Setting Up Networking for Users

Chapter 10.

10.1. Overview of Setting Up Networking for Users

People using cloud infrastructure have a variety of needs and preferences when it comes to the networking services provided by the cloud. As a CloudPlatform administrator, you can do the following things to set up networking for your users:

•Set up physical networks in zones

•Set up several different providers for the same service on a single physical network (for example, both Cisco and Juniper firewalls)

•Bundle different types of network services into network offerings, so users can choose the desired network services for any given virtual machine

•Add new network offerings as time goes on so end users can upgrade to a better class of service on their network

•Provide more ways for a network to be accessed by a user, such as through a project of which the user is a member

10.2. About Virtual Networks

A virtual network is a logical construct that enables multi-tenancy on a single physical network. In CloudPlatform a virtual network can be shared or isolated.

10.2.1. Isolated Networks

An isolated network can be accessed only by virtual machines of a single account. Isolated networks have the following properties.

•Resources such as VLAN are allocated and garbage collected dynamically

•There is one network offering for the entire network

•The network offering can be upgraded or downgraded but it is for the entire network For more information, see Section 16.5.1, “Configuring Isolated Guest Network”.

10.2.2. Shared Networks

A shared network can be accessed by virtual machines that belong to many different accounts. Network Isolation on shared networks is accomplished by using techniques such as security groups, which is supported only in Basic zones.

•Shared Networks are created by the administrator

•Shared Networks can be designated to a certain domain

•Shared Network resources such as VLAN and physical network that it maps to are designated by the administrator

•Shared Networks can be isolated by security groups

•Public Network is a shared network that is not shown to the end users

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.
