Chapter 7. Steps to Provisioning Your Cloud Infrastructure

3.Click the Compute tab. In the Pods node, click View All. Select the same pod you used in step 1.

4.Click View Clusters, then click Add Cluster. The Add Cluster dialog is displayed.

5.In Hypervisor, choose OVM.

6.In Cluster, enter a name for the cluster.

7.Click Add.

7.5.3. Add Cluster: vSphere

Host management for vSphere is done through a combination of vCenter and the CloudPlatform UI. CloudPlatform requires that all hosts be in a CloudPlatform cluster, but the cluster may consist of a single host. As an administrator you must decide if you would like to use clusters of one host or of multiple hosts. Clusters of multiple hosts allow for features like live migration. Clusters also require shared storage.

For vSphere servers, we recommend creating the cluster of hosts in vCenter and then adding the entire cluster to CloudPlatform.

7.5.3.1. VMware Cluster Size Limit

The maximum number of hosts in a vSphere cluster is determined by the VMware hypervisor software. For VMware versions 4.2, 4.1, 5.0, and 5.1, the limit is 32 hosts. CloudPlatform adheres to this maximum.

Note

Best Practice: It is advisable for VMware clusters in CloudPlatform to be smaller than the VMware hypervisor's maximum size. A cluster size of up to 8 hosts has been found optimal for most real- world situations.

7.5.3.2. Adding a vSphere Cluster

To add a vSphere cluster to CloudPlatform:

1.Create the cluster of hosts in vCenter. Follow the vCenter instructions to do this. You will create a cluster that looks something like this in vCenter.

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.
