The document presents a pragmatic approach to cloud computing, emphasizing the need for organizations to align their cloud strategy with business objectives while considering architectural design and service provider selection. It covers key transformations, integration approaches, and the importance of defining roles within cloud operations. Additionally, the document outlines Oracle's cloud architecture framework and provides insights into the implementation of both public and private cloud services.

2. 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.

4. Agenda
What are the key considerations in Cloud
architecture? Consider….
• What is your cloud ‘perspective’?
• What sort of architecture do you need?
• What is the focus of component architectures?
• What are the ‘Deployable Entities’?
• How to think about ‘refactoring’ the
organization?

5. Contrasting two approaches
This presentation emphasizes ‘integration’
- Virtualization Centric
• Has a potential of increasing
complexity over time
vs.
- Integration Centric
• Integration & architectural abstraction
offers higher performance and
greater ‘simplicity’

6. Before we get started….
What is your cloud ‘perspective’?
© 2011 Oracle Cloud Computing – Why you need Architecture 6

7. What’s your Cloud ‘Perspective’?
- Three differentiating criteria
- This perspective drives your decisions
Motivation Pure $ savings vs. Business Agility
Project
IT Dept. vs. Business
Control
Business
IT as Support vs. IT as a Business
Model
Is your cloud project ‘cutting costs’ or ‘driving business’?
© 2011 Oracle Cloud Computing – Why you need Architecture 7

8. How does ‘perspective’ affect approach?
Focus on the areas key to your initiative
Business agility
Consider the Oracle Cloud Maturity Model
• 8 domains (not all may be relevant to initiative)
• Multiple uses:
1. Framework for insight and discussion
2. Diagnostic for current environment Business
Architecture &
3. Planning tool / roadmap generator Strategy
4. Program longitudinal measurement tool
Information Organization
• Select key capabilities to focus on …
Infrastructure Governance
Operations Services
IT cost savings

9. Key Business / IT Transformations
Define your key transformations
Traditional Approach Cloud Approach
Systems and application The cloud ‘control plane’ is
management is specific to architected as a model centric
select systems & apps service
Operations developed IT will move to building up-
and performed by the IT front operational functions for
department a self-service model.
Architecture implemented Build infrastructure up-front,
up front (early binding) deploy later (late binding)

10. What sort of cloud architecture
do you need?
© 2011 Oracle Cloud Computing – Why you need Architecture 10

11. Why do I need an Architecture?
Focus on the key decisions
• “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.)
• “in the end, architecture boils down to whatever the
important stuff is.” (Martin Fowler)
• Architecture is key to avoiding Black Swans

12. Oracle Cloud Conceptual Architecture
Outline and group the basic elements
• Key elements
- Service model
- Management
infrastructrue
- Resources
- Roles –
Consumer,
Broker,
Auditor…

13. Drill down for critical functional detail
e.g., cloud management

14. Map to technologies / products
Including standards and portability

15. Cloud Logical Architecture
Consider key relationships, abstractions…

16. Key abstractions – Making ‘IT’ Simple
Architecture concepts and Portability issues
APIs
Separation of roles Code deployment,
(e.g., Cloud Provider developer discovery and
vs Service application control
Developer)
Deployable Entities Images
(aka VDCs) include Application and data
Service Templates deployment
and Context (e.g.
‘Assemblies’)
Separation of Model

23. Absracting application architecture
What are Deployable Entities?

24. What will you ‘deploy’?
It’s more complex than a bunch of images
Deployable Entities
(aka VDCs) include Model Mgmt.
Service Templates Architectural models of
and Context (e.g. cloud applications may
‘Assemblies’) be external (deployment
code), embedded (e.g.
OVF) or internal

25. Oracle Cloud API ‘Service Catalogue’
Images plus architectural meta-data
• Repository of models
• Models contain
templates and
service contracts
- Payloads like virtual
server images
- Application metadata
such as configurations
and policies
© 2011 Oracle Cloud Computing – Why you need Architecture 25

26. Model / Service Management
Need to do both
• 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

use and re-use of cloud

• 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

• But are ‘private’ clouds 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
• How ‘SELF’ is self-service really?
- What roles are involved in managing, deploying and consuming
the Cloud?

34. So how do I get there?
Use architecture to keep IT simple

35. 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

36. 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 initiatives.
• It doesn’t have to get more complicated
- Before you start (not just after you finish)…. Architecture
- Make things more simple through higher levels of integration and
abstraction
