I came across the OStatic Free hosting service that provide Solaris + Glassfish (Java Container) + MySQL.
They offer “Now you can get free Web hosting on Cloud Computing environment free of charge for up to 12 months. ”
The catch “accumulate 400 Points for participating on the site“.
A rather novel approach, you get 100 points for registering, but then only 5-15 points per task. The equates to approximately at least 30 tasks you need to perform, such as answering a question, or reviewing somebodies application. That seems like a lot of work?
In this case, Free has definitely a cost and time factor to consider.
