This document presents a pragmatic approach to cloud adoption, emphasizing the importance of aligning IT standardization with specific business drivers. It outlines Oracle's cloud reference architecture, key considerations for implementation, and the criteria for selecting cloud service providers and technologies. The focus is on transformations in both IT and business practices to successfully adopt a cloud strategy.

4. Agenda
Key considerations to Cloud implementation?
Consider….
• What forces drive your adoption of Cloud?
• What sort of architecture do you need?
• The focus of component architectures?
• What are the ‘Deployable Entities’?
• How will you ‘refactor’ the organization?

5. Before we get started….
What forces influence Cloud adoption?

6. What Forces influence your Cloud Adoption?
- Consider three differentiating criteria
- This perspective drives your decisions
Business Drivers Pure $ savings vs. Business Agility
Project Control IT Dept. vs. Business
Business Model IT as Support vs. IT as a Business
Is your cloud project ‘cutting costs’ or ‘driving business’?

7. How Do Forces Affect Approach?
Select tools to support your initiative Business agility
The Oracle Cloud Maturity Model…
o Framework for insight and discussion
o Diagnostic for current environment
o Planning tool / roadmap generator
o Measure long-term improvement
• Focus on select domains IT cost savings

8. Define Your Key Transformations
Include both IT & business transformations
Traditional Approach Cloud Approach
App / system specific Model centric control plane
management
Operations developed and IT ‘architects’ operations for
performed by IT consumer self-service
Architecture implemented Build infrastructure up-front,
up front (early binding) deploy later (late binding)

9. Consider an Architecture Strategy
This presentation emphasizes ‘integration’
– Virtualization Centric
• Potential of increasing complexity
over time
vs.
– Integration Centric
• Integration & architectural abstraction
offers greater performance & ‘simplicity’

12. Why build an Architecture?
“architecture encompasses the set of significant
decisions about the organization of a software
system including the selection of the structural
elements and their interfaces by which the system
is composed; behavior as specified in collaboration
among those elements; composition of these
structural and behavioral elements ……” (Krutchen,
Booch, et.al.)

13. Start with Cloud Conceptual Architecture
Outline and group the basic elements
• Key Elements
– Service model
– Management

23. Abstracting application architecture
What are Deployable Entities?
23 Copyright © 2012, Oracle and/or its affiliates. All rights

24. Use a Logical Architecture
Key relationships and abstractions
24 Copyright © 2012, Oracle and/or its affiliates. All rights
reserved.

25. Use a Logical Architecture for Key Abstractions
e.g., What will you deploy (it’s more than simple images)
Role separation APIs
Deployable Entities Images
(‘Assemblies’) include
Service Templates and
Context (aka VDCs) Model Mgmt.
Architectural models
may be external,
Control Separation embedded, or
internal
Services
Logical resources
Data
25 Copyright © 2012, Oracle and/or its affiliates. All rights

26. Oracle Cloud API ‘Service Catalog’
Images plus architectural meta-data
• Repository of models
• Models contain templates
and service contracts
– Payloads e.g., virtual server
images
– Application metadata such as
configurations and policies
• Key components of Oracle’s
Cloud API standards
26 Copyright © 2012, Oracle and/or its affiliates. All rights

27. Model / Service Management
Need to do both
• Model management (build-time) • Service management (run-time)
– Exposes resources to developers – Capacity management
– Stores developer’s models – Service management
• Developer’s main point of • Operator’s main point of contact
interaction with the cloud for the cloud
• Defines services • Provisions resources
• Includes solution catalog • Includes configuration repository
(deployable entities) (current state)

Automating deployment of ‘assemblies’

Dev/Test Environment (VM Templates +

relationships & start
order Metadata
• 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 instance has well-contained configuration parameters for flexibility

• Consider Self Service
– Public developer cloud – provisioned in minutes, but no controls or corporate
governance
– Enterprise private cloud – need controls, standards, prioritization, etc.
… Enterprise cloud – Faster to deploy than traditional IT, but slower than public cloud
• How ‘SELF’ should self service be?
– Who does what?

36. In Summary, ….And What’s Next
Use architecture to keep IT simple

37. Focused Implementation Vs. Wide Diffusion
Most companies have multiple projects underway or anticipated
• Strategic – Complete migration for a given architecture/application, often focusing on revenue
enhancement
• Tactical – Wide deployment of a limited technology (e.g. virtualization), often focusing on cost reduction

38. Cloud Computing Roadmap
How will your Cloud be introduced?
• Most companies have multiple initiatives.
• It doesn’t have to get more complicated
- Architecture – Before you start…
- Integration – Make things simple
- Technology – Oracle VM Templates, OVAB Assemblies,

48. A Pragmatic Approach to Cloud Computing
Abstract
As organizations adopt cloud computing, they need to define an
approach that matches the combined advantages of IT
standardization, consolidation, and self-service, with their specific
business drivers. This session outlines Oracle's Cloud Reference
Architecture and outlines fundamental considerations to
implement a cloud strategy. Methods are presented for aligning
critical architectural decisions and key organizational
transformations with cloud strategy, as well as the important
criteria to consider when selecting cloud service providers and
cloud enabling technologies.
