Virtual Servers<br />
On <strong>Access</strong> <strong>Gateway</strong>, one needs to set up vServers (virtual servers) to act as logon<br />
points for all incoming remote connections. Such vServers can be set up in two<br />
modes:<br />
• Basic Mode<br />
• Smart <strong>Access</strong> Mode<br />
Basic Mode vServer<br />
A basic mode vServer is a server that consumes platform licenses and hence can<br />
be used to provide ICAProxy access to your XenApp / XenDesktop deployments,<br />
both via Web Interface and Storefront. A basic mode vServer essentially works<br />
out of the box, without the need to purchase any additional licenses. Once the<br />
platform licenses are consumed, this vServer can start consuming Universal<br />
licenses, if available. This leads to increased concurrent user support, which can<br />
go beyond the default that the appliance ships with.<br />
Smart <strong>Access</strong> mode vServer<br />
A smart access mode vServer essentially consumes Universal licenses and can be<br />
used to provide access to any <strong>Citrix</strong> deployment. Including XenApp / XenDesktop<br />
/ Cloud<strong>Gateway</strong>. Hence one can set up such a vServer only if additional Universal<br />
licenses are purchased, or are received as a bundles offering with Cloud<strong>Gateway</strong><br />
Enterprise / Xen Desktop platinum offerings. Note that a Smart <strong>Access</strong> vServer<br />
can only consume Universal licenses and will start dropping connections, once<br />
all universal licenses are consumed.<br />
Both these vServers can be set up using the new Simplified wizard that has been<br />
built into the latest <strong>Access</strong> <strong>Gateway</strong> offerings. This new wizard dramatically<br />
simplifies setting up of such vServers and automates the process of integrating<br />
this into your existing <strong>Citrix</strong> infrastructure. This wizard auto sets up all the<br />
required policies on <strong>Access</strong> <strong>Gateway</strong> to provide authentication and integrate<br />
with other <strong>Citrix</strong> products. More details on these policies can be found on my<br />
earlier blog available at -<strong>‐</strong> http://blogs.citrix.com/2012/08/06/whats-<strong>‐</strong>new-<strong>‐</strong>with-<strong>‐</strong><br />

Scenario<br />
Lets take an example scenario of how a <strong>Citrix</strong> deployment would look like and<br />
how <strong>Access</strong> <strong>Gateway</strong> can be best used in such a scenario, to provide seamless<br />
access to apps and desktops.<br />
Lets take a customer who needs to provide:<br />
1. 3000 users with access to their essential applications<br />
2. 1000 users with access to a full blown desktop<br />
3. 1000 users who need access to their web/saas/native mobile apps on the<br />
move<br />
In order to support the above scenario, lets say the customer procures:<br />
1. 3000 XenApp Enterprise licenses<br />
2. 1000 XenDesktop Platinum licenses<br />
3. 1000 Cloud<strong>Gateway</strong> Enterprise licenses
