Currently, I am taking a look at IBM's new Platform-as-as-Service (PaasS) offering code-named "Bluemix". Right now it is in open beta and I signed up on its official website http://bluemix.net. Bluemix is based on the open source Cloud Foundry. But how do you get started and get a good introduction to what is offered?
I read the article "What is IBM Bluemix?" on IBM developerWorks. It gives some background information and details that Bluemix offers Development Frameworks (develop in, e.g., Java, Ruby, or Node.js), Application Services (DB2, MongoDB, MySQL, and others), and Clouds, i.e., you can deploy your applications (apps) to public, private, or other clouds.
Next, I watched the following video which gives a nice overview about the different elements of the Bluemix user interface, including the dashboard.
Equipped with that background information and knowing about the UI, the next stop is the Bluemix website offering articles and sample code. One of the examples is on how to build a simple business intelligence (BI) service using Ruby and based on DB2 with BLU Acceleration, code samples included.
If you haven't tried it yet, you can still sign up for the free beta here: http://bluemix.net. Enjoy!
