There is no additional cost over that of running your own AMI. We would appreciate your feedback on the utility you receive from these AMIs. We have intentionally kept it simple, but if there is something you would like or need to be able to use these, please let us know. |

To create these, we downloaded the latest stable release of memcached from memcached.org, built and tested memcached, and then integrated its startup into the image. When the AMI boots, it will automatically use nearly all of its memory for memcached. The "with-tools" instances have some browser based tools which allow you observe what the memcached instance is doing.
In most cases, there is no reason to log into the image. Just launch it and point your client to port 11211 (either TCP or UDP). If you want to see the extra tools, make sure your security group allows you to get to port 80, and point your browser at the public DNS name for the instance. Do be cautious about your security group settings on EC2 for the memcached port, as memcached does not have an authentication mechanism.
See Matt's post for more information on the "with tools" instances and Dustin Salling's memcached 1.4.0 post for more information on the original AMIs.
