End-of-Life (EoL)
This section shows you how to set up the NetScaler VPX load balancer for this use case. These instructions are included solely for the purpose of taking you through the implementation in this use case. For set up and conceptual information on the NetScaler VPX, refer to the Citrix documentation.
Configure the Citrix NetScaler VPX
Launch the NetScaler VPX and assign an Elastic IP Address. Launch the NetScaler VPX. Allocate and associate Elastic IP Addresses for the firewall and the NetScaler VPX.
Configure the Virtual IP and the Subnet IP on the NetScaler VPX. On the NetScaler management console, select Configuration > System > Network > IPs. Add the Virtual IP and the Subnet IP addresses.
Add static routes to direct traffic to the web servers. Make sure to add routes for the web servers in both Availability Zones. Add the routes in Configuration > System > Network > Routes. In this example, we add routes to direct traffic from web1 and web2 through eth 1/1 on AZ1-FW1 and traffic from web 3 and web4 to eth1/1 on AZ1-FW2.
Create a service for each web server. Add the web services in Configuration > Traffic Management > Load Balancing > Services.
Configure the virtual server. The Virtual server IP address is the only IP address that is exposed to users who connect to the web server from the internet. Add a Virtual Server IP address in Configuration > Traffic Management > Load Balancing > Virtual Servers.
Bind the web services you created in Step 4 to this virtual server. Edit the settings for the virtual server to enable IP address persistence. IP address persistence is required for the application to authenticate properly. Based on your preference, select Cookie-based or Source-IP-based persistence.
Test your configuration. Verify that you can log in to the web server. The WordPress application in this use case would be accessible at http://ignite-aws-demo.com/wordpress.
