Cloud Computing

On Premises Hosted Cloud

Where do your application "Live“?

Cloud Computing

Application runs on-premises

•My own hardware, connectivity, software, etc.•Complete control•Complete responsibility•Upfront capital costs for the infrastructure

Cloud Computing

Application runs on-premises

Buy my own hardware, and

manage my own data center

Application runs at a hoster

Pay someone to host my

application using hardware that I specify

Application runs on-premises

•Bring my own machines, connectivity, software, etc.•Complete control and responsibility•Upfront capital costs for the infrastructure

Application runs at a hoster

•Rent machines, connectivity, software•Less control, but fewer responsibilities•Lower capital costs, but pay for fixed capacity, even if idle

Cloud Computing

Application runs on-premises

Buy my own hardware, and

manage my own data center

Application runs at a hoster

Pay someone to host my

application using hardware that I specify

Application runs using cloud

platform

Pay someone for a pool of

computing resources that

can be applied to a set of

applications

Application runs on-premises

•Bring my own machines, connectivity, software, etc.•Complete control and responsibility•Upfront capital costs for the infrastructure

Application runs at a hoster

•Rent machines, connectivity, software•Less control, but fewer responsibilities•Lower capital costs, but pay for fixed capacity, even if idle

Application runs using cloud

platform

•Shared, multi-

tenant environment•Offers pool of computing resources, abstracted from infrastructure•Pay as you go

What is Cloud

“A standardized IT capability, such as software, app platform, or infrastructure, delivered via Internet technologies in a

pay-per-use and self-service way”

“Pool of computing resources offered by a vendor, typically using a

“pay as you go” model”

“A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption”

Defining Cloud Type

Private Cloud

Pool of Computing resources that lives within a self managed datacenterPool of computing resources that lives within a datacenter with no sharing

Public Cloud

•Multi tenant Pool of computing resources offered by a vendor , typically using a "Pay as you go" model

Hybrid Cloud

•Combination of Public or Private cloud and On premises

PaaS

Email

LOB app

Native Cloud app

IaaS

Gartner’s View of Clouds

““By 2012, 80% of Fortune 1000 enterprises will By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% be using some cloud computing services, 20% of businesses will own no IT assets.”of businesses will own no IT assets.”

““The bottom line: Early adopters are finding The bottom line: Early adopters are finding serious benefits, meaning that cloud computing serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set is real and warrants your scrutiny as a new set of platforms for business applications.” of platforms for business applications.”

Some PaaS\ SaaS offers are already quite mature; some others are emerging

Global Cloud Market Landscape

Considerations: Cloud• Lower cost: CAPEX, OPEX• Greater agility• Match capacity to demand• How to leverage on-premises, public, private and dedicated cloud

Privacy of data Latency/performance considerations

• Meet requirements for secure communication and compliance • Increase speed to market• Handle complexity of SLA

Considerations: Cloud computing Abstract Resources

Focus on your needs, not on hardware specs. On-demand Provisioning

Ask for what you need, exactly when you need it. Large Scale

Cloud is conceptually of infinite capacity. No Up-front Hardware Investment

Costs are in direct proportion to actual usage. Cost-Effective & Efficient

No investment in depreciating hardware.

“Enterprise PCs are wasting money. Far too many organizations leave economic and

environmental value on the table by notreducing PC-related

energy costs.”“How Much Money Are Your Idle PCs Wasting?,” Forrester Research, Inc.,

December 2008

“Green IT has reached critical mass. Virtually all the companies we surveyed (97 percent) are discussing their

Green strategy.”“Green IT Report Regional Data – United States and Canada: Survey Results,” Symantec, May 2009

Cloud Considerations: Environmental Sustainability

“Transformation in theway people and businessesuse technology could reduceannual man-made global emissions by 15 per cent by 2020 and deliver energy

efficiency savings to global businesses of over

EUR 500 billion [GBP 400 billion/USD 800 billion].”“SMART 2020: Enabling the Low Carbon Economy in the Information Age,” The Climate Group, June 2008

“IT's role will increasingly be about applying the technology to create more-energy-

efficient, less-carbon-intensive business models, enterprises,

value chains, products and services with reduced environmental impact.”“User Survey Analysis: Sustainability and Green IT, Worldwide, 2009,” Gartner, Inc., April 2009

Cloud and Environmental Sustainability

• Lower Carbon Emission due to Multi tenancy Quick Provisioning Optimization of resources Datacenter efficiency Virtualization

Enterprise can reduce the carbon emissions by 20 to 90 percentage by moving to cloud

When Is Cloud Computing Fit For The Enterprise?

Speed of provisioning is constraining business execution

Existing hardware has reached end of serviceable life and refresh options are being considered

Time-constrained or event-based infrastructure is required to ramp quickly and be disposed of shortly afterwards

Applications & processes have highly variable demand

High compute capacities are required to accelerate information discovery and publishing

Internal datacenter capacity limits are being reached and hostinglocations must be re-balanced

Example: BPOS\Office 365 Global company- Manufacturing Acquired multiple companies

Business ChallengesNo integrated IT, more than 5 separate companies not integratedIT Cost is very highSome of the infra is end of life cycleUnused resourcesNo maturity of ITIncreasing end user needsDifferent type of users – Users with high and demands Branding Compliance – ITAR for set of users

EA Approach Reduce IT cost

By Integrating the IT Infra Major IT investment area is

Messaging and Collaboration Cloud based messaging and

Collaboration services. On premise email service for the

specific users need ITAR compliance Overall will reduce the per user

mailbox cost (savings of 27$ per user per month)

Solution approach Consolidated single unified directory

structure Central IT BPOS Cloud based messaging and

Collaboration Services 27$ per user per month saving

Carbon Emission- 79% reduction for Exchange online, 90% reduction for SharePoint

Process BenefitsWhat would it cost you to achieve…

Example: AWS Major Retailer Global Market reach Has existing and future strategies using Web 2.0,

social media, crowdsourcing collaboration etc as part of it marketing and reaching the younger generation

Have Facebook group of over 650,000 members

Speed of deployment and agility are key

Business ChallengesFast changing market by its very natureExpanding Digital Media strategies with accelerated plans for launch of more social and collaborative Web areasReal need for speed of deployment and agilityBusiness groups already empowered to make own choices – IT has to keep up and supportAmbitious timescales for next launch – repeating cycleIncreasing costs of external agencies to host if not in IT

EA Approach Cloud based IaaS and Elastic Computing Cloud Workshop to describe the art of the possible Architect and Design future platform for

Internet/Extranet deployments • Resilience, Scalability, expandable• Support and management• Secure

Solution AWS based Infrastructure as a serviceBusiness Benefits Speed : Rapid deployment cycle enabled

immediate verification of application development, and launch timescales

Cost Reduction: Agility : Can quickly adapt and change in line with

instant business/artistic needs Scalable: To meet needs of planned/unplanned

peaks, and then back to normal volumes Integrated : Into client’s existing monitoring and

management environment, for minimal process impact

Extendible : To take further requirements and need and incorporate into the environment
