comment Nginx rewrite URL only if file exists
This checks to see if the file exists, and if that test fails, it redirects to new_images. What happens after that is not specified here.

comment Virtual Machine memory usage not appearing in TaskManager
Unfortunately, there is no single number that indicates "how much memory" a process is using, since you get into complications like shared memory, file-mapped memory, paged-out memory and a few others. Here's a good explanation of a few concepts: stackoverflow.com/questions/1984186/…

comment Benefits of Gigabit uplink for high traffic webserver?
Not necessarily. Your cost/benefit of using EC2 for a simple web installation is not particularly appealing. Unless you need the benefit of dynamic server allocation, you can get 2x to 3x the performance per dollar running on dedicated hardware (at the right datacenter).

comment PTR record (rDNS) for multiple domains on a shared IP address
@Warner: the solution would be to make the MX record match the hostname, then. The MX record (target) doesn't need to relate at all to the email destination address.

comment Frequently accessed files and I/O usage
As long as you have enough memory free, Linux will cache your most recently used files in RAM, creating similar performance as with a ram disk.

comment Is S3 cheaper than a EC2 DIY solution (for small files)
It's worth pointing out that the 160GB of local storage is temporary. If you shut down the instance, the data is gone forever.
