Finally it happened. EC2 is available for everybody. And more than that they now provide servers with 7.5GB and 15GB of RAM per instance. Sweet.
For a lot of companies EC2 was not viable due to high memory requirements of some of the applications. Splitting up such tasks to use less memory on multiple servers was possible, but not really cost and time efficient. The release of new types of instances removes that road block and would probably invoke significant curiosity from memory crunching application developers.
$0.10 - Small Instance (Default)
