[openstack-community] Openstack achieve the elasticity for computation
Hi, IaaS is all about elastic computing. I can stretch resources as per my need - increasing/decreasing the number of cores, RAM allocated etc.. My question is - how does openStack achieve this elasticity for both computation and RAM. If I create an image with 2 cores and 4 GB RAM (and one day I need to increase this to, lets say - 6 Cores and 12 GB RAM), but all the physical hosts that I currently have (for Compute and RAM) at my disposal have a max of 4 Cores and 4 GB RAM each.. Using openStack - a) is this possible (as long as the total cores and total RAM required is less than the group-total) ? If yes, how is this achieved. b) or the elasticity will be limited to 4 Cores/4GB (The max capacity of a physical host) ? If no, then is it possible to achieve it ?
