What is OpenStack?
Set of Open Source Software tools for building cloud computing platforms
A Technology Framework (Not a product in itself) Provides Public Cloud-like capabilities inside your
datacenter Overseen by the OpenStack Foundation
Technical Committee Board of Directors User Committee Individual Members Sponsored by Companies (like Red Hat and others)

Why use OpenStack
Technical Reasons Enable very large clusters Choose technology vendors of choice Benefits of Open Source
Business Reasons Enable Business Agility (faster time to market) Autonomy for development teams Enable cloud-ready applications Bring 'shadow it' back in house Transform the business

OPENSTACK OVERVIEW
Modular architecture Designed to scale out Based on (growing) set of core services Needs an operating environment, hypervisor, services

I want a VM!
Please authenticate
with your credentials!!

Ok, we need to
find a place to build this VM.
Nova
Tag - youre it!
NovaNeutron, please
set up the network for a
new VMNeutron
I've enabled Network
policy for your VM, Heres
your interface
Cinder, please create a block device for the
VM
Nova
Created! Dont forget to mount it!

PackStack: Installation
Red Hat developed OpenStack installer for RPM-based Linux Distributions
Deployment options Interactively Answer file Quick Start All-in-one
Features Single-host install Multi-host install RHOS, RDO, EPEL Fedora, CENTOS, RHEL

Packstack Demo
Add a compute node to an existing all-in-one single-node cluster
Modify packstack answers file Modify EXCLUDE_HOSTS to ignore the existing host Add the new host to CONFIG_COMPUTE_HOSTS Rerun packstack

WHILE WE WAIT FOR PACKSTACK .... WHAT'S NEW IN VERSION ICEHOUSE NOVA
OpenStack Compute (Nova) Limited live upgrades. Enables upgrade of controller infrastructure and
subsequently upgrade individual compute nodes without requiring downtime
Libvirt (KVM) driver updates Improved scalability and performance with VirtIO SCSI (virtio-scsi)
instead of VirtIO Block (virtio-blk) for block device access Virtio RNG device provides increased entropy
Scheduler now supports server groups using anti-affinity and affinity filters
Libvirt driver now includes watchdog support to automatically trigger guest lifecycle actions, in the event of a kernel panic or other system crash

WHILE WE WAIT FOR PACKSTACK .... WHAT'S NEW IN ICEHOUSE NEUTRON
OpenStack Networking (Neutron) Improved performance with new ML2 plugin for new L2 networking
technologies (SR-IOV PCI passthrough). Simplifies mixing networking infrastructure and plugins
New plugins for OpenDaylight, Nuage, IBM SDN-VE, OneConvergence Load-Balancing-as-a-Service drivers: Radware, NetScaler, Embrane Cisco CSR VPN driver support New Red Hat certification program for networking plugins

WHILE WE WAIT FOR PACKSTACK .... New Core Project (Incubating) SAHARA
OpenStack Data Processing (Sahara) Provisioning and management of Hadoop
clusters Help identify and improve utilization of unused
compute power from general purpose OpenStack IaaS cloud
Pluggable system of Hadoop installation engines for different distros
Predefined templates of Hadoop configurations with ability to modify parameters.
