OpenStack
Created in 2010 by NASA & RackSpace Licence Apache 2.0 Manage IaaS Open-Source Framework API, Plugins, Drivers Multi-tenancy, Scalable, multi-plateform Developed in Python
* Infrastructure as a Service
OpenStack in the IaaS*

IaaS Components OpenStack Projects
Nova(Virtual Machines)
Swift(Object Storage)
Cinder(Block Storage)
Quantum(Virtual Networking)
Download it : http://goo.gl/01Dr5 Ubuntu 12.04 with Cloud Archives root / password MySQL installed Scripts already in /root Packages downloaded, NOT installed Usable with VMware & Virtual Box
Get the VM
Architecture
1 NIC for Management (192.168.0.0/24) → « NAT »
1 NIC for Data (10.10.10.0/24) → « Internal »
1 NIC for Public (7.7.7.0/24) → « Bridge » with WLAN or Ethernet
Networking
MySQL (Backend Databases) → Used by Keystone, Glance, Nova,
Cinder, and Quantum.
RabbitMQ (Middleware for queuing) → Used by Glance, Nova, Cinder and
Quantum.
Common Services
Identity (Users, tenants, roles, metadata) → Can be backed by LDAP
Token : Authentify requests from user / tenant Service Catalog : Endpoint registry Policy Services : Rule-based authorization engine
Keystone : Identity as a Service 1/2
1) Install packages & Configuration
2) Synchronize the Database
3) Create Users, Tenants, Roles
4) Create Services and Endpoints
5) Test the identity.
Keystone : Identity as a Service 2/2
Discovering, Registring, Retrieving Virtual Machine images. The images can be stored in : regular FS, RBD (Ceph), Amazon S3 or Swift. Disk Formats : raw, vhd, vmdk, vdi, iso, qcow2, aki, ari, ami. Container Formats : bare, ovf, aki, ami, ari.
Glance : Image Delivery 1/2
Glance : Image Delivery 2/2
1) Install packages & Configuration
2) Synchronize the Database
3) Import CirrOS image with CLI
Formerly « nova-volume » Create / Delete / Attach / Detach volumes to a VM Storage backed by : NFS, iSCSI, SolidFire, NetAPP, etc...
Cinder : Block Storage 1/2
Cinder : Block Storage 2/2
1) Prepare the second disk with LVM2) Install packages & Configuration3) Synchronize the Database4) Create a 1GB volume for testing
Provides connectivity to Vms Manage L2 & L3 with an API Networking backed by plugins : Open-vSwitch, Linux Bridge, Cisco, OpenFlow (BigSwitch, Floodlight, NEC, Ryu, etc), Midonet (Midokura) and NVP (Nicira / Vmware).
Quantum : Networking 1/2
Quantum : Networking 2/2
1) Install packages & Configuration2) Create virtual L2 with Open-vSwitch3) Create virtual L3 with the script4) Configure L3 Agent
Manages Virtual Machines Libvirt friendly Hypervisors supported : KVM / qemu, Xen, Hyper-V (all ready for production) Interact with other services (Cinder, Quantum, Glance, Keystone, etc)
Nova : Compute Service 1/2
Nova : Compute Service 2/2
1) Install packages & Configuration2) Synchronize the Database3) Configure the Hypervisor4) Spawn a VM with CLI
Developped with Python / Django Manage VMs, Images, Identity, Volumes Not yet full-integraded with Quantum : only L2 is working. L3 should be managed from CLI.
Horizon : Dashboard 1/2
Horizon : Dashboard 2/2
1) Install the packages
2) Connect to the dashboard : → http://<ip>/horizon
Use demo tenant / user Check networking before Spawn a VM from CirrOS image Attach the virtual port to a floating IP (from Quantum CLI) Ping the VM SSH the VM Play with volumes
Start your first VM !
