Chapter 16. Managing Networks and Traffic

•When you create a guest network, the network offering that you select defines the network persistence. This in turn depends on whether persistent network is enabled in the selected network offering.

•An existing network can be made persistent by changing its network offering to an offering that has the Persistent option enabled. While setting this property, even if the network has no running VMs, the network is provisioned.

•An existing network can be made non-persistent by changing its network offering to an offering that has the Persistent option disabled. If the network has no running VMs, during the next network garbage collection run the network is shut down.

•When the last VM on a network is destroyed, the network garbage collector checks if the network offering associated with the network is persistent, and shuts down the network only if it is non- persistent.

16.28.2. Creating a Persistent Guest Network

To create a persistent network, perform the following:

1.Create a network offering with the Persistent option enabled. See Section 10.5.1, “Creating a New Network Offering”.

2.Select Network from the left navigation pane.

3.Select the guest network that you want to offer this network service to.

4.Click the Edit button.

5.From the Network Offering drop-down, select the persistent network offering you have just created.

6.Click OK.

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.
