Many people have told me that they have used the ElasticFox extension for Firefox to get started with Amazon EC2. ElasticFox makes it easy to see the list of available AMIs (Amazon Machine Images), to launch any number of instances of those AMIs, and to monitor and manage the running instances:

We just released version 1.4 of this powerful tool. In addition to wiping out some bugs related to security groups and key management, ElasticFox now supports all of the features of the newest version of the EC2 API - Availability Zones, Elastic IPs, and user-selectable kernels. There are new tabs for kernels and ramdisks, Elastic IPs, and Availability Zones:

An IP address can be allocated and then attached to a running EC2 instance with a couple of clicks:

New instances can be launched in any availability zone, with full control of the kernel (AKI) and ramdisk (ARI):

Finally, you can now filter the AMI list using the box at the top right:

I added this feature myself because I had been spending too much time scrolling through the ever-expanding list of available AMIs during my conference and user group demos.

And that brings me to my last point: ElasticFox is an open source project hosted on SourceForge. It was easy to download the code to my desktop machine (I used TortoiseSVN), install FireBug, figure out how the code worked, and to make and test my changes.

We've got ideas for even more features, but there's no reason to wait for us. If you have some ideas of your own, grab the code, do your thing, and send us your code for review and checkin.

PS - We are planning to release a version of this extension which is compatible with version 3 of Firefox. This version is well under way, but we didn't want to hold up release of these great new features in anticipation of the production release of Firefox 3.

Update: If you are brave and somewhat fault-tolerant, you can download and try out the Firefox 3 version here. This version is reportedly faster, and also more responsive -- the UI doesn't freeze when the extension makes background calls to EC2. Please file bugs as you find them (you will need a SourceForge account in order to do so).

I saw a few people looking for solutions to off-load wpmu files to Amazon-S3 service. This is something we wanted to try on our installation (just a few thousand blogs) so I wrote a plugin that will serve themes css and image files from S3.

The plugin uses the ‘stylesheet_directory_uri‘ filter to set the stylesheet uri (css file). In turn, the stylesheet uses the ‘url‘ method to call the image files of the theme so they get the same base url as the stylesheet. Most themes uses the ‘stylesheet_directory‘ call correctly so you will not run into trouble but if a theme uses it to call a php file you should change the call to use ‘template_directory‘.

Download: themes-s3.zip

Usage:

1. Signup for an Amazon-S3 account.
2. Create a bucket for your files. Since you have to select a globally unique name for your buckets I call it s3.domain.com were domain.com is my wpmu installation.
3. To point s3 to your bucket setup a CNAME record: s3 -> s3.domain.com.s3.amazonaws.com. (don’t forget that extra dot at the end).
4. Load your themes css and image files to your bucket keeping the exact directory structure for each theme (/wp-contents/themes/… ). You can use the excellent S3 FireFox Organizer to mange your files.
5. Edit the plugin to include your bucket name.
6. Place the plugin in the mu-plugins directory.
7. Test, test and test all your themes!

Whats next? The next step I’m planning is to off-load the Java Scripts in the wp-includes folder. Also planned is an option to serve the users files from S3. If you are interested in helping in any way please leave a comment and we can take it from there.
