As a core tutorial for OpenStack, we have come to the final summary. OpenStack currently has dozens of modules, this tutorial discusses the most important core modules: Keystone,nova,glance,cinder and neutron.

The entire life cycle of instance from creation to deletion is managed by Nova. In the following sections, we take the different operational scenarios in the instance life cycle as an example to analyze in detail how the different Nova components work together and deepen your understanding of Nova through log analysis.Before we study Nova's operations, let's start by learning one important thing: the OpenStack logs.OpenStack's log records very detaile
