node.The scheduling service is like a project manager in a development team, and when a new development task is received, the project manager assigns the task to the most appropriate developer based on the difficulty of the task, the current workload and skill level of each team member.Worker Work ServicesThe dispatch service just assigns tasks, and the worker work service is the real task. In Cinder, this Worker is cinder-volume. This functional division between Scheduler and workers makes

What is OpenStack? OpenStack provides open source software to build public and private clouds. OpenStack is a community, project, and open source software that helps enterprises run virtual computing or storage cloud. The OpenStackd open-source project is maintained by the community, including OpenStack computing (code

Nova is a compute service that can start a virtual machine instance. These services can be configured on a separate node or on the same node. Most services run on the controller node and run the virtual machine service on a dedicated compute node. This time, we deploy the compute to the control node.4.1 Install Compute Controller services (Installation Compute service)4.1.1 installation of compute required Packages# yum Install Openstack-nova-api
