Cloud Computing – a disruptive new paradigm

“Clouds will transform the information technology (IT) industry…profoundly change the way people work and companies operate.”

1990

2009Software as a Service

Utility Computing

Cloud Computing

Grid Computing

From Cloud user perspectiveEasy to consumePay per useStandardised offeringsRapidly delivered

From Cloud provider perspectiveVirtualised resourcesHighly automatedSimplified and standardisedElastically scalable (up/down)Near zero incremental costs

Disruptive Technology…high potential for disruption to IT or the business, the need for a major financial investment, or the risk of being late to adopt.




Cloud definitions

Defn: “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.”

Source: NIST Cloud definition v14: http://csrc.nist.gov/groups/SNS/cloud-computing/index.html

A user experience and a business modelCloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model

An infrastructure management and services delivery methodologyCloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they resemble a single large resource. This can then be used to deliver services with elastic scaling




Cloud Computing is a new consumption and delivery model inspired by consumer Internet services, that exhibits the following key characteristics:

IT Analysts:- Variable pricing- No long term commitments- Hosted, on-demand

provisioning- Massive, elastic scaling- Standard Internet technology- Abstracted infrastructure- Service-oriented

Financial Analysts:- Utility pricing- Hosted, service-based

provisioning- Parallel, on-demand processing- Scalable- Virtualized, efficient infrastructure- Flexible

Consumers:- Enhanced user experience- Flexible pricing / business models- On-demand provisioning- Unlimited scaling- Software developer platform- Flexible

Press:- Pay by consumption- Lower costs- On-demand provisioning- Grid and SaaS combination- Massive scaling- Efficient infrastructure- Simple and easy

Threat or opportunity for the CIO?

Some CIOs worry that Cloud will bring about disruptive change to IT operations

Business units sourcing ‘public clouds’ from external providers rather than ITDisintermediation of the traditional IT teamPerception of hype – ‘Client/Server all over again’

CIOs need to embrace the change, not resist it

Understand the benefits of cloud, as well as its drawbacksUnderstand the emerging capabilities of ‘public cloud’ providers and include these services in IT offerings, where it makes sense

With an IT strategy that embraces Cloud, CIOs can better satisfy their customers

Improves visibility of IT use - more responsive, simpler, cheaperIncreases range of services, applications, and capabilities available to business usersBUT.... Cloud requires an overall strategic vision with a pragmatic, evolutionary approach




Four major categories of Cloud Computing services are emerging

Infrastructure-as-a-Service

Platform-as-a-Service

Application-as-a-Service

Servers Networking Storage

Middleware

Collaboration

Financials

CRM/ERP/HR

Industry Applications

Définir une stratégie Cloud va répondre à de nombreuses questions :Nous utilisons un “framework », des modèles, des outils issus de la recherche pour aider nos clients à répondre à ces questions

Could we utilize Cloud services, and why ?

What types of services would be most appropriate ?

How would they support our business and IT objectives ?

Which Cloud services would align best with our role as IT service providers ?

What would be the likely benefits ?

Would our current IT infrastructure support Cloud service delivery (or not) ?

What specific IT improvements would we need to make ?

How can we develop a roadmap to achieve our Cloud objectives ?

Where do we start ?




3.1 Implementation Plan By Phase An interactive workshop is at the core of a sequence of activities leading to a cloud strategy and plan.

Pre-workshop callClient and IBM have a pre-workshop conference call toreview workshop details, logistics and begin the workshop scheduling process. IBM provides a pre-workshop data collection template.

Data collectionClient provides IBM with pre-workshop background material (4-5 pages of high-level information based upon the IBM-provided template)

Workshop preparationIBM prepares workshop materials based upon client-provided information

Client executiveworkshop

IBM facilitators and Client IT leadership members participate in a two (2) day structured workshop

Data analysis

IBM conducts analysis of information gathered in the workshop and creates a final report presentation

Clientpresentation

4 5 6 71 – 2 weeks elapse time

1 – 2 weeks elapse time

The 2-day client executive workshop is the key step within this strategy and planning engagement




Over the course of two days IBM uses a structured approach to identify potential cloud computing opportunities and to collect information that will enable us to develop a high-level cloud computing roadmap.

1. Overview and Strategic Alignment• Review current IT and business environment• Introduce Cloud concepts and analysis

framework • Determine IT provider relationship profile• Review IT priorities

2. Cloud Opportunity Identification• Identify potential Cloud opportunity areas• Determine desired Cloud targets• Assess potential Cloud workloads

3. Current IT Environment Assessment• Review overall IT readiness for Cloud • Analyze current IT environment and

the future requirements to support Cloud

• Define gaps in current IT capabilities

4. Prioritization of IT Enhancements• Assign priority and estimated effort

to closing each Cloud-related IT gap• Review overall enabling program

5. Final Report Creation• Cloud Computing opportunity

analysis• IT environment gap assessment• Cloud readiness assessment• High-level Cloud roadmap

The Infrastructure Strategy and Planning for Cloud Computing uses an IBM research developed tool to analyze candidate workloads according to its affinity for deployment from a cloud

Characterization of individual workloads– Identification and classification of IT related attributes – Identification and classification of data and business related attributes

Pain vs. Gain analysis and modeling for transformation to Cloud– Interactive information gathering and analysis– Provides qualitative comparison of the pain vs gain by workload class– Has the ability to compare your scenario with industry standards




The result is a pain vs. gain analysis and recommendations for which workloads to move to cloud

Sample Scorecard Gain vs. Pain Sample Output




Where the same characteristic is related to multiple “layers” of Cloud services, it will be assessed just

once and the result used for all relevant layers

Based upon the highest priority cloud opportunity areas, we willassess relevant characteristics of the IT infrastructure
