The document is a presentation on cloud computing by Dr. James Baty, VP of Oracle Global Enterprise Architecture Program. It discusses key concepts in cloud computing like standardization, deployable entities, refactoring development and operations roles, and building a roadmap to the cloud. It provides examples of moving applications to the cloud, private database cloud architectures, and engineered systems in the cloud.

4. Moving to Cloud
First Inventory Applications & Workloads
Suitable for cloud now Not as suitable for cloud
Time based Vertically scaled applications
Very parallel (i.e. batch) Consistent load levels
Spiky traffic Latency sensitive applications
Capital intensive (especially Insecure applications
startup)
Hardware device dependent (e.g.
Proof of Concept fax server, SNA gateway)
Low utilization ISV unsupported
Less deployment costs Per CPU licensed applications
High bandwidth costs / high real
estate

5. What Do You Want the Cloud to Do?
Start with Common Use Cases
Augmentation
(Elastic scaling)
Shared Services
Development
and Test
Resource sharing
(consolidation)
Most enterprises are trying
• Shared development and test environments
• Hardware & Services consolidation

6. Shared Services – Many Possibilities
Shared • Sharing Applications across org
Functions • Enabled by SOA, BPM
Java PaaS • Build & deploy to common platform
• Enterprise Private Cloud
Shared SOA • Application services integration
X X • Centralized authorization for
Shared Security X all apps
X X XX
DBaaS • Rapid access to all enterprise data
• Parallel Processing of Transactions

9. Database Cloud Planning
Identification of Applications to Migrate
- New applications are deployed to the Cloud
- Existing applications are migrated based on:
• Difficulty
• ROI
• Suitability
- The benefits and difficulties of consolidating existing
applications in the Cloud will vary
• Applications with highly varying peaks will show
greatest benefit
- The “lowest hanging fruit” should be migrated to the
Cloud first

17. Service Catalogue
• Repository of models
• Models contain
templates and
service contracts
- Payloads like virtual
server images
- Application metadata
such as configurations
and policies

18. Model / Service Management
• Model management supports • Service management controls
build-time functions in cloud the run-time aspects of the cloud
- Exposes resources to developers - Capacity management
- Stores developer’s models for - Service management
deployment
• Operator’s main point of contact
- Validates cloud models
for the cloud
• Developer’s main point of
• Provisions / monitors resource tier
interaction with the cloud
• Contains configuration
• Model management also
management repository which is
contains the solution catalogue,
the current state of all cloud vDCs
facilitating discovery, storage,
use and re-use of cloud services

• Package up complex structure from dev/test and reconstitute in production
• Minimize setup time and risk of hard-to-debug configuration errors
• Easily replicate in production with minor variations
• Each production instance has well-contained configuration parameters for
flexibility

26. Cloud Computing Readiness
May Require Diverse Business Changes
 Consider, for example, IT governance & risk management,
information modeling & ownership, operations & service
management.
 How are these areas managed today?
• identified responsibilities, documented processes, etc.
 Do you have a mechanism for assessing capabilities in
each area?
 How will you identify needs for changes or improvements
to support cloud computing?
© 2011 Oracle Cloud Computing – Making IT Simple 26

27. Example Cloud Capabilities by Domain
Areas Important to Cloud Readiness
 Reference architecture  Business & IT drives
 Standards  Costs & Benefits
 Model templates  Executive sponsorship
 Data ownership  Roles & responsibilities
 Model packaging
 Risk management
 Service monitoring
 Cloud change management
 Capacity management  Services portfolio management
 Operational tools & processes  Services engineering approach
• To succeed at Cloud services adoption, an organization must
adequately progress in all the appropriate domains.

28. Cloud Computing Roadmap
How Will Your Cloud Be Introduced?
Cloud computing efforts range from small ‘experiment’
projects to major strategic initiatives.
Most companies have multiple projects underway or
anticipated.
• Separate from the new architecture, is there a plan for
how the new model will be rolled out?
• E.g., by application, by business unit, by geography…
• Is cloud viewed as a limited tactical deployment, major
strategic initiative, or both?

• Tactical – Wide deployment of a limited technology (e.g. virtualization),
often focusing on cost reduction

30. Key Business/IT Transformations
Current Approach Cloud Approach
IT Architecture designed Build infrastructure up-front,
up front (early binding) deploy later (late binding)
IT operations developed IT will move to building up-
and performed by the IT front operational functions for
department a self-service model.
Systems and application The cloud ‘control plane’ has
management was specific to be architected as a general
to select systems and service
applications

• But private clouds are different from public clouds…
- E.g., On-demand self service
• Public developer cloud – unrestricted resources provisioned in
minutes, but with no controls or corporate governance
• Enterprise private cloud – need provisioning controls, standards
enforcement, prioritization, approvals, etc.
- I.e., Enterprise cloud faster to deploy than traditional IT, but probably
slower that public cloud
• There are other criteria with similar differences
- Security, governance, high availability, global access ….
