  Abstract:
  Each process in the cloud requires an amount of CPU power, RAM memory, network bandwidth, hard disk space, etc. Multiple processes can share the same physical machine, as long as that machine has enough resources (CPU, RAM, etc) to accommodate for all those processes. Which processes do we put on the same machine? How do we organize our machines more efficiently? How do we run a better a service, with less hardware?
