  1. Cloud Computing Architecture Adam Balla Wa Chiu Siu

  2. Last Presentation We introduced some basic architecture of Cloud Computing. We will a kind of architecture into more details to you

  3. Service Oriented Cloud Computing Architecture (SOCCA)

  4. Service Oriented Cloud Computing Architecture (SOCCA) It is introduced Wei-Tek Tsai and is built to guides business solution to create, organize and reuse its computing components.

  5. Individual Cloud Provider Layer • Each cloud provider builds its own data centers that power the cloud services it provides. • Each cloud has its own proprietary virtualization technology or utilize open source virtualization technology.

  6. A request dispatcher working with Virtual Machine Monitor and Service/App Governance Service to allocate the requests to the available resource. • Cloud Computing resource is componentized into independent services such as Storage Service, Computing Service and Communication Service, with open-standardized interfaces.

  7. Cloud Ontology Mapping Layer • Cloud providers may not strictly conform same standard in a short time. • This layer acts as a mask for differences among different cloud providers. • It helps the migration for users from different cloud providers.

  8. Cloud Ontology Mapping Layer • Ontology • Storage Ontology - for the data manipulation on the clouds • Computing Ontology - concepts and terms related to distributed computing on the clouds. • Communication Ontology - concepts and terms related Communication Schema among the clouds.

  9. Cloud Broker Layer • Cloud brokers serve as the agents between individual cloud providers and SOA layer. • Each major cloud service has an associated service broker type. • Tasks: Cloud Provider Information Publishing, Ranking, Dynamic SLA Negotiation, On-Demand Provision Model

  10. SOA Layer • artifacts like workflow templates, collaboration templates can be published and shared. • The registry for each type of artifacts is indexed and organized by its according ontology.

  11. SOA Layer • Services providers do not host the published services. • All services are in deployable packages which can be easily replicated and redeployed to different hosting environment.

  12. Multi-tenancy Architecture (MTA) Single Application Instance and Multiple Service Instances (SAIMSI)

  13. Multi-tenancy Patterns • Multiple Application Instance (MAI) • Single Application Instance (SAI) • Single Application Instance and Multiple Service Instances (SAIMSI)

  14. Single Application Instance and Multiple Service Instances (SAIMSI) • Workloads are often not distributed evenly among application components, and the performance of the single application instance is limited by the application components having lower throughput. • To enhance scalability, we want to reduce unnecessary duplications as much as possible. • Easy customizability is another gain.
