Re: HAProxy in Amazon EC2 in peer mode
Hi, This kind of scenario is really dependent from your configuration. Basically, you want to configure HAProxy to load-balance SSL services hosted by your application servers. Persistence based on SSLID into HAProxy, sharing the stick-table between both haproxy. This may work, but be carefull with the peers section, since your LB will change their IP addresses each time they'll reboot... cheers On Tue, Feb 7, 2012 at 1:56 AM, Mir Islam mis...@mirislam.com wrote: Hi, I am thinking of the following scenario to implement in AWS.

Thanks Mir
Re: HAProxy in Amazon EC2 in peer mode
You can also write a script that gather instances' data (using the EC2 APIs) in order to get the IPs. That way you can update the HAProxy configuration files when a change in your setup occurs.

And then refer to each other via those EIP. Here is a quick and dirty diagram of howI am thinking of implementing. Ofcourse the main cost is the static IP addresses that I have to get from Amazon.
Re: HAProxy in Amazon EC2 in peer mode
Just in case anyone was following in my effort to get HAProxy running in EC2. The peers mode will not work in EC2 because the IP address identified in the peer section must be an ip which is bound to the interface. I could not find a way to bypass it. Since the static IP assigned in EC2 are not really bound to the interfaces on the vm itself, it appears for the time being it is not possible to run in peer mode with static IP. It is possible to use the internal 10.x.x.x IP assigned by Amazon but that may change after a reboot. Oh, well I guess it is what it is.
