Hi All, We have read from others that the dynamic and large number VM provisioning might be a pain, e.g. <http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=6719385> http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=6719385 The scenario is that the number of instances for any application is continuously changing, and the number is as large as hundreds of instances in hundreds of nodes. However, with our limited investigation, we still see that it takes 200 seconds to 700 seconds for OpenStack to launch 100 instances. So, we wonder if large scale provisioning and the time involved could translate into a true pain for Datacenter operators? If it is, perhaps OpenStack already addresses this but we are just not aware. Would a more effective way of VM provisioning, if integrated into OpenStack, be of any value?
