Modifying or Deleting a Service Offering

•Disk Size. Appears only if Custom Disk Size is not selected. Define the volume size in GB.

•QoS Type. Three options: Empty (no Quality of Service), hypervisor (rate limiting enforced on the hypervisor side), and storage (guaranteed minimum and maximum IOPS enforced on the storage side). If using QoS, make sure that the hypervisor or storage system supports this feature.

•(Optional) Storage Tags. The tags that should be associated with the primary storage for this disk. Tags are a comma separated list of attributes of the storage. For example "ssd,blue". Tags are also added on Primary Storage. CloudPlatform matches tags on a disk offering to tags on the storage. If a tag is present on a disk offering that tag (or tags) must also be present on Primary Storage for the volume to be provisioned. If no such primary storage exists, allocation from the disk offering will fail..

•Public. Indicate whether the service offering should be available all domains or only some domains. Choose Yes to make it available to all domains. Choose No to limit the scope to a subdomain; CloudPlatform will then prompt for the subdomain's name.

9.1.3. Modifying or Deleting a Service Offering

Service offerings cannot be changed once created. This applies to both compute offerings and disk offerings.

A service offering can be deleted. If it is no longer in use, it is deleted immediately and permanently. If the service offering is still in use, it will remain in the database until all the virtual machines referencing it have been deleted. After deletion by the administrator, a service offering will not be available to end users that are creating new instances.

9.2. System Service Offerings

System service offerings provide a choice of CPU speed, number of CPUs, tags, and RAM size, just as other service offerings do. But rather than being used for virtual machine instances and exposed to users, system service offerings are used to change the default properties of virtual routers, console proxies, and other system VMs. System service offerings are visible only to the CloudPlatform root administrator. CloudPlatform provides default system service offerings. The CloudPlatform root administrator can create additional custom system service offerings.

When CloudPlatform creates a virtual router for a guest network, it uses default settings which are defined in the system service offering associated with the network offering. You can upgrade the capabilities of the virtual router by applying a new network offering that contains a different system service offering. All virtual routers in that network will begin using the settings from the new service offering.

9.2.1. Creating a New System Service Offering

To create a system service offering:

1.Log in with admin privileges to the CloudPlatform UI.

2.In the left navigation bar, click Service Offerings.

3.In Select Offering, choose System Offering.

4.Click Add System Service Offering.

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.
