I.T. CHALLENGES

WORKLOADS ARE EVOLVING
TRADITIONAL 
WORKLOADS
!
● Typically resides on a single large  
Virtual Machine
● Cannot tolerate any downtime
● Needs expensive high availability tools 
found in VMware vSphere
● Application scales up rather than out
CLOUD 
WORKLOADS
!
● Workload resides on multiple Virtual
Machines
● Tolerates VM failure – if one fails, another
quickly replaces it
● Fault tolerance often built into workload
● Application scales out rather than up

CHALLENGES WITH A  
TRADITIONAL INFRASTRUCTURE
● Our data is too large
● We're producing vast amounts of data, exponentially!
● Way past the ability of traditional systems & applications
● Scaling UP no longer works. Scaling OUT is a necessity 
● Service requests are too large
● More and more client devices coming online
● Much harder to maintain service to customers 
● Applications weren't written to cope with demand

WHAT IS OPENSTACK?

OPENSTACK 
CLOUD INFRASTRUCTURE FOR  
CLOUD-ENABLED WORKLOADS
● Modular architecture
● Designed to easily scale out
● Based on (growing) set of core services

Ecosystem of hardware and software

WHY OPENSTACK
● Brings public cloud-like capabilities into your datacenter
● Provides massive on-demand (scale-out) capacity
● 1,000's → 10,000's → 100k's of VMs
● It's OPEN!
● Provides flexibility to customize and interoperate
● Community development = higher “feature velocity”
● Features and functions you need, faster to market over
proprietary software

● 65% of respondents have deployed or
are planning to deploy OpenStack®
!
● 62% of respondents plan to use
OpenStack for a private cloud
infrastructure
!
● 42% of respondents need OpenStack for
massive scalability

WHY RED HAT?

OPENSTACK 
● Needs to access x86 hardware resources
● Needs an operating environment, hypervisor, services
● Leverages existing code libraries for functionality

OPENSTACK 
● It is dependent on the underlying Linux...
LINUX

OPENSTACK PLATFORM 
OPTIMIZED FOR AND CO-ENGINEERED WITH RED HAT ENTERPRISE LINUX

THE IMPORTANCE OF INTEGRATION WITH LINUX...
● A typical OpenStack cloud is made up of at least 10 core
services (Nova, Cinder, Keystone, Neutron, glance, etc) +
plugins to interact with 3rd party systems – eg. storage
arrays, network switches.
● These services run on top of a Linux distribution with a
complex set of userspace dependencies, requiring tight
integration
● A supported, stable platform requires integration and
testing of each of the components

● Many of the most complex features are provided by Linux
with OpenStack providing management and orchestration
● For example: virtualization provided by the KVM hypervisor, with
libvirt management interface, interacting with Open vSwitch
userspace switch, transitioning to the kernel's networking stack to
handle network namespaces – Each potentially managed by different
OpenStack services.
● These components need to be engineered & productized
together
● OpenStack cannot be productized as a layered product

● Examples of RHEL optimized enablers for OpenStack:
● Virtualization – guest performance, reliability, and Windows
● Security - SELinux enforcing guest isolation
● Network – SDN/OVS performance optimized
● Storage – vendor plugins, performance, thin provisioning
● Ecosystem – certification of hardware, storage, and networks
!
● The pairing of the Linux operating system and OpenStack is so tight
that Red Hat Enterprise Linux OpenStack Platform is the only
combination that can most effectively support functionality,
performance, security, system-wide stability, and ecosystem support

HOW DO WE GET FROM
COMMUNITY OPENSTACK TO
RED HAT OPENSTACK?

RED HAT LEADS THROUGH OPEN INNOVATION

OPENSTACK RELEASE CADENCE
● Upstream
● Source code Only
● Releases every 6 month
● 2 to 3 'snapshots' including bug fixes
● No more fixes/snapshots after next release
● RDO
● Follows upstream cadence
● Delivers binaries

OPENSTACK RELEASE CADENCE
● Red Hat Enterprise Linux OpenStack Platform 5
● 6 Month cadence
● Roughly 2 to 3 months AFTER upstream
● Time to stabilize, certify, backport etc.
● Increased to 3 year lifecycle
● e.g., Support for Havana ends after “K” release
● Will continue to increase lifecycle over time
● Based on upstream stability and resources

HOW DO I KNOW IF I AM
READY FOR OPENSTACK?

VIRTUAL MACHINE WORKLOAD TYPES
TRADITIONAL
(RHEV)
CLOUD
(OpenStack)
MIXED/HYBRID
Big stateful VM Small stateless VMs Combination of Traditional
and Cloud VMs to provide
application. Database may
be hosted on traditional
workloads, web front-end
and logic layers on cloud
workloads.
1 Application → 1 VM 1 Application → Many VMs
Lifecycle in years Lifecycle hours to months
Scale up (VM gets bigger) Scale out (add VMs)
Not designed to tolerate
failure of VM, so you need
features that keep VMs up
If a VM dies, application kills
it and creates a new one, app
stays up
Application SLA requires
enterprise virtualization
features (migration, HA, etc.)
to keep applications
available
Application SLA requires
adding/removing VM
instances to application
cloud to maintain application
availability
