My preschooler expects her interaction with technology to be easy and uninterrupted regardless of location or device. Adults in the workforce want that same experience with technology they need to do their jobs. An office is just one of the places people work today. Citrix helps those people stay connected to the things and people they need to do their job, no matter where they are.
They have everything they need at their fingertips — saving them time, helping them be more productive, and making their jobs easier. Even if you leave the office and shut down your session, you start working again on the train, and the cursor is in the same position as you left it in the office. This is the future. This is how it should work. Diving a bit deeper, our solutions combine digital workspace and networking technologies to provide access to the things people need to get work done.
On the frontend, people have one place to safely access all their apps, desktops, files, and services from any of their devices and from any location.
And on the backend, IT has a simple, unified platform to manage, monitor, and oversee everything. What was once physical is now digital. What you once had to go into an office to do, you can now do anywhere with a Citrix digital workspace. It gives people access to all the apps they use for work — web, virtual, mobile, and SaaS — from one easy-to-use portal on any of their devices, from wherever they need to work. Also, since such a big part of work is making and sharing new documents, designs, and videos, Citrix Content Collaboration lets everyone in an organization easily store the things they make in a safe, shared place.

The XML broker functionality is provided in Pinklebury site by Emily, who can check with the site hand, Tony, to see what eggs are available. With a Citrix Virtual Apps Site, to keep tabs on what applications are available and who is allowed to use them, a database is used.
The database keeps detailed records about the applications including locations, who can use them and so on. This is sort of similar to Lisa's role, where the owner's youngest daughter keeps detailed records. Owner John needs a license to operate Pinklebury site from the Ministry of Agriculture and this license, allocates the maximum number of people owner John can provide eggs to.
Citrix Virtual Apps Sites need licenses too and these contain limits for the maximum number of users who can access the Citrix Virtual Apps Site. Citrix Virtual Apps Sites have an administrator, a user who has the required rights to change how the Citrix Virtual Apps Site is set up. Likewise, Pinklebury site has an administrator, owner John, who can also elect to change how the site is set up.
Administration tasks can be delegated to other users in a Citrix Virtual Apps Site by the main Administrator. Likewise, owner John can delegate his administration duties to his wife or he can hire new people to carry out specific or even all of his administration duties. Owner John can cater for more demand, by increasing the number of chicken coops or by buying another site and by taking on more site hands to handle the increased workload.
He can still use his shop to sell eggs from the new site but would need to take on a new person to keep detailed records for the new site. As it will be impossible for Lisa to do the record keeping work load of two sites. The Ministry will need to issue a new separate license for an agreed number of people who can be served eggs from the new site.
Likewise a new license will need to be obtained for the new Citrix Virtual Apps site and this can be set up on the existing Citrix License server. Likewise the Citrix Virtual Apps site administrator can create more zones and add more Citrix Virtual Apps servers into each zone to cater for more demand, as shown in the screenshots below.
The administrator can also create a separate Citrix Virtual Apps Site, as shown in the screenshot above. A separate Citrix Virtual Apps site can utilise the existing StoreFront as a shop front to the applications available from both Citrix Virtual Apps sites.
An additional separate database will be required to cater for the data storage requirements of the new Citrix Virtual Apps site. The analogy of how Pinklebury Site is managed should provide an easier understanding of how the key concepts in the world of Citrix Virtual Apps work.
By taking a look at the key concepts again technically, an understanding of how they work can be more clearly understood. This is a computer which hosts, that is, has the applications word processor, web browsers etc. The Citrix Virtual Apps software provides enhancements to Windows Server Operating System in terms of application delivery and management.
The Citrix Datastore just a database on a database server and a single database server can have several databases, acting as unique datastores for different Citrix Virtual Apps sites. For example, the screenshot below shows Citrix Virtual Apps Site databases on the same server. The datastore provides a permanent store for Citrix Virtual Apps site information until a time it is changed or removed.
The Data Collector holds an in memory database of Citrix Virtual Apps server information, monitoring their states and available capabilities. A web based front end where users log in and get presented with information about applications they are allowed to use. The StoreFront talks to an authentication service such as Microsoft Active Directory, to determine whether the user is allowed access to the Citrix Virtual Apps site via the StoreFront.
