WHAT IS CLOUD COMPUTING ?
© Copyright © 2011, Oracle and/or its affiliates. All rights reserved.
Traditional Computing Environments Silos of hardware, storage, software & applications
• Sized for individual peak loads
– Inefficient and expensive
• Meet changing business needs?
– Inflexible and unresponsive
• Expensive to manage
– Too many moving parts
© Copyright © 2011, Oracle and/or its affiliates. All rights reserved.
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.

NIST Definition of
Cloud Computing v15
Cloud Computing Environments Reduced complexity & costs, higher quality of service
• Sized for Data Center
– Resource pooling
– High quality of service
• Meet changing business needs?
– Elasticity on-demand
– Rapid self service provisioning
• Easy to manage at lower cost
– Fewer moving parts

Many Cloud Use Cases

Private Cloud Public Cloud
New applications more often
than extensions to existing
Both dev/test and production
Enterprise more often then
departmental
More often used by
employees than external
users
Both stable and dynamic
workloads. Cloudbursting
rare.
Long-lived apps more often
than temporary

• Requires Hypervisor
– Works with single & clustered servers
• Supports heterogeneous OS
– Excellent isolation
• Low consolidation density
– Server and storage only
• Performance issues
– Hypervisor overhead
• Low ROI
– But, simple to implement
Hypervisor Hypervisor
Oracle VM 3.0 Application-Driven Virtualization
• High scalability – up to 128 vCPUs and 1 TB of memory per VM
• Manage of thousands of VMs from one console
• Policy-driven resource and power management
• Centralized network and storage configuration

• Requires Real Application Clusters
– Supports all Oracle applications
• Requires common OS
– Linux, Unix, Windows
• High consolidation density
– Servers, storage and OS
• Excellent performance
– No hypervisor overhead
• High ROI
– Especially using commodity hardware
Private Database Cloud Provision a Schema to a Shared Database
• Requires Real Application Clusters
– Extremely fast provisioning
• Requires common OS
– Least isolation
• Highest consolidation density
– Servers, storage, OS, database
• Excellent performance
– Fewest database instances
• Highest ROI
– But, requires application validation
