The Technology and the Business Side of Cloud
Cloud computing is a model for
enabling convenient,
on-demand network access to a
shared pool of configurable
computing resources (e.g., networks,
servers, storage, applications, and
services) that can be rapidly
provisioned and released with
minimal management effort or service
provider interaction.*

What IT Departments Need to Know
4
The IT department is in direct
competition with Off-Premise
alternatives for Lines of Business
funding
On-Premise
Some workloads require a level of
security, availability or government
compliance
Off-Premise
Some workloads might find Public
Cloud is good enough to do it justice at
a reasonable price
Traditional IT Private Cloud
Dedicated
Hybrid Cloud
Mixed
Public Cloud
Shared

OpenStack IBM Cloud x86-only
IBM is a platinum sponsor of
OpenStack Foundation
OpenStack open source code
can manage IBM compute,
network and storage resources
OpenStack supports x86,
POWER Systems and z System
mainframe
IBM offers Cinder interfaces on
most of its major storage
products and Swift interfaces for
object access
IBM Cloud is based on
OpenStack open source code,
with value-added proprietary
features from IBM
IBM Cloud Orchestrator and
IBM Cloud Manager with
OpenStack support a variety of
server hypervisors
IBM Spectrum Control™
provides reporting and
provisioning. IBM SmartCloud
Cost Management provides
chargeback capabilities
VMware and Microsoft are
entirely proprietary, but have
large market share for x86-
based server infrastructure
IBM was VMware’s first OEM
and joint development partner
(since 1998). IBM Global
Services is one of VMware’s
largest customers

Cloud Storage Taxonomy
Reference Storage
• Archives
• Images/Video
• WORM/NENR
Ephemeral Storage
• Typically boot volumes,
page files and temporary data
• Goes away when VM
is shutdown
Persistent Storage
• Persists across
VM reboots
• Can be shared
between VMs
• Transactional
• High Performance
Storage as the Storage CloudStorage for Compute Cloud
Hosted Storage
• File and Object access
• File Sync & Share
• Backup/Disaster Recovery

Cloud Storage Overview
Block
File
Object
Archival
Online
Ephemeral
Persistent
• Block storage offerings are differentiated by speed/throughput (as measured in
IOPS) and segmented by lifecycle of the disk. Device location does not matter.
• Ephemeral storage is tied to the lifecycle of a single VM (i.e. it is provisioned
when the VM is provisioned and destroyed when the VM is destroyed)
• Persistent storage has a lifecycle independent of any single VM and can be
provisioned/destroyed at any time and attached/detached to many VMs during it’s life
• File-based offerings are uncommon among providers, especially among those
targeting cloud native applications
• Primarily targeted at cloud enabled workloads
• Usage is being replaced in new application development with online object
storage
• Object storage offerings are differentiated by the durability of the data (i.e. odds of
irrecoverable loss) and segmented by the availability of the data (i.e. time required
to retrieve)
• An object in online storage is immediately accessible
• An object in archival storage may require minutes to hours to be accessible
