“Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud.”
On their own, these instances contain very little, but allied with your own or third party AMI (Amazon Machine Instances) you can build an army of EC2 instances which allows you to quickly scale up and down a cluster of servers.
Powerful.

Below are the commands required to setup FTP (well, FTPS in fact, and specifically not SFTP, which you can most easily use by adding your security certificate to your FTP program and accessing over SSH) on your AWS EC2 cloud instance.

A quick and simple command you might need from time-to-time if you’re running apache webservers in one or other Linux flavour. We often grab EC2 instances on Amazon, for example, for our clients and, for various reasons, we want the server to know what time it is here in the UK! So here’s the command …
If you’re recently installed WordPress onto a new server (we do this a lot on Amazon EC2 instances of varying sizes) and you notice that your image uploads aren’t auto-thumbnailing (when WordPress “crunches” your images into “thumbnail” “medium” and “large” sizes for use throughout your website) then chances are your server doesn’t have the GD …
