I mentioned Amazon.com lowering pricing for EC2 in my links entry today, but having great pricing is only useful if you have something to deploy on EC2.  And a great way to deploy applications is in GlassFish.

Now, anyone can install everything from scratch on their EC2 instance, but Amazon Machine Images (AMIs) are a great way to get a head start with a pre-installed/configured operating system and other software.  As you might expect, for someone wanting to use GlassFish there are several AMIs available.

My quick perusal came across the following GlassFish and related AMIs:

• OpenSolaris 2008.11 With GlassFish 2.1 and MySQL 5.1 Provided by Sun Microsystems, Inc. - Everything you need to get started with OpenSolaris, MySQL, and GlassFish.
• GlassFish ESB v2.1 on OpenSolaris 2008.11 32-bit AMI - For those wanting to take the step up from GlassFish to incorporate routing, transformation, and orchestration in their applications.  See Hari's blog for more info.
• OpenSSO AMIs - Running in GlassFish, provides for single-signon and Web services security.
