Release of new whitepaper: Scalability and economics of XenApp on AWS


Here at Citrix we've recently completed a series of tests to verify the scalability of XenApp on single AWS instances.
As well as a series of tests to verify scalability and reliability of a larger XenApp farm, with 1000 concurrent users executing a realistic workload

This results of this work are published in this white paper.
We've also created a Excel spread sheet that is based on these findings and allows you to perform your own simulations.

CloudFormation Script available for creating your own XenApp farm on AWS

While performing the various scalability tests of XenApp farms on AWS it became clear we needed an automated means to install/setup/configure EC-2 instances, Windows domain infrastructures, networking ACLs, storage setups etc to allow us to install XenApp. AWS offers a great set of tools for this, called CloudFormation. We've just finished the work on the first of a CloudFormation script that based on a set of parameters you need to supply constructs in 3 hours a complete functioning XenApp farm ready for a pilot, POC or production.

Follow the below links to the CloudFormation script itself as well as the accompanying documentation.

Citrix Cloud Solutions for Amazon VPC

Amazon Virtual Private Cloud (Amazon VPC) lets you provision a private, isolated section of the Amazon Web Services (AWS) Cloud where you can launch AWS resources in a virtual network that you define. With Amazon VPC, you can define a virtual network topology that closely resembles a traditional network that you might operate in your own datacenter. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways.

You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your Access Gateways or NetScalers that has access to the Internet, and place your backend systems such as databases or XenApp servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.

Additionally, you can create a Hardware Virtual Private Network (VPN) connection between your corporate datacenter and your VPC and leverage the AWS cloud as an extension of your corporate datacenter.


Citrix Cloud Solutions for Amazon EC2


Amazon EC2's simple web service interface allows customers to obtain and configure capacity with minimal friction. It provides companies with complete control of the computing resources and lets customers run on Amazon's computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing companies to quickly scale capacity, both up and down, as computing requirements change. Amazon EC2 changes the economics of computing by allowing payment only for capacity used.
