Additional Installation Options

The next few sections describe CloudPlatform features above and beyond the basic deployment options.

16.1. Installing the Usage Server (Optional)

You can optionally install the Usage Server once the Management Server is configured properly. The Usage Server takes data from the events in the system and enables usage-based billing for accounts.

When multiple Management Servers are present, the Usage Server may be installed on any number of them. The Usage Servers will coordinate usage processing. A site that is concerned about availability should install Usage Servers on at least two Management Servers.

16.1.1. Requirements for Installing the Usage Server

•The Management Server must be running when the Usage Server is installed.

•The Usage Server must be installed on the same server as a Management Server.

16.1.2. Steps to Install the Usage Server

1.If you are on RHEL/CentOS 5.x, use the following command to set up an Extra Packages for Enterprise Linux (EPEL) repo:

#rpm -Uvh http://mirror.pnl.gov/epel/5/i386/epel-release-5-4.noarch.rpm

2.Run ./install.sh.

#./install.sh

You should see a few messages as the installer prepares, followed by a list of choices.

3.Choose "S" to install the Usage Server.

4.Once installed, start the Usage Server with the following command.

# service cloudstack-usage start

The Administration Guide discusses further configuration of the Usage Server.

16.2. SSL (Optional)

CloudPlatform provides HTTP access in its default installation. There are a number of technologies and sites which choose to implement SSL. As a result, we have left CloudPlatform to expose HTTP under the assumption that a site will implement its typical practice.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
