1 Architecting the Cloud: How EAs should think about Cloud Computing Pratheesh T S

2 Introduction  How many of you are Enterprise Architects? Pratheesh T S

3 Agenda Enterprise Architect role Cloud Computing Cloud Types and different trends Considerations: Architecting Cloud Example: BPOS\ Office 365 and AWS Questions

4 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.

5 Cloud Computing Software As Service Platform As Service Infrastructure As Service …………… As Service

6 Cloud Computing  On Premises  Hosted  Cloud Where do your application "Live“?

7 Cloud Computing Application runs on-premises My own hardware, connectivity, software, etc. Complete control Complete responsibility Upfront capital costs for the infrastructure

8 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

9 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

10 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”

11 Defining Cloud Type 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 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

12 PaaS LOB app Native Cloud app IaaS Iaas and Paas

13 Gartner’s View of Clouds

14 “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.”

15 Some PaaS\ SaaS offers are already quite mature; some others are emerging Maturing Software Segments

16 16 Global Cloud Market Landscape

17 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

18 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.

19 “ 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 “ 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 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 “ 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

20 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

21 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 hosting locations must be re-balanced

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