FTP Load Balancing in AWS

Our company currently uses several F5s in our on premise datacenter for load balancing FTP. We are now trying to implement load balanced FTP servers in AWS (which are backed buy S3 storage). For proof of concept we've been able to get passive FTP working with HAProxy in AWS, but not active/port FTP due to networking constraints in AWS. Do you have a pattern for load balancing several FTP servers behind an F5 AMI appliance that works with both active and passive? We are already comfortable with the F5s, so it'd be a great way to go if we know it'll work.

 

Thanks, Dan Cunningham

    The F5 AMI's will behave the same as your on-premise LB's so the configuration for vip, monitors, and YES/NO to SNAT should remain the same. I haven't configured FTP in Amazon yet per se, but my more complex on-premise configs migrated seamlessly to AWS. I use Globalscape EFT using their DMZ proxy architecture and it handles most of the complex routing for segregated FTP services, and the BIG-IP is really just LBing the proxies; the proxies do act as the FTP server and then setup a proprietary connection to the "storage" locations behind it.

     

    BIG-IP in AWS does offer a free trial (30 days I think) so you could actually set this up and test it for free. :-)
