White Paper Deployment Practices and Guidelines for NetScaler 10.1 on Amazon Web Services White Paper NetScaler 10.1 on AWS Citrix NetScaler on Amazon Web Services (AWS) enables enterprises to rapidly and cost-effectively leverage world-class NetScaler application delivery capabilities within their Amazon Web Services deployments. NetScaler on AWS combines the elasticity and flexibility of the AWS Cloud with the same optimization, security and control NetScaler provides for the most demanding websites and applications in the world. Because the corresponding Amazon Machine Image (AMI) is a packaging of the same binary used on NetScaler MPX™/NetScaler SDX™ hardware and NetScale VPX™ virtual appliances, enterprises obtain all of the same L4-7 functionality familiar from their on-premise deployments, including load balancing, content switching, global server load balancing, application firewall and SSL VPN. This enables numerous compelling use cases, from hybrid cloud (i.e., spillover) and production delivery scenarios, to implementations for business continuity and application development and testing. Due to some of the design characteristics of the AWS Cloud, however, there are a handful of differences that network architects need to be aware of with regard to how NetScaler® on AWS works and, therefore, how it needs to be configured. For example, because AWS does not expose Layer 2 networking capabilities to customers, administrators will need to enable high availability pairs differently than they do with their on-premise deployments. Broken into three distinct sections, this paper: ® • Further examines the potential use cases for NetScaler on AWS, including the role of Citrix CloudBridge™. • Provides a primer on the nomenclature, high-level architecture and networking details applic
