Transcript of "SOA And Cloud Computing"

  1. 1. SOA and Cloud Computing<br />David Chou<br />david.chou@microsoft.com<br />blogs.msdn.com/dachou<br />
  2. 2. State of SOA<br />Perceptions<br />SOA = IT centralization/standardization<br />“SOA is dead” (Anne Thomas Manes, Burton Group; January 2009)<br />Cloud computing will replace SOA<br />Reality<br />SOA does not solve all enterprise IT issues<br />SOA is complex, and difficult<br />Core value of SOA is agility, but needs vary<br />SOA demands change, but organizational resistance is often the biggest impediment<br />Need to focus on architecture, not technology<br />
  3. 3. SOA Manifesto<br />http://www.soa-manifesto.org/<br />Service orientation is a paradigm that frames what you do. <br />Service-oriented architecture (SOA) is a type of architecture<br />that results from applying service orientation. <br />We have been applying service orientation to help organizations <br />consistently deliver sustainable business value, with increased agility<br />and cost effectiveness, in line with changing business needs. <br />Through our work we have come to prioritize: <br />Business value over technical strategy <br />Strategic goals over project-specific benefits <br />Intrinsic interoperability over custom integration <br />Shared servicesover specific-purpose implementations <br />Flexibilityover optimization <br />Evolutionary refinement over pursuit of initial perfection <br />That is, while we value the items on the right, we value the items on the left more. <br />

Manageability</li></li></ul><li>SOA, Meet Cloud Computing<br />SO-Architecture<br />A different approach to organize enterprise IT resources<br />Governance<br />Management<br />Strategic framework and planning<br />People and process<br />IT-as-a-Service<br />A different model to leverage computing resources<br />Service design<br />Higher-level abstraction<br />Tactical and incremental implementation<br />Data and technology<br />
  19. 19. Extending Enterprise SOA to the Cloud<br />Resources beyond enterprise boundaries (networks without borders)<br />Cloud as a collection of capabilities/services to leverage (“Intercloud” – an interconnected global “cloud of clouds”)<br />Loose-coupling everywhere (in service contracts, data relationships, process dependencies, identity, communication models, performance expectations, change management processes, etc.)<br />More trust needed (lower security requirements, virtual & shared infrastructure, multi-tenancy, Internet transit, etc.)<br />Different fault zones/domains, criticality tiers (one big monolithic SOA vs. federated distributed SOA)<br />New development efforts (instead of moving legacy applications into someone else’s data center)<br />
  20. 20. Web as a Platform<br />“Intercloud”<br />
  21. 21. Emerging Trends<br />De-perimeterization<br />Democratization of industries<br />Dynamic business models<br />Relationship networking core competencies<br />Shifting process centers of gravity<br />Plug-and-play IT architectures<br />Model-driven development<br />
