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
11
資訊技術服務中心
OpenStack – Compute(Cont.)

Networking for VMs



Console Interface



nova-network : setting up bridging interfaces or
changing iptables rules -> quantum
nova-dhcpbridge : tracks IP address leases and
records -> quantum
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。
12
資訊技術服務中心
OpenStack – Compute(cont.)

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
13
資訊技術服務中心
OpenStack – Object Store

Swift


Distributed file system and prevent any single point of
failure
swift-proxy-server) accepts incoming requests via the
OpenStack Object API or HTTP
14
資訊技術服務中心
OpenStack – Image Store

glance-api


glance-registry


stores, processes and retrieves metadata about images
(size, type, etc.)
A database to store the image metadata


accepts Image API calls for image discovery, image
retrieval and image storage
sqlite3, MySQL and PostgreSQL
image repository

Swift, normal filesystems, RADOS block devices,
Amazon S3 and HTTP
15
資訊技術服務中心
OpenStack – Identity

keystone


handles API requests as well as providing configurable
catalog, policy, token and identity services
pluggable backend

LDAP or SQL and Key Value Stores
16
資訊技術服務中心
OpenStack – Network

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)
17
OpenStack – Block Storage

cinder-api


cinder-volume




accepts API requests and routes them to cinder-volume
for action
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
18
OpenStack – Dashboard
