Apache+Tomcat VS Stand Alone Tomcat or GlassFish

Hi, I am setting up a Debian server to serve Java web applications. I have done quite a bit of research for several weeks now. Tomcat's web site says it is better to use stand alone Tomcat for speed if you are not clustering. However, I have seen many people suggest that using Apache + Tomcat gives you better security and protection against attacks. Please assume that the process will be running on port 80 as an unprivileged user. I would assume that if you are running a firewall in front the server, Tomcat should be fine. If, however, you just want to run an exposed webserver using Linux firewall, what is the best option? Or maybe someone can recommend another open source web server. I am trying to keep the solution as light as possible as these webapps will be running in containers. All opinions welcome and valued. Thanks, Tony Z

Reverse Proxy FTP traffic

- by TonyZ

I was wondering if anyone knew of a reverse proxy server to reverse proxy ftp traffic. I would like to run many servers on ip address, but then pass the traffic to an internal server with its own ip address. Thank you for any suggestions.

Measure Total Bandwidth for Billing

- by TonyZ

I am setting up a new network which customers will host their applications on. It needs to be able to scale out to a few hundred servers and each server will have several VMs on it. Right now in my test environment, after the telco router, we are using a Linux router/firewall which is then connected to a Layer 2 switch. Could be a layer 3 in the future. I need to track total bandwidth per VM for each machine, and I need to do it in a way that it is not part of the VM. Each VM will have a private class ip address which is Natted by the gateway, or we may eventually run more than firewall/reverse proxy off a layer 3 switch. So my thinking is that I can do it off of a promiscuous port on the switches, or at the gateway firewall. I would like to have an out of the box solution, preferably open source. Does anyone have suggestions on the easiest way to set this up, and the easiest tool to use. I have looked at the web sites for Nagios, Zenoss, Zabbix, ntops on the firewall, etc. It is hard to ascertain just from the web sites if they do exactly this or not. Obviously, performance is also somewhat key here. Anything running on the gateway should not drag it down doing traffic accounting. Thanks for any thoughts. Tony Zakula
