<strong>Exceed</strong> <strong>onDemand</strong> Deployment Wizard Explained<br />
Web-Deployed vs. CD-Installed<br />
> <strong>Exceed</strong> <strong>onDemand</strong> 5 — A <strong>Technical</strong> <strong>Whitepaper</strong><br />
<strong>Exceed</strong> <strong>onDemand</strong> Client can be deployed in two different fashions: traditional CD installation and<br />
Web deployment. CD installation is when users install <strong>Exceed</strong> <strong>onDemand</strong> Client directly from a CD<br />
or from the setup program that administrators distribute. This type of installation requires users to<br />
interact with the setup program. Web-deployment means the application is deployed from a web<br />
browser. User interaction is either not required or minimal. Often, CD-Installed software has more<br />
features than its web-deployed counterpart but that is not true in the case of <strong>Exceed</strong> <strong>onDemand</strong>.<br />
Regardless of the deployment method that is chosen, the same <strong>Exceed</strong> <strong>onDemand</strong> Client is installed<br />
on the user’s desktop, with the same features and functionalities. Administrators do not have to train<br />
users for different clients because there is only one client available.<br />
Download Mechanisms<br />
Connecting to a host simply requires the user to click on the URL the administrator provides. On the<br />
first connection to the web server, the user is prompted to accept the Hummingbird certificate, which<br />
assesses the integrity of the components that will be downloaded to the browser. This certificate<br />
prompt appears only on the first connection to the web server.<br />
After the certificate has been accepted, <strong>Exceed</strong> <strong>onDemand</strong> Deployment Wizard downloads the first set<br />
of components to the browser. This initial download usually takes less than 5 seconds on a regular 10<br />
MB Ethernet network. The only factors that can affect the size of the initial download are the number<br />
of languages supported, and the encryption level. A web deployment package that contains a strong<br />
encryption <strong>Exceed</strong> <strong>onDemand</strong> Client and single language file is slightly larger than 1 MB.<br />
In order to prevent unnecessary downloads, <strong>Exceed</strong> <strong>onDemand</strong> Deployment Wizard uses a technology<br />
called “Feature-on-Demand.” <strong>Exceed</strong> <strong>onDemand</strong> Deployment Wizard will only download the minimum<br />
set of components required to establish a connection to the host. All other features of the solution are<br />
packaged separately in small files that are only downloaded when the user invokes a specific function<br />
for the first time.<br />
For instance, the help files will never be downloaded to the user’s PC unless the user accesses the<br />
Help menu. Also, the Configuration Managers are not included as part of the initial download.<br />
