RED HAT ENTERPRISE LINUX OPENSTACK PLATFORM

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 “Consumerization”


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 datacenter

● 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

customize and interoperate● Community development = higher “feature velocity”

● Features and functions you need, faster to market over proprietary software


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

● Optimized 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 productized 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?”

Installation & Stability

● Intuitive “wizard-style” graphical installer

● Ensures a production-ready environment

● Enables high availability (HA) across controller and compute nodes (including networking in “active-active”)

● Automatically Utilizes Fencing as containment mechanism

● Includes Ceph client support for storage backends

● Supports multiple Cinder storage volume setup/config● Optional support for Cisco Nexus 1000v


Red Hat Enterprise Virtualization 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 virtualized Linux

VMware vSphere*vCenter Driver

● Co-exist with existing infrastructure assets

● Provides a seamless path to future migration to OpenStack

● Uses NSX1 plugin for Neutron

1NSX is only supported in production environments, per VMware's support requirements

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

PETS

CATTLE

Credit : Tim Bell @ Cern Labs

Pets are given names like pussinboots.cern.ch

They are unique, lovingly hand raised and cared for

When they get ill you nurse them back to health

Cattle are given numbers likevm0042.cern.ch

They are almost identical to other cattle

When they get ill you get another one


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 virtualization

features (migration, HA, etc.) to keep applications available

Application SLA requires adding/removing VM

instances to application cloud to maintain application

availability
