Service Oriented Cloud Computing Architecture (SOCCA)
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.Individual Cloud Provider LayerEach 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.
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.
Cloud Ontology Mapping LayerCloud 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.Cloud Ontology Mapping LayerOntologyStorage Ontology - for the data manipulation on the cloudsComputing Ontology - concepts and terms related to distributed computing on the clouds.Communication Ontology - concepts and terms related Communication Schema among the clouds.Cloud Broker LayerCloud 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 ModelSOA Layerartifacts 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.SOA LayerServices providers do not host the published services.All services are in deployable packages which can be easily replicated and redeployed to different hosting environment.Multi-tenancy Architecture (MTA)
Single Application Instance and Multiple Service Instances (SAIMSI)Multi-tenancy PatternsMultiple Application Instance (MAI)Single Application Instance (SAI)Single Application Instance and Multiple Service Instances (SAIMSI)
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.
