Configuring GSLB

3.In each zone that are participating in GSLB, add GSLB-enabled NetScaler device. For more information, see Section 16.9.2.2, “Enabling GSLB in NetScaler”.

On CloudPlatform side, perform the following as a domain administrator or user:

1.Add a GSLB rule on both the sites.

See Section 16.9.2.3, “Adding a GSLB Rule”.

2.Assign load balancer rules.

See Section 16.9.2.4, “Assigning Load Balancing Rules to GSLB”.

16.9.2.1. Prerequisites and Guidelines

•The GSLB functionality is supported both Basic and Advanced zones.

•GSLB is added as a new network service.

•GSLB service provider can be added to a physical network in a zone.

•When users have VMs deployed in multiple availability zones which are GSLB enabled, they can use the GSLB functionality to load balance traffic across the VMs in multiple zones.

•The users can use GSLB to load balance across the VMs across zones in a region only if the admin has enabled GSLB in that region.

•The users can load balance traffic across the availability zones in the same region or different regions.

•The admin can configure DNS name for the entire cloud.

•The users can specify an unique name across the cloud for a globally load balanced service. The provided name is used as the domain name under the DNS name associated with the cloud.

The user-provided name along with the admin-provided DNS name is used to produce a globally resolvable FQDN for the globally load balanced service of the user. For example, if the admin has configured xyztelco.com as the DNS name for the cloud, and user specifies 'foo' for the GSLB virtual service, then the FQDN name of the GSLB virtual service is foo.xyztelco.com.

•While setting up GSLB, users can select a load balancing method, such as round robin, for using across the zones that are part of GSLB.

•The user shall be able to set weight to zone-level virtual server. Weight shall be considered by the load balancing method for distributing the traffic.

•The GSLB functionality shall support session persistence, where series of client requests for particular domain name is sent to a virtual server on the same zone.

Statistics is collected from each GSLB virtual server.

16.9.2.2. Enabling GSLB in NetScaler

In each zone, add GSLB-enabled NetScaler device for load balancing.

1.Log in as administrator to the CloudPlatform UI.

2.In the left navigation bar, click Infrastructure.

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.
