IBM WebSphere Portal 7 Farming and Amazon Cloud Hosting

Read :: Realizing an IBM WebSphere Portal farm topology on the Amazon Cloud
This sounds really good! While the concept is not new, it is new for the WebSphere Portal. However, there are some logical questions deriving from the article:

1. What is the Amazon Cloud/IBM licensing model for such setup?
Initially, Amazon and IBM partnership required a full license for each instance of Portal. Now there is an option to pay per usage and the prices are ranging from $7.26 to $27.93 per hour, depending on the type of instance chosen. :: Here are the available Amazon Cloud's IBM instances type and their pricing information

2. Ok, my company might use Amazon Cloud for our production Websphere needs, but what about the development part?
Amazon and IBM has a :: Development AMIs for ISVs program, where no license fees will be collected for development activities on available IBM software instance types.

3. Is WebSphere Portal moving away from the clustering concept?
Likely not, however maintaining and trying to add new nodes to a large cluster can be challenging, not to mention the associated licensing costs of maintaining a large number or portal nodes. This is a cost effective and going green solution for the portal world:)

4. What are the cons of such setup?
I will let you know after I set it up myself.

Creating a Custom WebSphere Portal 8 Theme with the Eclipse IDE

This is a very good IBM article on how to get started with your own custom theme for WebSphere Portal 8:  Deploying and developing IBM WebSphere Portal 8 themes: A step-by-step guide A couple of notes: While the article is mentioning RAD as a preffered tool, I was successfully able to use Eclipse IDE (with the WAS 8 server connector plugin provided by IBM).  I was working on Linux and I used the command line to mount the WebDAV shares ( WebDav Client on Linux ). You can also use Nautilus to connect to the WebDAV shares.
