written by well-known professors such as Tsinghua University. I have my own personal experience in this regard. I first downloaded the ajax video tutorial of Chuanzhi podcast, but I couldn't read it after reading a few sections. Later I bought another AJAX technology book, A thick 60 yuan copy. It was also very hot. After eight days of patience, I couldn't see it anymore. I felt that AJAX technology was very profound and could not really comprehend it, so I gave up, go hiking, swimming, going t

So planning for shared storage ahead of time is key.SectionHere, we've learned about the OpenStack Nova architecture, discussed key components such as Nova Api,scheduler,compute, and analyzed the Nova operations in detail, and finally summed up the purpose and usage scenarios for these operations using a single graph.Nova is the most important project in OpenStack, at the cen

Instance, and the compute node itself is working properly. If the compute node fails, OpenStack cannot communicate with the node's nova-compute, and all instance running on it will be affected. At this point, the Instance can only be rebuilt on other normal nodes through the evacuate operation.EvacuateRebuilds Instance on other compute nodes using the Instance image file on the shared storage.
