1.1OpenStack Architecture Overview

openstack 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 to facilitate integration. Each openstack services:

service                                                               

dashboard                     Horizon                                    web admin interface, with openstack Each service interacts

Compute Nova Manage virtual machine instance operations, including build, resource scheduling , and more

Networking Neutronto beOpenStackOther services availableNetwork-connectivity-as-a-service, such asOpenStackcalculations. To provide users withAPIto define the network, etc.

Block Storage Cinderprovides stable block storage for running instances. The pluggable drive architecture facilitates the creation of block storage devices and                                                                               Management

1.3 Sample Schemas

OpenStack highly configurable to meet the different requirements for computing, networking, storage. This is a sample architecture for the Neutron network, which requires at least three nodes:

• Control Node(Controllernode)Running certification Services(Identity service), mirroring Services(Imageserivce), Calculation(Compute)and Network(Networking)The Management section, the network plug-in(Networking plug-in)as wellDashboard, it also provides basic services, includingNTPServices, database services, information queuing Services

• Network Node (Networknode) run the network plug-in with the client to provide the tenant network with interaction, routing, NAT , DHCP service. The node handles network connections inside and outside the virtual machine instance

• COMPUTE Nodes (Computenode) that runs the virtual machine instance. hypervisor section, by default, the compute service uses the KVM as a hypervisor
