foundational design to work from in conjunction
with their own testing to determine the final requirements when they went
to production.
• For a robust solution high availability is important, so an “N+1” configuration was
chosen to ensure that the solution sizing included a spare server to handle user
capacity in the event of a failure.
• All users would need to connect to Azure over an encrypted connection through
a Site-to-Site VPN between Azure and the World-wide Co. corporate network.
Secure remote access would be provided by NetScaler Gateways within the
corporate network.
• Active Directory, DNS/DHCP, and SQL Server would be provisioned in Azure to
reduce login times for this solution.
• A variety of financial applications, as well as MS Office would be made available
as part of the standard desktop image for this group of users.
The following architecture is a visual representation of the solution as
recommended by Citrix Project Accelerator. Additional considerations that leverage
this output as the base are documented later in this guide. The following diagram
represents World-wide Co.’s projected hardware, and infrastructure requirements
based on a team of 100 users, spread over the 2 types of users; task workers and
content creators.

Access layer
The access layer consists of the servers responsible for providing connectivity to
the XenDesktop 7 on Azure environment.
Figure 3: Access layer
WWCO’s solution required the following Citrix components to provide secure
remote access
• StoreFront Services – StoreFront Services provides a self-service subscription
service to desktops and applications via an enterprise app store, giving users
convenient access to all the resources they need. WWCO created a centralized
enterprise app store with StoreFront Services within their on premise datacenter
to enumerate and aggregate the resources available for each user. WWCO
deployed a pair of StoreFront servers to ensure high availability.

• NetScaler Gateway – NetScaler Gateway is a secure application and
data access solution that gives administrators granular application and data|level control while empowering users with remote access from anywhere.
IT administrators gain a single point of management for controlling access
and limiting actions within sessions based on user identity and the endpoint
device. The results are better application security, data protection and
compliance management.
NetScaler Gateway works in conjunction with StoreFront Services to authenticate
the user and create an SSL tunnel between the end-user and NetScaler Gateway
to ensure secure remote access from any device. NetScaler Gateway requires
either a physical or virtual NetScaler appliance. WWCO selected two physical
NetScaler MPX appliances to host NetScaler Gateway in an active/active mode to
ensure secure access is highly available and maximum capacity.

Desktop layer
The Desktop layer represents the separate use cases that WWCO will service. As
you can see, plans for 95 users to access Task Worker resources, and 5 users to
access Content Creator resources.
Figure 4: Desktop layer
The WWCO solution required the following Citrix components to provide the
Desktop Layer,
• Citrix XenDesktop Delivery Controllers – These XenDesktop 7 Servers are
used to manage and deliver dedicated the Windows applications and desktops.
• Hosted Shared Workers – These XenDesktop 7 servers are used to deliver
shared hosted applications and desktops for most users.
• Server VDI Workers – These XenDesktop 7 workloads provide VM or Server
level isolation of an individual VDI desktop for those users that require more
customization or administrative control of their virtual desktop.

Management and operations
For day to day administration Desktop Director was leveraged to manage and
support the environment. Support staff and administrators were granted access to
the console.
Administrators manage the site using Desktop Studio. This console handles all
site level responsibilities including policies, device and user allocations. Only
senior administrators are granted access to the Desktop Studio. The console was
installed on each XenDesktop controller for high availability.
Additional tools are available to support managing the environment:
The Project Accelerator outputs provide the base sizing and architecture for
AzureCSP’s CSP on Azure solution. The following sections provide additional
considerations, tools and optimizations specific to CSP multi-tenancy and the
Azure IaaS platform itself. Taken into consideration together a complete solution
was implemented in Azure.
Solution capabilities and constraints
Project accelerator architecture modifications within Azure
The following sections outline some of the considerations within Azure that have
influenced this design beyond the recommendations from the Project Accelerator.
Azure as an IaaS platform
The Azure platform has evolved to include several Infrastructure as a Service
enabling technologies. This section provides a brief overview of those technologies
that are leveraged as a part of the Citrix solution on Azure.
More information about Azure IaaS and Windows VM Instance capabilities can be
found at http://www.windowsazure.com/en-us/manage/windows/.
Networking
Windows Azure Virtual Networking enables a secure environment for each Azure
tenant. The example in this guide uses a single virtual network for all Azure hosted
XenDesktop 7 workloads. An Azure Site-to-Site VPN connection was used
between WWCO’s on premise corporate datacenter and the Azure hosted
virtual network.
More information regarding Azure Networking can be found at http://www.
windowsazure.com/en-us/manage/services/networking/.
Storage
The scenario in this document leverages Azure shared storage as provided to the
VM instances provisioned within Azure. In addition a Windows Server 2012 File
Server has been configured within Azure as a shared file service for the storage of
user profiles and data. Additional storage can be allocated within the environment
as required for other workloads not documented in this guide.
citrix.com
14
15. XenDesktop 7 on Windows Azure
Design Guide
More information about Azure storage can be found at http://www.windowsazure.
com/en-us/manage/services/storage/.
Important!: Due to the fact that Citrix Provisioning Service is not supported
with Azure at this time the storage calculations from the Project Accelerator can
differ significantly from the storage actually used. Please confirm your storage
requirements as part of your cost models.
Provisioning
The provisioning of VM Instances within Azure is accomplished through manual
creation of the instances through the Azure portal. Larger scale environments
can be provisioned using Azure PowerShell scripting. The appendix of this guide
provides some sample scripts used to provision various instances and workloads
within Azure. The portal UI examples in this guide are used for the sake of clarity,
while it is generally recommended that a CSP leverage the Azure PowerShell scripts
to ensure continuity when provisioning instances over time or at larger scale.
More information about Azure PowerShell and other command line tools can be
found at http://www.windowsazure.com/en-us/downloads/#cmd-line-tools.
Secure access
For the scenario in this guide, secure access to desktops and applications within
Azure is provided through the WWCO on premise NetScaler Gateway when
connecting to Azure hosted workloads. The connections made through the
NetScaler Gateway are then passed through the Azure Site-to-Site VPN to the
Azure hosted desktops and applications.

