3. I.T. Challenges in Enterprise Businesses

4. EXISTING EMERGING
● Dynamic applications that scale to
meet demand
● Open source is well understood and
widely adopted
● Software-defined infrastructure
across compute, networking,
and storage
● Compressed innovation cycle
● IT as a competitive advantage
● Applications with predictable
usage models
● Open source perceived as
unknown and risky
● Compute-centric infrastructure
● Long innovation cycle
● IT as a cost center
Seismic Shift in Enterprise IT
Driven by IT “Consumerisation”

5. Application demands are becoming more complex
Application infrastructure is becoming more diverse

BIG DATA AUTOMATION ABSTRACTION
Application Development is Changing in Response

6. 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
● Mobile phones, tablets, etc.
– Much harder to maintain service to customers
● Applications weren't written to cope with demand

7. What is OpenStack?

8. Cloud Infrastructure For Cloud-Enabled Workloads
● Modular architecture
● Designed to easily scale out
● Based on (growing) set of core services

9. Why OpenStack?
● Brings public cloud-like capabilities into your data-centre
● Provides massive on-demand (scale-out) capacity
– 1,000's → 10,000's → 100k's of VMs
● Removes vendor lock-in
– Open source provides high-degree of flexibility to
customise and interoperate
● Community development = higher “feature velocity”
– Features and functions you need, faster to market
over proprietary software

10. ● Top OpenStack Priorities
● 44% Increased emphasis on
certified hardware
● 44% commercial OpenStack support
● 43% integration with open source
management initiatives

What Role Does OpenStack Have in Your Cloud
Strategy?

11. WHY RED HAT ?

12. OpenStack: Framework for the Cloud
● Needs to access x86 hardware resources
● Needs an operating environment, hypervisor, services
● Leverages existing code libraries for functionality

13. Red Hat Enterprise Linux OpenStack Platform
● It is dependent on the underlying Linux
● Optimised and Co-Engineered with Red Hat Enterprise Linux

14. A typical OpenStack cloud is made up of at least 9 core
services + plugins to interact with 3rd party systems
● These services run on top of a Linux distribution with a
complex set of user space integration dependencies
● OpenStack cannot be productised as a stand alone layer
● A supported, stable platform requires integration and
testing of each of the components
“If your Windows virtual machine hosted by a KVM hypervisor
running on an IBM blade, connecting to an EMC storage array
through an Emulex HBA has issues with storage corruption,
who do you call?”

compute nodes (including networking in “active-active”)
– Automatically Utilises Fencing as containment
mechanism
● Includes Ceph client support for storage backends
– Supports multiple Cinder storage volume setup/config
● Optional support for Cisco Nexus 1000v

18. Red Hat Enterprise
Virtualisation Hypervisor
*Red Hat Enterprise Linux KVM
● Lightweight / small footprint
● Less overhead
● Smaller attack surface
● Cost effective
● Closer to operating system DNA
● Provides massive scale-out capabilities
● Maximum benefit with virtualised Linux
VMware vSphere
*vCenter Driver

25. Red Hat's OpenStack Leadership
Why Do These Statistics Matter?
● Proof that with Red Hat's near 20 year history in open source,
we have the experience and resources to:
● Support production-ready customers globally
● Drive new features
● Influence strategy and direction of project
● Enable partner collaboration
● Wide ranging participation, contrasts with most others who are
more narrowly focused
● All of these efforts allows us to create an enterprise-grade
distribution with ecosystem, lifecycle, and support that
customers expect from Red Hat

28. OpenStack Release Cadence
● Upstream
– Source code Only
– Releases every 6 months
– 2 to 3 'snapshots' including bug fixes
– No more fixes/snapshots after next release
● RDO
– Follows upstream cadence
– Delivers binaries

29. OpenStack Release Cadence
● Red Hat Enterprise Linux OpenStack Platform
– 6 Month cadence
– Roughly 2 to 3 months AFTER upstream
● Time to stabilise, certify, backport etc.
– 3 year “production phase” lifecycle
● e.g., Support for Juno ends at the “P” release
– Will continue to increase lifecycle over time
● Based on upstream stability and resources

30. AM I READY FOR
OPENSTACK ?

31. 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 virtualisation
features (migration, HA, etc.)
to keep applications available
Application SLA requires
adding/removing VM
instances to application cloud
to maintain application
availability

issues which have shut down the
running VM.
o This feature is provided via tight
integration between multiple Red Hat
products, like RHEL, RHEL High
Availability Add-On and RHEL OSP.
