Chapter 1 Architecture1.1OpenStack Architecture Overviewopenstack Project is an open-source cloud computing platform that can support multiple types of cloud environments. openstack The project is aimed at simple implementation, strong extensibility, and rich functionality. openstack Provide iaas the solution. Each service is provided with a api t

Compute Service Nova is the core of OpenStack services and is responsible for maintaining and managing computing resources in the cloud environment.OpenStack is the cloud operating system for IaaS, and virtual machine lifecycle management is achieved through Nova.As you can see, Nova is at the center of the Openstak architecture and other components support Nova:Glance provides an image for the VMCinder and

We discussed the basic concepts of Neutron, and today we begin to analyze the architecture of Neutron.Neutron ArchitectureLike other OpenStack services, Neutron also employs a distributed architecture that provides network services from multiple components (sub-services).The Neutron is composed of the following components:Neutron ServerProvide the

About Keystone module, I will from the overall architecture and functions, user information management, certification services 3 modules with 3 articles for analysis.1.

Opentack divides its own architecture into several application scenarios: General Purpose Compute focused Storage focused Network focused Multi-site Hybrid Examples of General perpose common scenarios are as follows: A company mainly provides Web applications, including tomcat, nginx, and mariadb. In this scenario, we use openstack to perform Load Balancing by using physical Server Load ba

The next few blog posts, bring you a simpler macro-architecture and detailed implementation of the deployment of the tutorial, no figure no JB----> The above cluster environment is briefly described as follows (2 represents the number of services or software, i.e. there are multiple identical services): 1, Nginx reverse proxy server (NGINX2, Keepalived2, yum source 1): The user all requests through the Nginx reverse proxy to distribute, and reali

Android adopts a hierarchical architecture like its operating system. From the structural diagram, Android is divided into four layers: application layer, application framework layer, system Runtime Library layer, and Linux core layer. Android Architecture 1.