This same basic procedure can be followed to provision all of the VM instances
required for the environment. As an AD controller you will next need to install the
AD roles for your environment.

PowerShell can be found at http://www.windowsazure.com/en-us/manage/
services/networking/active-directory-forest/.
Once the provisioning of a VM has finished you will see the instance in a running
state. A screen shot of the complete set of VM instances provisioned in Azure for
this sample design demonstrates the state of these VMs.

25. XenDesktop 7 on Windows Azure
Design Guide
Once the networking and VM instances are in place the standard XenDesktop
installation procedures as outlined in the product documentation were followed.
There are no special considerations when implementing XenDesktop delivery
controllers or worker servers within Azure as proposed in this sample design.
A few suggestions for securing Azure IAAS VM instances
• Rename the local administrator account.
• Disable the local administrator account and create some uncommonly named
user account for administrative access.
• Choose strong plus complex passwords, or passphrases. Not simply one or the
other. The OS can enforce complexity but not strength.
• A dictionary attack is likely to hit “P@ssw0rd” but it is unlikely to hit “Just a city
boy, born and raised in South Detroit”.
• Denying user access after X failed logon attempts (lock the account). This is a
Local security policy if not domain joined, or a Domain policy if joined. Consider
an automatic (timed) unlock as well, or you could have no recourse but to
destroy your machine.
• Do not allow the creation of the default RDP public endpoint. This is only
possible through the API / PowerShell. Or delete the auto created endpoint after
creating the machine in the Portal.
• Only create the RDP endpoint when remote administration is necessary, and
removing it after. But remember that we are human, and unless you have some
interface doing this for you, you will probably forget at some point.
citrix.com
25
26. XenDesktop 7 on Windows Azure
Design Guide
• Remove the RDP endpoint and use the Virtual Network Gateway feature of
the Azure Virtual Network for secured remote administration without public
endpoints. This requires some ground based router, and the VPN is slow, but
your ports are closed.
• Remove RDP endpoint & use Azure Connect. This is limited to IPv6 TCP traffic
only, but that should cover anything required to manage the OS.
• Avoid 3389 as the public port (I noticed my compromised machine specifically
scanning for this port to spread itself) by using a port in the ephemeral range.
• Use the Windows Advanced Firewall rules and define them appropriately.
• Use Windows IP Security Policies and tightly define the sources from which RDP
traffic can be accepted from. This is highly effective, but a pain to set up.
• Monitor the machine. Azure provides metrics through the portal and API.
Discover a baseline. Use an agent within the machine. This only detects the
compromise after it happens and is not preventative.
• Take a snapshot of the clean state. This is not a point and click thing in Azure
today, but you can work this out using the Storage cmdlets through destroying
your machine, making the diff disk, and reincarnating the machine.
Conclusion
By cross referencing the Citrix Project Accelerator and XenDesktop Modular
Reference Architecture WWCO was able to implement a XenDesktop solution
within Microsoft’s Azure IaaS environment. Leveraging public cloud infrastructure
such as Azure virtually eliminated any need for a new WWCO capital investment,
allowing them to bring their new service online quickly in a globally available, state
of the art cloud hosted infrastructure.
By leveraging Citrix XenDesktop 7 WWCO was capable of providing an industry
leading desktop virtualization solution, ensuring the best user experience across
any device, in as enabled by Citrix technologies like HDX.

