We currently have a dedicated web server and database server with Rackspace.
We have a new web app that we would like to bring up on the Rackspace Cloud service. We are looking at the RackConnect option, which will allow the cloud web server to connect to our existing db server.
We initially were thinking about putting this new web app on our existing web server as well, then use an F5 load balancer for high availability, with the cloud web server handling the majority of the traffic. Once I found out how much that F5 load balancer is going to cost, which would blow my budget out of the water. So I started looking into other configs.
The other config I was thinking about is this: Create 2 new cloud web servers and spin up a cloud load balancer instead of getting the F5. Then the 2 cloud web servers can connect to the backend db server via the RackConnect. Can anyone tell me if this configuration will work? It would be considerably cheaper than throwing the F5 into the mix.
I appreciate any feedback on this proposed config.
