By: Marius Sandbu

Overview of this book

With a large demand for responsive websites and availability of services, IT administrators are faced with an ever-rising need for services that are optimized for speed. NetScaler VPX is a software-based virtual appliance that provides users with the comprehensive NetScaler feature set. Implementing apps and cloud-based services is much easier with its increased service performance and integrated security features. This book will give you an insight into all the new features that NetScaler VPX™ has to offer. Starting off with the basics, you will learn how to set NetScaler up and configure it in a virtual environment including the new features available in version 11, such as unified gateway and portal theme customization. Next, the book will cover how to deploy NetScalar on Azure and Amazon, and you will also discover how to integrate it with an existing Citrix infrastructure. Next, you will venture into other topics such as load balancing Microsoft and Citrix solutions, configuring different forms of high availability Global Server Load Balancing (GSLB), and network optimization. You will also learn how to troubleshoot and analyze data using NetScaler's extensive array of features. Finally, you will discover how to protect web services using an application firewall and will get to grips with other features such as HTTP, DOS, and AAA.

Now that we have explored some of the different high availability features that NetScaler offers, it is also important to keep in mind that running NetScaler in a virtual environment requires planning with regards to where to place it. It is also important to have some sort of availability feature in place for the virtualization hosts, as having a high availability feature on NetScaler is not enough if something happens to the virtualization hosts.

We can consider having the following features:

  • Failover cluster: This allows us to have redundant virtualization hosts in case of hardware failure and so on

  • NIC teaming: This ensures continuous availability in case of NIC failure

  • Raid on local disks: This ensures that the system continues to run in case of hard drive failures

  • SAN redundancy: This ensures that the storage on which NetScaler resides is redundant

And, of course, these features should always be used in combination with a redundancy in NetScaler, as in regular high availability...
