A good article at Java World outlines the deisgn principles of building cloud ready multicore applications.
“For your applications to meet the demands of computing in a cloud-based, multicore world, you’ll need to design your code with the following attributes in mind:
- Atomicity
- Statelessness
- Idempotence
- Parallelism
In this article, the first of two parts, I’ll discuss each [...]
