Architecting the Cloud: How EAs should think about Cloud Computing Pratheesh T S
Introduction Pratheesh T S § How many of you are Enterprise Architects?
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. Business People Process Technology
Cloud Computing Software As Service Platform As Service Infrastructure As Service …………… As Service
Cloud Computing Where do your application "Live“? § On Premises § Hosted § Cloud
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 at a • Bring my own machines, Buy my own connectivity, software, etc. hardware, and manage my own • Complete control and responsibility data center • Upfront capital costs for the infrastructure • Rent machines, connectivity, software Pay someone • Less control, but to host responsibilities fewer my application using capital costs, • Lower hardware that I specify but pay for fixed capacity, even if idle on-premises hoster
Cloud Computing Application runs at a • Bring my own machines, Buy my own connectivity, software, etc. hardware, and manage my own • Complete control and responsibility data center • Upfront capital costs for the infrastructure • Rent machines, connectivity, software Pay someone • Less control, but to host responsibilities fewer my application using capital costs, • Lower hardware that I specify but pay for fixed capacity, even if idle on-premises hoster Application runs using cloud platform • Shared, multi-tenant Pay someone for a environment pool of computing • Offers pool of resources that can computing resources, be applied to a set abstracted from of applications infrastructure • Pay as you go
What is Cloud “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” “A standardized IT capability, such as software, app platform, or infrastructure, delivered via Internet technologies in a payper-use and self-service way”
Defining Cloud Type Public Cloud • Multi tenant Pool of computing resources offered by a vendor , typically using a "Pay as you go" model Private Cloud § Pool of Computing resources that lives within a self managed datacenter § Pool of computing resources that lives within a datacenter with no sharing Hybrid Cloud • Combination of Public or Private cloud and On premises

Gartner’s View of Clouds
“By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets. ” “The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications. ”
Maturing Software Segments Some Paa. S Saa. S offers are already quite mature; some others are emerging
Global Cloud Market Landscape 1
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.
Cloud Considerations: Environmental Sustainability “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 “Transformation in the way people and businesses use technology could reduce annual 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 “Enterprise PCs are wasting money. Far too many organizations leave economic and environmental value on the table by not reducing PC-related energy costs. ” “How Much Money Are Your Idle PCs Wasting? , ” Forrester Research, Inc. , December 2008 “IT's role will increasingly be about applying the technology to create more-energy- efficient, less-carbonintensive 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? Applications & processes have highly variable demand High compute capacities are required to accelerate information discovery and publishing Time-constrained or event-based infrastructure is required to ramp quickly and be disposed of shortly afterwards Speed of provisioning is constraining business execution Existing hardware has reached end of serviceable life and refresh options are being considered Internal datacenter capacity limits are being reached and hosting locations must be re-balanced
Example: BPOSOffice 365 § Global company- Manufacturing § Acquired multiple companies Business Challenges §No integrated IT, more than 5 separate companies not integrated §IT Cost is very high §Some of the infra is end of life cycle §Unused resources §No maturity of IT §Increasing end user needs §Different 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 Share.
