Hi Techies, I have 2 URLs to consider. Out of this one is the main URL and other is the back up. So when I am putting out these two URLs for configuration in the front end with a apache server, I need the server to always send the request to main URL. If the main URL is down then the request can be sent to back up URL. I googled a lot and I could find out that we can load balance two URLs with a webserver in the front, but not able to find out how to put it in Fault Tolerance mode. Can you please help me on this. Thanks in Advance --- Nuveos.
This will depend on which http server you are running. With NGINX, you can specify an upstream backend server as a backup (which will activate only if requests to the primary upstream doesn't respond). This of course means you'll need NGINX up front, and not Apache. Apache can still act as the backend, answering only valid requests, which will save you a lot of headaches, and will amplify the amount of requests you can receive simultaneously.
