Your application will execute on a virtual computer that we call an instance. You have the choice of several instance types, allowing you to select a configuration of memory, CPU, and instance storage that is optimal for your application:

Small Instance:

1.7 GB of memory, 1 EC2 Compute Unit (1 virtual cores with 1 EC2 Compute Unit), 160 GB of instance storage, 32-bit platform $0.10 per instance-hour consumed or partial hour consumed

Large Instance:

7.5 GB of memory, 4 EC2 Compute Units (2 virtual cores with 2 EC2 Compute Units each), 850 GB of instance storage, 64-bit platform $0.40 per instance-hour consumed or partial hour consumed

Extra Large Instance:

15 GB of memory, 8 EC2 Compute Units (4 virtual cores with 2 EC2 Compute Units each), 1690 GB of instance storage, 64-bit platform $0.80 per instance-hour consumed or partial hour consumed

See Amazon EC2 Instance Types for details on available configurations. You have full and exclusive access to an instance once you have commissioned it.

install rails 2.0

sudo gem install rails -f  -d -y --source http://gems.rubyonrails.org

Seems that the previous step is not enough, in order to install (really install) the edge, we still need to freeze:

rake rails:freeze:edge TAG=rel_2-0-0_PR

And I've also read in few places that the last step needs to be ran twice (don't ask)

And finally in order to get some rake problems sorted out, I had to do a rake gem update:

sudo gem update rake

Java Date formatting

Many people complaining that date formatting is a paing in java. It might be easier then you think. Here is the example:

DateFormat fDateFormat = DateFormat.getDateInstance(DateFormat.SHORT);
System.out.println(fDateFormat.format(new Date()));

For more details on DateFormat see the API: http://java.sun.com/j2se/1.4.2/docs/api/java/text/DateFormat.html

Axis

Potentially this is one more peace of technology that makes EJB layer obsolete. I'm going to repeat myself by saying that most of EJB layer features can be sufficiently replaced with other technologies like AOP for instance. The only thing that is hard to replace is MDB. Axis is the answer -- it supports asynchronous services and is great for communicating loosely coupled systems (I would say better then JMS).