Appendix—Sample Azure powershell scripts
This section includes some basic information for using Azure PowerShell scripts to
build a Hosted Desktop environment within Azure. The “Basics” section provides
some of the useful cmdlets you will use to configure and discover resources within
your Azure subscription, the “Examples” section contains versions of scripts used
by Citrix in testing the published scenario.
Note: The Azure PowerShell cmdlets are a work in progress.
They are currently a community contribution that is being folded into the product
lifecycle and enhanced by MSFT and properly released.
You can find the cmdlets here:
https://www.windowsazure.com/en-us/manage/downloads/.
The primary information source on using the cmdlets is this blog:
http://michaelwasham.com/ (Azure Evangelist as MSFT).
Be sure to have your Azure management certificate properly stored in your
Personal certificate store prior to connecting to your subscription.
Basics:
Here are some useful commands to use the cmdlets to drive machine and
service creation.
These commands must be used to configure your Azure PowerShell session to
communicate with your specific Azure subscription.
Import the module
import-module ‘C:Program Files (x86)Microsoft SDKsWindows Azure
PowerShellAzureAzure.psd1’
Import a settings file (this speeds up as it lists all subscriptions you have access to)
to create this file perform
Export-AzurePublishSettingsFile (Visual Studio also uses this)
Then import the settings file into your environment
Import-AzurePublishSettingsFile ‘C:UsersPublicDocuments<your
subscription>-credentials.publishsettings’
Choose the subscription that you will interact with for your session
Select-AzureSubscription -SubscriptionName “<your subscription>”
Set the default Storage account that will be used (it must be in the same
subscription)

Useful cmdlets for Finding an Image from which to create Virtual
Machines
The filters can be changed to focus on Gallery images or images that have been
user created.
List all available images:
Get-AzureVMImage
List all available in a table:
Get-AzureVMImage | Format-Table
Find images that have been uploaded to your Storage account (‘user’ images):
Get-AzureVMImage | where { ($_.Category -eq “user”) }
Creating virtual machines from images
Note: by default a new service is created and the VM added, unless an existing
Service name is defined.
This same image will be used for both examples:
$svr2012Image = Get-AzureVMImage | where { ($_.Category -eq “Microsoft”)
-and ($_.Label -match “Server 2012” ) -and ($_.ImageName -match “Datacenter”) }
Apply a customization configuration to the image:
$myImage = New-AzureVMConfig -Name <Your Image Name> -InstanceSize
ExtraSmall -ImageName $svr2012Image.ImageName
Add-AzureProvisioningConfig -VM $myImage -Windows -Password P@ssw0rd
New-AzureVM -ServiceName “<Your Service Name>” –VMs $myImage
A more advanced configuration that also creates endpoints and sets a Virtual
Network, DNS Settings, Affinity Group, and creates a new IaaS service
$myImage = New-AzureVMConfig –Name <Your Image Name> -InstanceSize
ExtraSmall -ImageName $svr2012Image.ImageName
Add-AzureProvisioningConfig -VM $myImage -Windows -Password P@ssw0rd

Defining a custom DNS setting (for your DNS server, necessary for AD
domain join)
As seen above New-AzureDns created a configuration XML object that is applied
to a Virtual Network or to a Service when the first Virtual Machine is added. This
setting can only be added with the first Virtual Machine in the Service.
$dns = New-AzureDns -Name <Your Name> -IPAddress 10.104.2.4
New-AzureVM -ServiceName “<Your Name> “ –VMs $myImage -VNetName
VNetOne -DnsSettings $dns -AffinityGroup <Your Affinity Group Name>
Defining joining to an AD on provisioning
Here the -JoinDomain section is added to the Provisioning Configuration and
-WindowsDomain is used instead of -Windows

Examples
These are some script samples that were created to enable working through
scenarios with Azure Virtual Machines (IaaS). As the Azure platform continues
to evolve some cmdlets and parameters may change. Please work through
the Azure help and documentation to ensure your scripts provide you with the
correct configurations.
Creating XenApp infrastructure virtual machines using the July 2012

If the Gallery image has been updated, this will need to be modified to select
the proper one. This particular image is Server 2008 R2 SP1 Datacenter. Note
the hardcoded Virtual Network, Subnet, and Affinity Group settings; as well as

The assumption here is that Azure will name the OS of the VMs with the Machine
Name specified and join them to my Domain Control in Azure. The Domain Controller
is located through DNS, so you must provide your own DNS. This can be done by
adding the DNS on the new AD controllers to your Azure virtual network.
This script should create images that are ready for App Orchestration 1.0 to
provide the Citrix Hosted Desktop Services installation and configuration.
