Hello,

We are installing nginx for the first time. Could someone please comment on the deployment architecture we selected.

Is the architecture illustrated below the best one to meet the following objectives:

- A physical host with a single public IP address must be virtualized into many virtual servers. These virtual servers run Apache and must be reachable from the single public IP.
- Static content from the virtual servers must be cached
- One of the virtual servers runs Puppet server. We wish to optimize Puppet server performance by using caching and load balancing of the backend Mongrel servers.

The architecture to meet these objectives is illustrated below. In this design:

- Nginx for reverse proxy and caching proxy runs on a virtual server and answers all requests from the public IP address. As a reverse proxy, nginx routes requests to the appropriate virtual server. It also serves static content from these virtual servers.
- On the virtual server running puppet, we use a second instance of nginx, which is configured with the Fair Load Balancer to serve requests to the Mongrel servers.

Is this the optimal configuration of nginx for these objectives? Could the above objectives be met with only a single instance of nginx?

Any comments or suggestions would be greatly appreciated.

Thank you,
