Recently, when looking for a job, I was asked some principles of Swift's bottom, so I decided to take notes in order to be able to impress.
The following is reproduced by (http://www.openstack.cn/?p=776)

Use cases that use scale-out effects that are better than vertical scaling are the ideal object for general-purpose cloud architectures.A general-purpose cloud environment is potentially useful and functional, rather than customized for a given user. The general purpose architecture is designed to meet 80% of potentially available cases. The infrastructure itself is a designated case, intended as a basic model of the design process. Th

Through this article, you will be able to understand how to configure the hybrid hypervisor in openstack and the basic analysis of its implementation principles. This article analyzes the principles of the hybrid hypervisor scenario in openstack based on the actual development experience of the author in Nova, and introduces how to configure the hybrid hypervisor scenario in actual application scenarios.

The current problemThere are currently two main ways to upgrade and downgrade OpenStack, based on the image and package-based.The update is atomic based on the image method.Package-based updates are usually not atomic, there are many reasons for failure during the upgrade process, and there may be some possible failure of the package update.Usage Scenarios

Introduction to OpenStack Architecture analysis written in frontLearning Goals:
Understand the logical relationships of OpenStack components;
Understand the communication and deployment relationships of the various components of OpenStack;
Understand the work flow of OpenStack;

192.168.230.5 as in the Redis master container, the data synchronization between the Redis master and Redis slave works normally, the following information is queried from the Redis slave container running on 192.168.230.5:It can be seen that the data synchronization between the Redis master and Redis slave is normal, and the ovs gre tunnel technology enables normal communication between containers across machines.
