Cloud Computing and the Next-Generation of Enterprise Architecture - Cloud Computing Expo 2008
- 1. Cloud Computing and the Next Generation of Enterprise Architecture Stuart Charlton Chief Software Architect & VP Products, Elastra The Enterprise Cloud Company www.elastra.com
- 2. Objectives Does cloud computing change the importance and role of enterprise architecture and IT service management? Exploring a reference model for the cloud Suggesting a way to bridge the gap between architectural intent and results through cloud computing 2 www.elastra.com Cloud Computing Expo 2009
- 3. What do you mean by... architecture? Architecture » The fundamental organization of a system, embodied in its components, their relationships to each other, and the environment, and the principles governing its design and evolution. (ISO 42010 / IEEE 1471-2000 definition) Enterprise Architecture » Enterprise Architecture is the organizing logic for businesses and their IT infrastructure reflecting the integration and standardization requirements of the firm’s operating model. Peter Weill, MIT 3 www.elastra.com Cloud Computing Expo 2009
- 4. Architecture as Strategy Idea 1 Idea 2 Idea 3 Strategy Defines Limits Set Policy Constrains Learning Operating Model Enterprise Architecture Provides Requires Capabilities Execution Systems Processes Infrastructure Adapted from: Enterprise Architecture as Strategy: Creating a Foundation for Business Execution, J. Ross, P. Weill, and D. Robertson, Harvard Business School Press, 2006. 4 www.elastra.com Cloud Computing Expo 2009
- 5. A Gap in Realizing Architectural Goals What How Where Who When Why 1. Business Business Information Processes Geography Strategy Organization Events & Collaboration 2. (a miracle occurs) Secured Event Traceable Databases Applications Networks User 3. Processing Models Interfaces 5 www.elastra.com Cloud Computing Expo 2009
- 6. How have we managed our IT? Developer-led » Concurrent Versioning, Unit Testing, Maven, Ant, Capistrano » Focused on code-promotion ; sometimes database transform Manager-led » One extreme: firefighting » The other extreme: bureaucracy Architect-led » Round-trip modeling tools (e.g. Rational UML, Together, etc.) » Gated reviews (i.e. “The technology cops”) Operations-led » Management suites (OpenView, Tivoli, etc.) » Runbook Automation (e.g. HP/OpsWare, BMC/BladeLogic, Opalis) 6 www.elastra.com Cloud Computing Expo 2009
- 7. IT Infrastructure Library (ITIL) v3: The Current Best Practice? 7 www.elastra.com Cloud Computing Expo 2009
- 8. How Far Can Technology Save Us? The “Google Secret Sauce” Theory: » Always available, scalable, fast » Computing as fungible commodity » Reliability is enabled by architecture » But you have to rewrite your software Does a seemingly magical architecture reduce or eliminate the need for If I spill this on a configuration & dependency management? server, who Does this architecture match classic is affected, and by enterprise requirements? how much? 8 www.elastra.com Cloud Computing Expo 2009

- 10. The Cloud Provider Continuum “Retail Ecosystem” “Supplier Ecosystem” Closer to the Closer to the Developer/User SysAdmin/Ops Platform-as-a-Service Infrastructure-as-a-Service 10 www.elastra.com Cloud Computing Expo 2009
- 11. Qualities of an Enterprise Cloud • On-Demand, Services-Oriented Computing » Drastically reduced lead times » Lowered requirement to call-ahead forecasts » Demand trends are predicted by the provider • Variable cost consumption » Pay-by-the-drink or over time; decouple fixed overhead from demand • Self-service » Resources directly/indirectly reserved with a GUI or API • Elastic Scalability » Grow or shrink resources as required • Mandatory Network » The network is essential to consume the service • Governance and Compliance » Tracking and matching of cloud providers to policies 11 www.elastra.com Cloud Computing Expo 2009
- 12. A Cloud Technology Reference Model • Begin with the Data Center • Now Global & Possibly Cross Organizational • Exposes Power & Cooling Information Facilities & Logistics Management Organizationally & Geographically Decentralized Software & Hardware 12 www.elastra.com Cloud Computing Expo 2009
- 13. A Cloud Technology Reference Model • Add Trust, Identity and Licensing • Control Point for Compliance, Auditing • Distributed Action without Replicated Credentials Licensing, Security, Identity & Trust Facilities & Logistics Management Organizationally & Geographically Decentralized Software & Hardware 13 www.elastra.com Cloud Computing Expo 2009
- 14. A Cloud Technology Reference Model • Add easy software access to: • Configurations - HW/SW/Network/Storage Settings, Software Packages, and Dependencies • Resources - Reservations from a pool of excess capacity in storage, computing, and network Licensing, CONFIGURATION RESOURCE Security, Identity MANAGEMENT MANAGEMENT & Trust Facilities & Logistics Management Organizationally & Geographically Decentralized Software & Hardware 14 www.elastra.com Cloud Computing Expo 2009
- 15. A Cloud Technology Reference Model • Add some visibility: • A Hyperlinked Model of Metadata (What uses or contains what other things?) • Lifecycle (when and how can things change?) System Lifecycles & Management Processes Change, Versioning, Autonomic Provisioning, Scale and Recovery Hyperlinked Models & Metadata Capabilities, Configurations, Reservations & Dependencies Licensing, CONFIGURATION RESOURCE Security, Identity MANAGEMENT MANAGEMENT & Trust Facilities & Logistics Management Organizationally & Geographically Decentralized Software & Hardware 15 www.elastra.com Cloud Computing Expo 2009
- 16. A Cloud Technology Reference Model • Add some real-world context: • Governance (Who has authority / responsibility to change, and how?) • Constraints & Policies (How are concerns addressed in the design?) • Testing, Monitoring & Operations (How do we manage & verify?) The IT Service GOVERNANCE Testing, Monitori Constraints & Policies ng & Operations Scalability, Allocation Strategy, Security System Lifecycles & Management Processes Change, Versioning, Autonomic Provisioning, Scale and Recovery 16 www.elastra.com Cloud Computing Expo 2009

- 26. Conclusions Enterprise Architecture helps to prioritize and align an organization’s ability to execute » But there has been long been a communication gap between intensions and results Cloud Computing technology drastically reduces provision lead times and enables quick iteration A Cloud-Oriented synthesis of IT Architecture, Provisioning and Service Management may help bridge the gap » “Architecture-Aware Clouds” 26 www.elastra.com Cloud Computing Expo 2009
