Service Offerings

Chapter 9.

In this chapter we discuss compute, disk, and system service offerings. Network offerings are discussed in the section on setting up networking for users.

9.1. Compute and Disk Service Offerings

A service offering is a set of virtual hardware features such as CPU core count and speed, memory, and disk size. The CloudPlatform administrator can set up various offerings, and then end users choose from the available offerings when they create a new VM. A service offering includes the following elements:

•CPU, memory, and network resource guarantees

•How resources are metered

•How the resource usage is charged

•How often the charges are generated

For example, one service offering might allow users to create a virtual machine instance that is equivalent to a 1 GHz Intel® Core™ 2 CPU, with 1 GB memory at $0.20/hour, with network traffic metered at $0.10/GB. Based on the user’s selected offering, CloudPlatform emits usage records that can be integrated with billing systems. CloudPlatform separates service offerings into compute offerings and disk offerings. The computing service offering specifies:

•Guest CPU

•Guest RAM

•Guest Networking type (virtual or direct)

•Tags on the root disk

The disk offering specifies:

•Disk size (optional). An offering without a disk size will allow users to pick their own

•Tags on the data disk

9.1.1. Creating a New Compute Offering

To create a new compute 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 Compute Offering.

4.Click Add Compute Offering.

5.In the dialog, make the following choices:

•Name: Any desired name for the service offering.

•Description: A short description of the offering that can be displayed to 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.
