[Openstack] 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 ? ___ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack

Thanks Cristian, Will elasticity be limited to 4 Cores/4GB (The max capacity of a physical host) ?

Re: [Openstack] Openstack achieve the elasticity for computation
Thanks everyone for your valuable point. Kindly allow me to put my Question in different way. Shall any VM use distributed(for eg. RAM from the different host) resources at the same time? or Shall any VM use two cores(that lies on different hosts) at the same time?, in the distributed fashion.

The same is valid for using swap as memory to reach the desired 12gb. Of course, if you don't plan on using that machine for any real work, you can do it.
