OpenStack adoption
Red Hat Open Hybrid Cloud
Red Hat OpenStack Platform
Overview
Red Hat OpenStack Platform delivers an integrated and open foundation to
create, scale, and manage a secure and reliable public or private
OpenStack cloud.
Customer benefits:
Delivers a production-ready cloud platform that combines Red Hat’s hardened
OpenStack infrastructure
Co-engineered and integrated with Red Hat Enterprise Linux
Offers a telco-grade, massively scalable platform
Delivers the highest levels of OpenStack performance
OpenStack provides elastic and scalable
platforms
Managed Private
Cloud
A Managed Private cloud
is a compute platform
implemented on premise
under the control of the IT
department, with a
management framework to
bring flexibility across
various resource pools.
Software to manage
policy-based provisioning
and management of data
storage independent of
the underlying hardware.
Can use industry standard
servers and disks rather
than purpose-built or
proprietary appliances.
Software Defined
Storage
Telco/NFV
Provides a stable, robust
and scalable means for
Telco providers to detach
from current networking
equipment at a lower cost
that allows them greater
flexibility for future growth
needs
Hybrid Cloud
Hybrid cloud is a cloud
computing environment
which uses a mix of on-
premises, private cloud
and third-party, public
cloud services with
orchestration between the
two platforms.
OpenStack enables agile and responsive
Apps
Converged IaaS and PaaS
Develop, run, orchestrate, and
manage multi-container based
applications at cloud scale on a
private cloud platform based on
OpenStack.
Container Infrastructure
Integrated container
infrastructure platform built to run,
orchestrate, and scale container-
based applications (traditional and
cloud native) across a managed
cluster of container hosts
Container-based application
development platform
An extension of the container
infrastructure platform to include
developer tools, services,
workflows, automation, and
application lifecycle management
capabilities.

Main components
OpenStack Storage
OpenStack supports four types of persistent Storage:
-  Block storage (Cinder) Provides persistent block storage to running instances. Its
pluggable driver architecture facilitates the creation and management of block
storage devices.
-  Image Storage (Glance) - Stores and retrieves virtual machine disk images.
OpenStack Compute makes use of this during instance provisioning.
-  Shared File Systems (Manila) - provides a set of services for management of
shared file systems such as CIFS, NFS, CephFS & HDFS in a multi-tenant
environment.
-  Object storage (Swift) - Stores and retrieves arbitrary unstructured data objects via
a RESTful, HTTP based API. It is highly fault tolerant with its data replication and
scale out architecture. Its implementation is not like a file server with mountable
directories.
WHY TRADITIONAL STORAGE
SOLUTIONS WON'T WORK?
Storage challenges in OpenStack
Multiple storage interfaces to consume
File
Block
Object
They don’t all scale at the same pace
Mixing up storage technologies is painful to manage, needs
more talents/skills

Rising tide of software-defined storage
“By 2020, between 70-80% of unstructured
data will be held on lower-cost storage
managed by SDS environments.”
“By 2016, server-based storage solutions will
lower storage hardware costs by 50% or more.”
