The machines

Before installing any application, you need a machine. From what we just said, the machine must be close to the final one, but what does it mean in the machine's context?

The machine is often seen as its resources:

• The CPU: The computing power the application can use
• The memory: The space the application can use
• The disk space: The local storage the application can rely upon

Your first choice will be to pick the same CPU/memory/disk as the production machine. Yet make sure, before going this way, that the machine is not shared with other services (like another application), which can completely deserve the 1-1 choice in terms of resources (CPU, memory, disk, ...) because the resources would be consumed by the other application. ...
