Identifying and Overcoming Challenges of Cloud Computing from the Enterprise Architecture Perspective

  1. 1. Identifying and Overcoming Challenges of Cloud Computing from the Enterprise Architecture Perspective 2nd Annual Cloud Computing 2011 Dave Chen, CSSLP, TOGAF Founder and Chairman Association of Enterprise Architects, HK Chapter
  2. 2. AgendaSpeaker’s IntroductionIntroduction of AEA and HK Chapter (5 mins)Identifying and Overcoming Challenges of Cloud Computingfrom the Enterprise Architecture Perspective (30 mins)Q&A Discussion (10 mins)
  3. 3. Association of Enterprise ArchitectsAEA (previous named AOGEA) is the definitive professionalassociation for Enterprise ArchitectsOpen Group - Leading the development of open, vendor-neutral IT standards and certificationsEnterprise Architecture Framework, TOGAF Certification15000 Memberships for the Open CA or TOGAF CertifiedOver 30 Chapters worldwide
  4. 4. Introduction to AEA HK ChapterAEA HK is non-profit local HK chapter of AEA and isgoverned by the AEA Bylaws.Committee formed by HK EA PractitionersOur mission is to bring the Enterprise Architectureexperience from worldwide into Hong Kong.Establish a platform for Hong Kong Architects toshare their experience and knowledge, ultimatelypromoting EA in Hong Kong.
  5. 5. Cloud Computing fromEnterprise Architecture Perspective
  6. 6. What is Enterprise Architecture?
  7. 7. Enterprise Architecture Definitions Enterprise Architecture An ‘enterprise’ is any (ISO/IEC 42010:2007) collection of The structure of organisations that has a components, their inter- common set of goals relationships, and the principles and guidelines governing their design and evolution over time - Identify gaps between current (baseline) and future (target) state - Provide a roadmap to achieve business goals and objectives
  8. 8. Enterprise Architecture Belief - EA help IT aligned to Business Objectives - IT & EA is to drive innovation and enrich business strategy Business Strategy Plan Initiatives constraints define Enterprise Architecture Aligning & Information System Improving Business Architecture Prioritizing Architecture Technology Architecture Application Data meta-model utilize IT Process System InfrastructureAdapted from Enterprise Architecture as Strategy, Creating a Foundation for Business Execution, Jeanne W. Ross, Peter Weill, David C. Robertson,Harvard Business School Press , Boston Massachusetts, 2005
  9. 9. Enterprise ArchitecturePerspective on Cloud- To EA, Cloud Computing is just an “Architectural STYLE”, like SOA- EA is the heart of change to organize and Enterprise Architecture manage your services- Adopt EA Framework, e.g. TOGAF well-defined layered architecture and interoperability Cloud Computing- EA help figure out what, when and how to move to the Cloud- EA ensures seamless operations to adapt to cloud-based services
  10. 10. Traditionally, - Heterogeneous ~ monolithic systems, client-server, tiered to distributed architectures - Becoming tightly coupled “spaghetti-like architecture” Biz IT Plan Plan maintain support IT Team Business UnitsGraphic source : aurorisoft.com
  11. 11. With EA, EA helps standardize components with layered architecture and define guidelines and relationships -> IT enrich business strategy Architecture Vision IT & Business Drive Strategy Biz IT Business Information System Technology Plan Plan Architecture Architecture ArchitectureBusiness EA Team maintain Security Architecture Units Architecture Realization TOGAF Architecture Content Framework with Sample Building Blocks

  13. 13. However with Cloud, challenges come •IT Standard •SOA Readiness Violation •Integration •Disjointed Business Incapability Process •Information Silo •Incomplete •Middleware Application Management Portfolio •Security Policy •Maintenance Violation •Performance •Cloud Integration •Availability Security •Data Jurisdiction
  14. 14. Something that EA may help •Define Cloud •IT Standard and Strategy and Guidelines Management •Integration impact •Business analysis to existing Architecture services •Cloud Service •Data Architecture Evaluation IT System Governance Integration Enterprise Architecture IT IT Security Infrastructure •Security along •SLA Requirements the Architecture •IT baseline and Process target platform •IT Security Policy •Cloud-Computing and Compliance Resources
  15. 15. Key Thoughts and going forward- EA is always needed, no matter Cloud or not- Think business objective first, Cloud Technology next- EA aligns IT and business strategy achieving business outcomes- SOA readiness impacts to both Cloud and EA- Without EA, Spaghetti Cloud may occur- EA provides information on Cloud evaluation, adoption, minimize risks on business process integration- Cloud become easier with EA!

  17. 17. Questions & Answers
  18. 18. To-Cloud Considerations Discussions- Not mature to have all computer resources available- Good for newly developed apps, porting/migration is hard- Tight integration with on-premises system is a problem- 24x7 usage may not be cost-effective (pay-as-u-go)- Highly secure apps may not be suitable- ROI and cost calculations are always important- PoC together with going through the EA ADM process
