Simple DNS failover software!

$30-250 USD

Paid on delivery
I need simple failover software that continuously monitors my servers and notifies me when there is any trouble, and redirects traffic to standby servers. Monitoring is done by polling at configurable intervals and criteria (port 80, 21 etc). Whenever the server is not responding as expected the software can send a notification by mail. When the server is offline, the software must dynamically update the DNS records on my DNS servers! My two servers are in two different geographical locations, each running web-server software. This software is installed on both servers, each server will be configured to monitor both web-servers and update DNS-server. If one of the servers fails, the software on the other will update DNS to point the domain name to itself only. It must be a Windows application that runs under Windows 2008/2012.

I am an expert .NET developer with more than 9 years of experience in developing different types of applications from windows form to WCF services. I am ready to develop the app for you. I can develop it as a windows service so you can run it in background of your web servers. What is your DNS server? Is it a Microsoft DNS service (ad server) or is it bind? Please see my profile and also consider my bid.

I am CCIE (networking expert) and a python developer. Being a networking expert I know different scenarios (black outs, brown outs) that affect servers and how to draw a balance between convergence (quick fail-over) and stability. Let me know if you would like to get it coded in python, which will make it portable and you can easily use it for other servers later on. And being in python the maintenance will be easier and cheaper. I will make the code highly configurable so that you tweak it for different types of servers. The only information that I need from you to start coding is the update of DNS - What type of DNS server are you running ? How does it receive an update, does it have an API or it use web get request. I will also be thoroughly testing the code in my own network servers. Regards, Summit

Hello there, I am more than happy to help you with this project but it seems like you're trying to solve your problem in a not very so efficient way. I think the alert mechanism is pretty reasonable however, changing DNS on the fly isn't a very good practice as you can use a reverse proxy which is better suited for the task. Can you please provide me with a little more details about your servers (including the DNS server) so I can see what we can do, however, if you're happy with your solution, I am more than happy and capable to get it done as you like. Cheers, omeid