If the user is allowed access, the StoreFront then speaks to the XML broker and asks it for a list of applications the user is entitled to use. The icons images with shortcuts, as shown in the screenshot StoreFront displaying applications and folders below, are then displayed on the StoreFront web page.
When these icons are clicked they launch the remote control access to the applications on a particular Citrix Virtual Apps server.
The screenshot below show StoreFront displaying applications and folders. Each zone must have a Citrix Virtual Apps server configured as zone data collector. Whilst it is possible to separate Citrix Virtual Apps servers into separate sites, this would require increased administration and additional components in comparison to partitioning Citrix Virtual Apps servers into zones.
As stated in the StoreFront section, the XML broker is an intermediary for the StoreFront to find out which applications are available to the user. The XML broker is a program which runs on a server.
It is known as a service for two reasons, firstly it provides a service, that is brokering information and secondly, it carries on running on the server listening for requests from the StoreFront, even when there is no one logged on to the server. The term 'publishing' means presenting users with particular applications. So in the steps to publish an application, the administrator must define what the application is what it's called, where it's located and who can access it.
Published applications appear seamlessly on the user's desktop when accessed. This means they appear as though they are running on the user's desktop when in fact they are running on the Citrix Virtual Apps server.
Applications on the Citrix Virtual Apps server are still being accessed remotely by the user, but the user is being presented with the application, as if it's actually on their computer. Whilst publishing applications involves publishing individual applications, so they appear as though they are running on the user's desktop, publishing desktops, involves presenting the Citrix Virtual Apps servers desktop on the user's computer.
So the user sees what would be seen if they logged onto the Citrix Virtual Apps server directly, as shown in the screenshot below. Both publishing applications and desktops gives users remote access to applications and the Citrix Virtual Apps servers desktop respectively. Streaming applications involves sending the application to the user's desktop, to run on the user's computer.
Portions of the application which have been specially packaged are sent to the user's computer in sufficient amounts to ensure the application starts. All the grunt of the application is done on the user's computer, as opposed to published applications where the application processing is done on the Citrix Virtual Apps servers.
Previously known as Program Neighbourhood Agent PN Agent works a bit like the StoreFront but instead of displaying application icons on a web page in a portal, Citrix Virtual Apps Services actually displays the icons on the start menu of the user's computer, as shown by the Citrix Virtual Apps Services updated Start Menu screenshot below.
How does Citrix Virtual Desktops work? These are then managed by Citrix Virtual Desktops so different groups of Virtual PC's can be assigned to users to use. Citrix Receiver provides the technology to interact and display the information send from Citrix Virtuals Apps and Citrix Virtual Desktops on the user's device. What is Citrix and why is it on my computer? Citrix allows you access desktops and applications remotely with the look and feel the same as if they applications were installed on your computer.
The Citrix on your computer is a small piece of software called WorkSpace Receiver older name that allows the magic of connecting to application and desktops on Citrix servers to be displayed on your computer. This replaced the application isolation feature that was available in some previous versions of XenApp.
By profiling an application using the Citrix Streaming Profiler you can stream the application down to a target Operating Systems without having to install anything apart from the Citrix Offline Plug-in. With Application Streaming you have the option of streaming the application to the client device, or to a XenApp server. If you stream to a client device it will run locally on that device and consume local resources CPU, memory etc , if you stream to a XenApp server it will run on the XenApp server and be accessed over ICA just like a traditional XenApp server-installed application.
Streamed applications are cached on the target operating system and therefore only pulled across the network on first run or when the central package is updated. You install the Citrix client software once and then you can deploy pretty much any application to any machine without having to ever visit them again. Because all the processing is done on the XenApp servers you can deploy apps that would potentially not run on older desktops. If you are considering thin clients you can potentially run all of your users on XenApp and get rid of the maintenance costs associated with PC Operating Systems and hardware.
Citrix streamed applications execute locally on the target Operating System within a sandbox isolation environment. This means that the applications cannot interfere with or break other applications on the target Operating System. Streamed applications can be run offline on laptops for up to days.
