• Business drivers for Cloud

• Probable cloud adoption journey

• Questions and Answers

Cloud computing – a simple definition, major disruption!

Cloud Computing:“IT resources and services that are abstracted from the underlying infrastructure and provided “on-demand” and “at scale” in a multi-tenant environment.”

...such a simple concept ...yet so much confusion!

Buying IT components as a ‘Service”:

Explaining the definition...in simple ways!

Cloud Computing:“IT resources and services that are abstracted from the underlying infrastructure and provided “on-demand” and “at scale” in a multi-tenant environment.”

“IT resources and services that are abstracted from the underlying infrastructure …

…and provided “on-demand” …

… and “at scale”…

…in a multi-tenant environment.”

• Most architectures today are closely coupled – and have strong dependencies between underlying elements.

• All these aspects have to be changed – and elements have to be SEPERATED from each other…this is most often achieved via VIRTUALISATION

• “on-demand’ implies one only sources or buys what you need• In order to do this a HIGH order of automation is required – to allow

one to ‘turn on or turn off’ capacity

• “at scale’” refers to sourcing at a better rate than one can do oneself

• New providers that focus in one area and have many clients have better scale – and thus this typically refers to sourcing from a provider

• This refers to the architecture that providers use to deploy and deliver services.

• It is a way to used shared infrastructure for dedicated offerings

Private Cloud

Public Cloud

Hosted Private Cloud

Virtual Private Cloud

Hybrid Cloud

Community Cloud

• A Cloud architecture that is deployed for the sole use of a single enterprise – and reside on the enterprise premise (i.e. on-premise)

• A Cloud architecture that is deployed for the sole use of a single enterprise – but hosted by a cloud services provider (i.e. off-premise)

• A Cloud architecture that is deployed for the provision of public cloud services – a cloud architecture that serve multiple enterprises – hence sharing of underlying infrastructure elements occur (to varying degrees, based on the actual service type).

• A dedicated partition within a Public Cloud architecture that is allocated to a single enterprise – hence certain elements of the architecture are shared, while others are dedicated to a single enterprise (related to the service type).

• A Cloud architecture that is made up of a combination of previous Cloud Types – most often a combination of Private and Public Cloud Architectures (once again related to the service types).

• A Public Cloud Architecture for the provision of cloud services to a specific or limited community or segment or vertical.

The business benefits of cloud computing…drivers

...why would one not consider these benefits?

• Business continuity

• Technology independence

• Operational complexity

• Specialised skills

Risk optimization

• Time-to-market

• Innovation

• New business models

• Resource leverage

Strategic agility

• No capex, less assets

• Pay-as-you-use

• On-demand capacity

• Elasticity

• Economies of scale

• Time-to-value

Cost optimization

Cloud has appeal to different buyers

“I need a market analytic tool now. I don’t care how it’s delivered to me” • Marketing Manager

“I don’t want to go through the process of a CAPEX request for an application I’m only going to need for 6 months”• HR Manager

“Our staff need access to our inventory management system in real time when they're on the road”• Sales Manager

“Where our tools are stored doesn’t matter to me. I just

want our virtual team to be sharing

work and collaborating as

soon as possible”- Project Manager

Cloud Services, WW Share by Industry Sector

The high-tech, manufacturing and financial services sectors and the public sector will continue to be the most-aggressive adopters of cloud services through 2015

The North American market continues to be, by far, the largest regional market representing 60% of the global market currently, but growth in China remains of interesting potential.

Financial services organizations in aggregate represent the largest users of public cloud services.

Gartner predicts the fastest growing revenue generating segment of public clouds will be storage services (89.5%) followed by Compute Services (47.8%) and supply management (39.5%).

Drivers Adoption rate

Cloud Services: Adoption by market segment will vary

Global• Financial construct• Agility…IT and Biz• Architecture itself

• Have scale, will pursue architecture• Private Clouds first• Test Public Services…non-core• Prefer “gorillas” due to risk

International• Financial construct• Agility…IT and Biz• Time to market and growth risk

• Scale in home markets only• Private and hosted private clouds• Test public services…non-core

Domestic• Affordability and leverage scale• Agility and competitive risk• Time to market and growth risk

• Regulatory compliance impact• Private and hosted private clouds• Test (I/C) public services…non-core

Mid market• Cost• Access to IT functions• Agility…somewhat

• More risk tolerant• Hosted private and public cloud• All service types…non-core and core

SMB• Cost, cost, cost• Ability to do it oneself• Access to IT functions

• Early adopters and rapid rate• Mainly public cloud services• All service types…core apps

15

What are customers’ business and IT triggers for cloud computing?

Triggers Reasons

Reduce IT Complexity Too many systems, vendors , moving parts

Reduce OPEX Spending too much time maintaining and managing IT

Improve work-force productivity Need new collaboration tools, on-demand

Efficient use of resources Under or over utilized silos of resources

Improve Test/Dev cycles Provide cost effective on-demand, self-service Test/Dev environment

Tech-refresh Update ageing infrastructure, software, skill set

Make IT agile and aligned with business needs Scale, support new and existing business workloads effectively

Reduce CAPEX High cost of buying systems, deprecation of assets fast, need a pay-as-u-use model

Expedite time-to-market of revenue generating services

Takes too long to develop, test and provision new services

How will the “Cloud” be used?

New apps – ‘hosted’ SaaS

Current apps – ‘hosted’ SaaS

Dev/test/simulations – on demand, self service

Cloud Hosting

Public Cloud

New apps - as SaaS

Probable Customer adoption:What we are seeing

Key Findings:

• The cloud model is a new consumption model of technology and services

• The business benefits of cloud models are compelling – in many ways

• Adoption will need to be structured – and support existing business systems

• Most likely end state: hybrid model

The move to cloud services is a journey over time…

…and all is not equal!

Lack of In-House Expertise

Launching Public Cloud: roadmap planning, new feature adoption, software and UI

development, upgrades, interoperability, patches, change management, performance

envelopes, compliance, security, etc.
