There is another issue if your application has to deal with user uploaded files, such as photos, PDFs, etc. You must consider the instances in an autoscaling cluster to be volatile because they can come and go automatically. Consequently, you must have a way of ensuring that either the filesystems of those instances are synchronized or store user contributed files on Amazon S3. Fortunately, we have pluggable storage in Django so it's easy to do the latter. If you ever have to deploy an application that doesn't have that, as we did, we ended up creating an NFS cluster in a VPC (Virtual Private Cloud) and the instances in the autoscaling group mounted the exported NFS filesystem. The autoscale instances had two network interfaces, one for the public Internet and another for the internal network in the VPC, so the NFS cluster was not exposed to the Internet. -- Regards, Clifford Ilkay 647-778-8696 Dinamis <http://dinamis.com> -- You received this message because you are subscribed to the Google Groups "Django users" group.
