Firewall and Switch High Availability Design for SaaS Application
Posted on 2008-11-17
Hi, I have a SaaS application for which I want to build a high available network infrastructure that consists of two firewalls, two switches, two load balancers, and two web servers. The application is a flash application served to clients over the internet who log on and access their data. I have budget for only 1 line to the internet. How do I wire these devices together to minimize single points of failure with only 1 internet line, and what cisco device model's would you recommend? The throughput is about 5-10mbps to the internet. The web server will be dual homed (1 connection to a front end vlan going to the internet, and the other connection to a backend vlan which should also be highly available and connecting the rest of the application). The servers will be Dell servers with DRACs connected. In total I will need approx 130 switch ports. I'm thinking two 6513's could handle both my front end and back end vlans, but I'm not sure. Your help would be greatly appreciated. Thanks.
