6 OpenStack Conceptual Architecture 資訊技術服務中心

7 OpenStack Logical Architecture Version : Grizzly

8 OpenStack Components 資訊技術服務中心 Computing OpenStack Compute (Nova) OpenStack Image service (Glance) Networking OpenStack Networking (Quantum) Storing OpenStack Object Storage (Swift) OpenStack Block Storage (Cinder) Identity ： Keystone Dashboard ： Horizon

9 資訊技術服務中心 OpenStack Components (Cont.) Nova Compute Compute resource management and Scheduler VM life cycle management and VNC proxy Glance Discovering, registering, and retrieving VM images Quantum Manage VM’s Network, assign floating IP, Iptables, openvswitch

10 資訊技術服務中心 OpenStack Components (Cont.) Swift Object Storage (ex. Amazon S3) Cinder Provides persistent block storage to VM Keystone User Identity Components need register to keystone Horizon Web dashboard 。 (ex. user login, VM create and terminate, volume create, security group and etc.)

11 OpenStack - Compute API nova-api : supports OpenStack Compute API, Amazon's EC2 API and a special Admin API nova-api-metadata : accepts metadata requests from instances Computing core nova-compute : creates and terminates virtual machine instances(KVM, qemu, XEN and etc) nova-schedule : schedule the VM to run on a host nova-conductor : “mediator” between nova-compute and the database 資訊技術服務中心

12 Networking for VMs nova-network : setting up bridging interfaces or changing iptables rules -> quantum nova-dhcpbridge : tracks IP address leases and records -> quantum Console Interface nova-consoleauth : authorizes user’s tokens that console proxies provide nova-novncproxy : provides a proxy for accessing running instances through a VNC connection Image Management (EC2 scenario) Web dashboard 。 OpenStack – Compute(Cont.) 資訊技術服務中心

13 Image Management (EC2 scenario) nova-objectstore : provides an S3 interface for registering images onto the image management service euca2ools client : euca2ools can be used to issue cloud management commands Command Line Interpreter/Interfaces nova client nova-manage client Queue service : RabbitMQ Database : sqlite3, MySQL and PostgreSQL 資訊技術服務中心 OpenStack – Compute(cont.)

14 OpenStack – Object Store 資訊技術服務中心 Swift Distributed file system and prevent any single point of failure swift-proxy-server) accepts incoming requests via the OpenStack Object API or HTTP

15 資訊技術服務中心 OpenStack – Image Store glance-api accepts Image API calls for image discovery, image retrieval and image storage glance-registry stores, processes and retrieves metadata about images (size, type, etc.) A database to store the image metadata sqlite3, MySQL and PostgreSQL image repository Swift, normal filesystems, RADOS block devices, Amazon S3 and HTTP

16 OpenStack – Identity 資訊技術服務中心 keystone handles API requests as well as providing configurable catalog, policy, token and identity services pluggable backend LDAP or SQL and Key Value Stores

17 OpenStack – Network 資訊技術服務中心 quantum-server accepts API requests and then routes them to the appropriate OpenStack Networking plugins for action Networking plugins and agents Plugins : Cisco virtual and physical switches, Nicira NVP product, NEC OpenFlow products, Open vSwitch, Linux bridging and the Ryu Network Operating System Agents : L3 (layer 3), DHCP (dynamic host IP addressing)

18 OpenStack – Block Storage cinder-api accepts API requests and routes them to cinder-volume for action cinder-volume maintain Cinder database state interacting with other processes (like cinder-scheduler) through a message queue access upon block storage cinder-scheduler picks the optimal block storage provider node to create the volume on

19 OpenStack – Dashboard Horizon Horizon is a modular Django web application that provides an end user and administrator interface to OpenStack services
