I.T. Challenges in Enterprise Businesses

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 ITDriven by IT “Consumerisation”

Application demands are becoming more complex

Application infrastructure is becoming more diverse

IMMEDIATE PERVASIVE AWARE

CLOUD MOBILE INTERNET OF THINGS

BIG DATA AUTOMATION ABSTRACTION

Application Development is Changing in Response

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

What is OpenStack?

Cloud Infrastructure For Cloud-Enabled Workloads

● Modular architecture● Designed to easily scale out● Based on (growing) set of core services

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

● 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?

WHY RED HAT ?

OpenStack: Framework for the Cloud

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

Red Hat Enterprise Linux OpenStack Platform

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

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?”

Red Hat's OpenStack LeadershipWhy 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

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

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

AM I READY FOR OPENSTACK ?

Virtual Machine Workload TypesTRADITIONAL

(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

Scaling storage with traditional, proprietary appliances:

Scaling storage with standard x86 servers & disks:Capacity grows incrementally

● Predictable, efficient

One server vendor for storage & compute

● Simplifies procurement & support● Increases purchasing power

Capacity grows an appliance at a time

● Large one-time investment● Disruptive “forklift” upgrade

Specialised, expensive hardware● Cost & capacity don’t scale evenly
