Agenda
• Enterprise Architect role• Cloud Computing • Cloud Types and different trends• Considerations: Architecting Cloud• Example: BPOS\ Office 365 and AWS• Questions
Enterprise Architect Alignment of IT strategy with company's business goals. Optimization of information management approaches based on evolving business
needs and technology capabilities. Long-term strategic responsibility Promotion of shared infrastructure and applications to reduce costs Management of the risks associated with information and IT assets through
appropriate standards and security policies.
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

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
““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
Maturing Software Segments
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
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
