Hi all, This is my first post so please excuse if i've missed 
some etiquette.

Im currently developing my first 'Production' server that will be Node.js 
running on a PaaS (likely a cloud foundry based solution) and while playing 
about with the command line interface i found out something interesting. 
Each "instance" of my application reports having 8 cores avaliable.

+----------+-------------+----------------+--------------+----------------+
| Instance | CPU (Cores) | Memory (limit) | Disk (limit) | Uptime         |
+----------+-------------+----------------+--------------+----------------+
| 0        | 0% (8)      | 20.1M (64M)    | 30.7M (1G)   | 0d:17h:37m:6s  |
| 1        | 0% (8)      | 20.6M (64M)    | 0B (1G)      | 0d:17h:51m:20s |
| 2        | 0% (8)      | 19.7M (64M)    | 30.7M (1G)   | 0d:17h:51m:20s |
| 3        | 0% (8)      | 19.6M (64M)    | 30.7M (1G)   | 0d:17h:26m:0s  |
| 4        | 0% (8)      | 20.2M (64M)    | 30.7M (1G)   | 0d:17h:26m:0s  |
+----------+-------------+----------------+--------------+----------------+

Now my understanding of cloud foundry is only consumer at best, i know that 
is essentially a virtual machine running some sort of OS with node 
installed. 

What i am wondering now is when i add more "instances" of my application is 
this the same as just having another thread of me node program and these 
are the same 8 cores that each thread can see? or am i actually getting a 
whole other VM with its own 8 cores (seems unlikely). 

Also if this is the case (that with five instances i actually have 40 
cores) should i be doing my own thing in my node app to start 7 more clones 
of my node app to get the best usage out of the resources?

Love to hear anyone's thoughts on this 

Chris
